Background:  The Klingon Empire are a race of warriors who value honor above all else.  Little is known about their early origins, but the pivotal moment in their history came when a warrior called Kahless brought his people together into one empire.  In 1372 the Hur'q, or what the Klingons would call "the outsiders", invaded the homeworld and stole the sword of Kahless - it would not be back in Klingon hands for many, many years. Meanwhile, the Klingon High Council was growing in politcal power.  In 2069 Kahless (who by now was the Klingon Emperor) died.  No successor was appointed and the High Council found itself in control of the Empire.

First contact between the Empire and the United Federation of Planets came in the year 2218, but unfortunately it didn't go down too well, and the Klingons suddenly found themselves with new enemies.  The Klingons made their first appearance within the Star Trek universe on Stardate 3198.4.  Starfleet suspected that the Klingons would attempt to take over the Organia system, the warriors came - led by Commander Kor.  The starship Enterprise, Captain James T. Kirk commanding, was sent by Starfleet to intercept them.  This first incursion by the Klingons threatened to escalate into an interstellar war. However, either side had counted on the capabilities of the Organians - who looked humanoid, but were in fact a powerful non corporeal life-form.  The Organians used their powers to prevent the outbreak of war between the two sides, and they also imposed the Organian peace treaty on the Federation and Klingons.  They also predicated that, one day, the Federation and Klingons would become friends.

On Stardate 4523.3 the Klingons attempted to sabotage the Federation's claim on Sherman's Planet by poisoning supplies of quadrotriticale, a hyrid wheat which, was very important to the development of Sherman's Planet.  The wheat was being stored on a space station called K-7, which issued a distress call to the USS Enterprise to prevent the Klingons interfering with the project.  The help of Enterprise crew, plus several tribbles (and some time-travellers from the future--DS9: "Trials and Tribbilations"), the Klingons plan to poison the wheat failed.  Klingon Captain Koloth was left with a complaint against Starfleet and a ship full of tribbles - small, cute and furry animals which Klingons hated.  It was later learned that the Klingon Empire had annihilated the Tribbles homeworld (no doubt a glorious victory for the Empire).  Soon afterwards, the Klingons signed a deal with the Romulans, and obtained the technology to cloak their ships in exchange for Klingon design specifications for warships.

Soon after Stardate 5476.3, a life-form which thrives on the emotions of hate and anger lured the USS Enterprise and Klingon forces lead by Commander Kang into a conflict with each other on the planet Beta XII-A.  Kirk and Kang were successful in driving the life-form away.  On Stardate 7412.6, three Klingon starships were destroyed by a powerful "living machine" called V'ger.  Luckily for the Federation, Admiral Kirk had better luck at initiating first contact with V'ger.  Around this same time, the Klingons won a victory over the Romulans at the battle of Klach D'kel Brakt, thanks to Commander Kor.  The Klingons were still determined to gain the upper-hand over the Federation, and while the Klingons were in peace talks with the Federation around Stardate 8210.3 the Klingon Commander Kruge attempted to steal the secrets of the Federation's Genesis project - which could destroy life on a planet as easily as it could create it.  Kirk was successful in stopping the Klingons, but only at great cost - the Admiral lost the Enterprise and his son.  The death of his son would result in Kirk hating Klingons for years to come.  As a result of the destruction of the Enterprise Kirk was demoted to the rank of Captain on Stardate 8454.1

In the year 2292, the alliance between the Klingons and Romulan Empire ended, and the former allies would become bitter enemies for at least the next 75 years.  Stardate 9521.6 proved to be the major turning point for the relationship between the Klingon Empire and the Federation.  The Klingon moon Praxis exploded, causing extensinve damage to the atmosphere of the Klingon homeworld.  The Empire didn't have the resources to cope with this disaster, and realizing that they could no longer afford to continue the long running conflict with the Federation now that they had to look for a new homeworld.  Negotiations between the two superpowers soon opened, and Klingon Chancellor Gorkon agreed to travel to Earth to talk peace with the Federation.  However, forces within the Klingon Empire, the Romulan Empire and the Federation were scared of what lay ahead in the future if the status-quo was altered by the outcome of these talks.  They arranged the murder of the Chancellor before he got to Earth.  Captain Kirk, along with Chief Medical Officer Leonard McCoy, were framed for the murder of the Chancellor and both men were arrested under Interstellar law by the Klingons.  Captain Spock discovered what was really going on, and managed to rescue Kirk and McCoy.  Despite interference from a prototype Klingon bird-of prey which was capable of firing while cloaked, the crews of the Enterprise and Excelsor (Captain Sulu commanding) were then successful in preventing the assassination of the Federation President who wanted the peace process to continue.

