Zener

The Zeners (non-canonic name; the species have never been named in canon) 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 Zeners are known to abduct other species and install cybernetic implants of them; they have been known to work for the Drakhs, which are also servants of the Shadows. Zeners appearance and behavior are very similar to that of the Streib, although production members have denied the two races being related.
