In late 2002 the Void Engineers managed to pinpoint the location of Burn, the Horizon Realm in the deep umbra that had been claimed by the Nyphandic lord Zach Pardane as his personal fortress realm. Hoping to kill Zach Pardane and spread his armies before the so called fourth Nyphandi faction could get off the ground, Fleet Command decided to send the whole of the vaunted First Assault Fleet on a surprise attack. Along with the main assault group were sent six specially converted corvettes, each carrying a high-level combat specialist, intending to break through the lines and assassinate Pardane himself. The battle was a stalemate, with tremendous cassulties on either side, until the battle within the fortress itself ws resolved. Four of the six corvettes delivered they operatives, but all were killed by Pardane. Once he himself emerged to rally his forces the Fleet was forced to retreat back into the Void. Though the Void Engineers took a serious blow to their fleet strength and failed in their objective, they did enough damage both to the demons on Burn and to the realm itself that it can be assumed that the Nyphandi there will be of little concern for sometime.
