The Illarhi were a primitive humanoid race that lived on the planet Illarh.
History and specifics[]
They had copper-colored skin, mossy white hair, shiny black eyes, and bubbles on their cheeks that allowed them to hear.
In the year 2373, the Illarhi allowed themselves to be conquered without a fight by Jem'Hadar forces under the command of the Vorta Sejeel. The Jem'Hadar forces were removed shortly afterward by Starfleet. (STA - Tales of the Dominion War short story: "What Dreams May Come")
