| Background | The Zetarians are a race by now exctinct. When their world blew up, they formed a collective entity formed by emotions of last Zetarians. This collective mind sought a new host body to transfer to, but attempts to keep control of a human (or Tellarite or Andorian) destroyed the mind of the host causing death within moments. |
| Editors Notes | Extinct Race. The Zetarians were able to move faster than light speed by using unknown means of propulsion. Any being possesed by the Zetarians has lights in his eyes, and when trying to avoid possession he exhibits color change of the face and begins to wheeze indicating death is imminent. Should cause extreme pain to telepaths from the mass of collective thoughts. |
