Urhua Thereaux was an Assassin of the Venenum Temple, sent to assassinate the renegade Planetary Governor Yawell in 563.M37. The ship Thereaux was travelling on departed but was caught in a warp rift which held it in temporal stasis for 698 years.
When the ship emerged, Thereaux and the crew were unaware of the temporal shift. Thereaux proceeded to the target, only to find the Governor long dead and replaced by an anti-Imperial committee with one thousand members. Given that the rulers of the world were still anti-Imperial, Thereaux spent three days poisoning each of the chairs in the council auditorium to kill all of the members.
