The Lyssarian Prime Conclave was the lead government of the Lyssarians. Prior to 2153, the Lyssarian Prime Conclave declared the creation of mimetic simbiots using Lyssarian Desert Larvae illegal due to the ethical ramifications of creating living, sentient beings. This dictate was defied by the Velandran Circle, a group of Lyssarian scientists, whose illegal research on simbiots had led them to make largely unsubstantiated claims of a way to stop the rapid aging process.