The Khitomer Conference would be the start of a new friendship between the two powers.  Peace didn't break out overnight, but peace was achieved over the following years thanks to a better understanding, from a Klingon point of view, of the Federation and what they stood for.  The Enterprise-C, under the command of Captain Rachel Garrett, played a major part in cementing the new friendship in the year 2344 by defending the Klingon outpost Narendra III from a Romulan attack.  The Enterprise-C was destroyed in the process, but a Federation starship defending Klingons from destruction was further proof that the Federation was indeed, a worth ally.  However, the Romulans attacked the Klingon outpost on Khitomer in the year 2346, and thanks to a Romulan collaborator, the attack was successful and 4,000 Klingons lost their lives.  By 2352, the Klingons were enjoying a beneficial relationship with the Federation, to the point that by 2364, when the Galaxy-Class starship Enterprise-D was launched, there was the first Klingon Officer on board (Lieutenant Worf, son of Mogh).

Despite the new era of peace, there were Klingons who thought that the Empire has "lost its teeth" by becoming allies with the Federation.  Worf met two Klingons who thought this way on Stardate 41503.7.  He was forced to kill his fellow warriors when they attempted to take over the Enterprise.  Later, on Stardate 42901.3, Worf had to help deal with some more Klingons who still thought that the Federation were still the enemy.  The crew of the Klingon sleeper ship T'Ong were sent on their mission before the Khitomer peace conference, when they woke up they were in Federation space, and with the help of Worf, and Emissary K'Ehleyr, the T'Ong decided to stand down instead of opening fire on Federation planets.  By this time, officer exchange programs were in effect between the Empire and the Federation.  Commander Riker, the 1st officer on the Enterprise, took part on one exchange on Stardate 42506.5.  Despite a misunderstanding between the Enterprise and his Klingon Commander, Riker acquitted himself well.

On Stardate 43685.2, Commander Kurn came onboard the Enterprise as part of the exchange program.  He later explained to Worf that they are actually brothers, and that their late father, Mogh, was being accused by the Klingon High Council of betraying his people by giving the Romulans the shield access codes for the Khitomer outpost, which resulted in the Khitomer massacre of 4000 Klingons in 2346.  Investigations by the Enterprise crew revealed that the real traitor was Ja'rod, father of Council member Duras, and that the Council had attempted to blame Worf.  The Duras family was very powerful, and if the truth was discovered, the results could have resulted in civil war, or even the end of the peace treaty between the Empire and Federation.  In the end, Worf puts the best interests of his people first by accepting discommendation from the Klingon Empire.  On Stardate 44246.3, K'Ehleyr returned to the Enterprise with the news that Chancellor K'mpec, the leader of the High Council, had been poisoned by his enemies.  K'mpec feared that whoever carried out this dishonorable act could take over the Empire and plunge it into civil war.  He requested that Captain Picard of the Enterprise choose the next leader of the Klingon Empire, since no Klingon could be trusted.  The cantidates for the new Chancellor were Duras, who was partly responsible for Worf's disacommodation, and Gowron, a newcomer to Klingon politics.  During the ja'chuq (right of succession) process, a bomb exploded which almost killed Gowron and Duras.  Both men suspected the other of planting the bomb, which was revealed to be of Romulan design.  K'Ehleyr uncovered the truth about the High Council's decision to punish Worf to protect the Empire from falling apart, and confronted Duras with the truth.  Duras kills her to protect the sins of his father.  Worf in retaliation revealed Duras secret, discrediting him, and Gowron, who faced no other challengers, became the new leader of the Klingon Empire.

