Sages

Summary
Sages are god-like beings, and are one of the oldest species in the universe. Sage cults and other believers think that Sages are the first they were the first organics to achieve sentience, and transcendence. They say Sages are indistinguishable from Gods. After a crisis on their homeworld, they'd begin a large scale migration to other worlds and civilizations to provide their take on society.
