Tzzz-Tzer-Tzak

Tzzz-Tzer-Tzak was a Chenjesu historian whose research indicated the existence of the Sentient Milieu. He was able to find that one of the members of the Milieu was a "race of rocklike creatures" (most likely the Taalo) whose homeworld orbits one of the stars of the Vulpeculae system.

Tzzz-Tzer-Tzak's research was read by Commander Hayes, who then revealed it to The Captain.