There were still Klingon warriors out there who didn't like how "weak" their Empire had become.  One such Klingon, a exchange exobiologist called J'Ddan, was found guilty of giving the Romulans detailed schematics of Enterprise-D's dilithuim chamber.  J'Ddan believed that the Romulans were strong and that they would make a worthly ally for his people. He wasn't the only Klingon who felt this way, the Romulan Empire around this time had re-doubled their efforts to split the Federation and Klingon Empire.  On Stardate 44885.5 they kidnapped Enterprise-D's Chief Engineer Georgi La Forge, and brainwashed him to kill Vagh, the Klingon Governor to the Kriosian colonies.  If the plan had succeeded, it would have dealt a serious blow to the Klingon-Federation alliance.  It was discovered that Klingon emissary Kell was helping the Romulans in their plan by transmitting signals directly to La Forge's brain through his visor.  On Stardate 44995.3, Picard was on-route to the Klingon Homeworld to attend the installation of Gowron as Chancellor of the High Council;  when the Enterprise was intercepted by Gowron who believed that the other members of the Duras family were planning to somehow stop him from becoming leader.  Lursa and B'Etor, the sisters of the Duras family, discovered that their late brother Duras did indeed have a son, Toral.  They attempted to install him as leader of the High Council.  Certain High Council members were friends and allies to the House of Duras decided to ignore Klingon law to follow Lursa and B'Etor.  The High Council was split apart, and caused a Civil War.  Despite a formal request for assistance from Gowron, Starfleet declined to offer their support due to the Federation's Prime directive of non-interference in the political changes of alien races.

By the third week of the war, despite Gowron's forces destroying the Duras supply base in the Mempa Sector, the Duras family had inflected heavy losses on Gowron's forces.  Many suspected that the Duras family was receiving help from the Romulans.  Captain Picard pointed out to his superiors that a victory for the Duras family would mean the death of the Federation-Klingon alliance and the birth of a new Romulan-Klingon Alliance.  Picard proposed to Starfleet that a blockade on the Klingon-Romulan border should prevent any Romulan involvement in the war.  Using a tachyon network grid which, in theory, would detect any cloaked Romulan ships attempting to enter Klingon space, Starfleet gave the green light to Picard's plan and the blockade was set up shortly afterwards, and Picard asked Gowron to launch a full scale attack on the warriors loyal to the Duras family.  The attack went ahead, and Lursa and B'Tor were forced to request new supplies from the Romulans.  The Romulans were successful in temporarily disrupting part of the tachyon grid, but were soon detected within Klingon space thanks to Commander Data.  The news of Duras's connection to the Romulans became clear, and support fell away from the House of Duras ending the war.  The Romulan ships returned home, Lursa and B'Tor escaped, Worf spared the life of Toral and honor was returned to the House of Mogh.  Six months later, Starfleet discovered that no mention was made of their help to the Klingons during the civil war as Gowron had decided to take all of the glory for himself.

On Stardate 46852.2, Kahless the Unforgettable returned, fulfilling a centuries old prophesy. Further investigation by Worf and the crew of the Enterprise revealed that this Kathless was actually a clone, created by the clerics of Boreth.  Despite this, it became clear to Gowron that many Klingons were hungry for the spiritual guidance and leadership which even a cloned Kahless could provide.  At the advice of Worf, Gowron announced that the clone should be considered by all Klingons as the real Kahless, who was also appointed the new Emperor of the Empire, but political power still remained with Gowron and the High Council.

Around this same time the Duras Sisters teamed up with Dr. Tolian Soran.  Soran needed the support of the sisters to help him return to the Nexus, a temporal energy ribbon which offers complete joy to anyone who successfully enters it.  In return for their help, the sisters would get their hands on a trilithium based weapon which was capable of destroying entire star systems.  The crew of the Enterprise-D interfered with their plans, and despite the sisters bird-of-prey causing severe damage to the Galaxy-class starship, they were destroyed by the Enterprise-D, which suffered a warp-core breach caused by the attack.

