Alien Species

The Zener are one of the many servant species of the Shadows. They are grey-skinned humanoids with black pupil-less eyes, bony skin and long fingers; and serve their masters mostly as surgeons and scientists.

The Zener are known to abduct other species and install cybernetic implants in them. They have been known to work for the Drakhs, which are also servants of the Shadows.


  • The name Zener is not considered canon, and the species has never been named in the series proper. The name originates from Darkness & Light: The Vorlon & Shadow Fact Book, by Gareth Hanrahan.
  • The Zener's appearance and behavior are very similar to that of the Streib, although production members have denied the two races being related.
