When the Drifting Star Falls

Ardazephni isn't normal. He is simply an existing being drifting about in space. Oh, and he's immortal and all-knowing.

When he crash lands on a planet named Zeta, several variables start to appear that changes him, even though nothing has done so after an unknown amount of time in space. Questions start to arise, one of them being, why is he even alive in the first place? And why is this idiot who didn't know how to sit on a couch correctly being trusted with a gun during an apocalypse?