The Alpha Quadrant was now becoming aware of the growing Dominion threat.  There was concern in the Empire about the presence of the Changeling Founders within the Quadrant, certain Klingons were alarmed when the Cardassian Union was taken over by a new Civilian Government.  Many Klingons found it hard to believe that the Underground movement on Cardassia Prime could seize power from the powerful Central Command, and the Empire interpreted this change on Cardassia as the first step of a Dominion plan to seize control of the entire Quadrant.  This paranoia was enhanced by those warriors who had become bored and restless of being at peace with everyone;  Klingons they argued, were born to fight and to conquer, not to open up restaurants on Bajoran space stations.  After some pressure from the Klingon Military, Gowron decided to protect Klingon interests in the Quadrant by invading Cardassia.  Over a third of the fleet was allocated for this operation lead by General Martok.  Several people in the Empire opposed the decision to attack Cardassia, among them were Emperor Kahless and Worf's brother Kurn, who by now was a member of the High Council.  Captain Sisko of DS9, with help from Commander Worf, discovered the Klingons intentions and warned Martok that a unprovoked attack on Cardassia would probably mean the end of the Khitomer treaty.  Martok proceeded with the attack as ordered, the Federation Council condemned the Klingon invasion, and as a result Gowron recalled all of his ambassadors from Federation space, expelled Federation Citizens from Klingon space, and declared the Khitomer treaty to be dead....

The Klingon invasion fleet broke through the Cardassian Military resistance, and continued on their way to Cardassia to seize control of the planet and execute the Civilian Government.  With the help of Gul Dukat and Captain Sisko, the Civilian leaders were able to escape Cardassian space and ended up on DS9;  where, Gowron and General Martok demanded the return of the Civilian leaders, Sisko refused and soon DS9 was under attack from a massive Klingon task force.  DS9 had been upgraded with new weapons systems only a year earlier in case of Dominion attack, and the Klingons had a first hand demonstration of what DS9's weapons were capable of.  The attack on DS9 ended when Sisko reminded Gowron that this is exactly what the Founders from the Gamma Quadrant wanted, the former allies fighting each other.  That fact, plus the news that Starfleet reinforcements were on the way, persuaded Gowron to call off the attack on DS9 and the invasion of Cardassia. However, Klingon forces were by now occupying several worlds within Cardassian territory.  Lieutenant Commander Worf was expelled from the Empire for not supporting the invasion.  All lands and property belonging to the house of Mogh were seized, and Kurn was kicked out of the High Council.  Gowron returned to the Klingon homeworld, recalled most of his forces, and declared victory.  He ordered his people to re-assert Klingon interests throughout the Quadrant, including several attacks on Romulan outposts along the Klingon-Romulan border.

While the Empire was busy fortifying its position within Cardassian space, Dahr Master Kor, Worf and Dax went on a quest to recover the Sword of Kathless, taken from the Klingon homeworld many years ago.  The trio travelled to the Gamma Quadrant and were successful in locating the sword, but they were unprepared for the potential of the sword to divide the Empire, which was demonstrated by the way Worf and Kor turned against each other.  Toral, son of Duras, whose life Worf spared after the Civil War arrived and claimed the sword;  wanting to return home and make a bid for the leadership of his people.  Fortunately, he was stopped by Dax, and the sword was released onto a distant part of the Gamma Quadrant, where it could do no further harm to the Empire.  The Empire continued to strengthen its position within Cardassian space, and when some Bajorans and Cardassians met on the outpost at Korma for a conference they were attacked and killed by a Klingon warriors, the warriors responsible for this were tracked down and killed by the combined efforts of Major Kira Nerys and Gul Dukat, who in the process claimed the first Bird-of prey to be captured by Cardassia in their conflict with the Empire.  Dukat would later wage a personal war against the Klingons, due to the lack of support he received from the Cardassian Central Command for a offensive against Klingon forces.

On Stardate 49556.2 the Klingons proved to the Federation that they were planning ahead for eventual conflicts when they attempted to cut off the Bajoran system by surrounding it with cloaked mines.  Their attempt failed thanks to the efforts of the sons of Mogh (Worf and his brother Kurn).  On Stardate 49665.3 the Empire attempted to end the Federation's policy of escorting Cardassian relief convoys by engineering a unprovoked attack by the USS Defiant (Commander Worf commanding) on a Klingon Civilian transport.  Further investigations proved that there were in fact no Klingon nationals onboard the doomed transport vessel.  Towards the end of the year 2371, the peace talks between the Klingon Empire and the Federation came to an end, and the Empire was insulted by the Federation's demands that they should leave Cardassian space.  In response, Chancellor Gowron called off the talks and demanded that the Federation should withdraw from the Archanis Sector, an area of space which the Empire had given up its claim to centuries ago.

