The Ilari are from the planet Ilari located in the
Delta Quadrant. They are a warp capable species with a strict form of
government. The highest position in the government is that of Autarch.
That Ilari is marked by a silver Collar of Office.
A short civil war broke out on the planet when a former
Autarch, Tieran, from the 22nd century had technology that allowed him to
transfer to different bodies. He took control of U.S.S. Voyager
crewmember Kes and used her telepathic abilities for dangerous uses. He
killed the current Autarch.
Voyager's holographic doctor was able to separate Kes
from Tieran. The dead Autarch eldest son became the new Autarch. The
younger son had join Tieran.