Odo, the security chief on DS9, a changling discovered through the Great Link of his people, that Chancellor Gowron, the leader of the Klingon Empire, had been replaced by one of the Founders.  By now, "Gowron" had warned the Federation that they had ten days to withdraw from the Archanis Sector - failure to comply would mean war.  Ten days later, the Klingon Empire was at war with their former Federation allies.  The result of this, and Odo's suspicions about the true nature of the Chancellor, resulted in Starfleet giving Captain Sisko a dangerous assignment on Stardate 50013.9 to infiltrate Tiger Core, the location of Klingon Military Headquarters, and to expose the Gowron Changeling.  Sisko, along with other members of DS9's senior staff, disguised themselves as Klingon warriors and with the help of Gul Dukat and his Bird-of prey, infiltrated Tiger Core.  The team was discovered by General Martok, the leader of the fleet which attacked Cardassia a year ago, and Sisko and company were thrown into a holding cell.  Martok informed Sisko of his suspicion that Gowron isn't who he seems.  Martok tells the Captain that he will release them, if they agree to kill the Gowron Changeling.  Sisko agrees and Worf and the Changeling masquerading as Gowron are in a battle to the death, but before Worf can deliver the blow which in theory, would have proved that Gowron was a Changeling, Odo discovered that General Martok was the changeling at the heart of the Empire.  Once exposed by Odo, the Martok Changeling was killed by several Klingon Disrupter blasts.  These dramatic events resulted in a cease-fire of the war, Gowron admitted that Martok had pushed him to launch an attack against the Federation in hopes that the Martok Changeling would have taken over the Empire and continued the war upon Gowron's death, thus weakening the Empire and Federation enough so that the Jem'Hadar could invade the Alpha Quadrant with minimal resistance.

On Stardate 50560.1 the crew of DS9 learned that a Jem'Hadar invasion of the Alpha Quadrant was imminent.  Thanks to the Dominion-engineered war with the Federation, the Empire wasn't in a position to send a fleet of ships to DS9.  Starfleet weren't much better off, the Romulans still had the painful memory of what happened to the Tal'Shiar in their minds, and the Cardassian fleet was a shambles, thanks partly to the Martok Changeling.  After taking all of this into account, the decision was made to close the wormhole - however, thanks to the work of a Founder onboard DS9, the attempt failed and the Jem'Hadar fleet entered the Alpha Quadrant.  Gul Dukat announced that Cardassia had agreed to join the Dominion the week before, and the Gul escorted the Jem'Hadar to Cardassian territory.  Once there, they defeated the Klingon forces which had occupied Cardassian space for the past 18 months.  Dukat later revealed that one of the reasons for joining the Dominion was to get rid of the Klingons, and he also revealed that he intended to retake all that his people had lost - including DS9.  The battered Klingon fleet was withdrawn to the Bajoran system, where Captain Sisko asked Chancellor Gowron to consider re-signing the Khitomer Accords to stand united against the Dominion.  Gowron agreed, and the two enemies were friends once again.  Soon, a large number of Klingon and Federation ships was in the Bajoran system, ready to defend the station from the expected Dominion attack.  Just before the impending attack the Romulans, joined the fleet.  Eventually it was discovered that there was in fact no Dominion fleet on the way to attack DS9, and that this was a attempt by the Founders to destroy the Bajoran system, DS9, and the combined fleet by making the Bajoran Sun go nova.  The Changeling's plan was foiled thanks to some fine work by Major Kira and Lieutenant Commander Dax on board the USS Defiant.  It was later discovered that the real General Martok was still alive, and had been replaced by his Changeling impostor two years earlier (which also meant that the Martok which was in charge of the Cardassian invasion fleet was a Founder).  Once he was safely returned to the Alpha Quadrant, Martok was made commander of the Klingon forces which were now stationed onboard DS9, as part of the new Khitomer Accords treaty. 

Over the next few months, the Dominion sent four convoys through the wormhole to their new Cardassian friends.  Starfleet realized that it was only a matter of time before they attempted to take over the rest of the Quadrant.  When another Dominion convoy came through the wormhole around Stardate 50975.2, Starfleet started talking to the Klingons about a daring plan to destroy Dominion shipyards within Cardassian space.  While the Federation and Klingon fleet were doing this, Captain Sisko mining the Bajoran wormhole in an attempt to distract the Dominion.  The shipyards were destroyed, but DS9 was abandoned by all Starfleet and Klingon personnel, leaving the Dominion as the new masters of the Bajoran space station.  Over the next three months, both the Empire and the Federation suffered horrendous losses to the Jem'Hadar.  The Seventh fleet lost over 90 ships to the Jem'Hadar in one engagement.  The Klingons continued to fight alongside their Federation allies, with many warriors eager to answer the call to battle.  When news reached Starfleet that the minefield was about to be brought down by the Dominion, three Federation fleets left Starbase 375, backed up by a large Klingon fleet, arrived to recapture Terok Nor.  Once there, they were met by a large Dominion fleet, and what followed was a most glorious battle!  The Dominion were successful in dismantling the minefield, and it seemed emminent that 2,800 Dominion ships on the Gamma Quadrant side of the wormhole would arrive to turn the battle to the Dominion side.  As the Dominion's reinforcements were travelling through the wormhole, they were intercepted by the USS Defiant, but before the Defiant could be destroyed, the wormhole aliens, also known as the Prophets of Bajor, took their Emissary, Captain Sisko;  they didn't want him to die, but they didn't realize what was about to happen if the Dominion's reinforcements were allowed through the wormhole.  The Emissary filled them in on the grim situation, and the Prophets decided that now was the time to act;  making all 2,800 Dominion ships vanish.  With more Starfleet ships entering the battle, the Dominion decided to withdraw from DS9, back to Cardassian space.  The battle had been won by the Klingons and Federation, but the war was by no means over.  General Martok was made Commander of the Ninth Fleet which was now protecting DS9.

Some time later, the Empire, thanks to Starfleet Intelligence, discovered a Dominion plot to assassinate a Klingon ambassador who had voiced concern about the Klingon's involvement in the Federation-Dominion war.  The assassination was planned to look as if Klingons had killed the ambassador, and the whole operation was to be carried out by the Orion Syndicate, who had recently became the Dominion's latest allies.  Thanks to Starfleet, the Empire was able to stop their ambassador from making a early visit to Sto-Vo-Kor.  Good news for the Klingons (and potentially most of the Quadrant) arrived when news came through of the Romulans breaking the non-aggression pact they had signed with the Dominion.  This was due to the death of Romulan Senator Vreenak, the man who had signed the pact with the Dominion.  The Romulans believed that the Dominion had killed Vreenak, and attacked several Cardassian outposts along the Cardassian/Dominion border.  It now looks likely that the Klingons will find themselves working with the Romulans for the foreseeable future of the Dominion War, but considering the rather unpleasant relationship between the two powers over the years, it remains to be seen how long this arrangement will last for.  Perhaps this will be the beginning of a new friendship between the Klingons and the Romulans;  perhaps not.  With the Dominion war set to continue for at least another year, there has never been a better time for all Klingon Warriors to pursue the honour and glory that they crave.  Will the call to battle be enough to save the Klingon Empire and the rest of the Alpha Quadrant?  Only time and more glorious battles will tell...

Editors Notes:  Klingons are larger than Terrans with a greater percentage of their body weight being muscle.  They are proficient in the use of ritual hand-to-hand weapons and unarmed combat, and will actually prefer to fight using these methods over beam weapons.  All Klingons will train in at least the bat'telh and the d'k tahg, and many frequently train in some of the other ceremonial Klingon weapons.  Some also train in Mok'bara - the Klingon martial art form.

The Klingon forehead is a major distinguishing feature of this race, consisting of a ridged, bony pattern.  This pattern is different for every Klingon, and is as distinguishing as fingerprints.  A common curse heard among them is: "Hab Sosil' Quch", which means, "Your mother has a smooth forehead."  Also, a bony backbone resembling that of a dinosaur runs up and down their spine.  They have enhanced senses;  acute taste and smell, and acute vision, are genetic, but the third, combat reflexes, is learned from childhood, and is therefore second nature to Klingons.

Klingon warriors pride themselves on their combat abilities and feel the greatest honor that can be bestowed on warriors is to die in combat.

The Klingons hatred of the cute, cuddly Tribble is unexplainable.  Tribbles are banned from being transported to, or traded in, Klingon space.  An old Klingon toast reflects their dislike of this animal.  It goes: "QuvlIjDaq yIH tu'be'lu'jaj." ("May your coordinates be free of Tribbles.")  Tribbles also share the dislike of Klingons. Instead of the usual purr, Tribbles will shriek if even exposed to a Klingon.
