What is Spiritmogus?[]
Spiritmogus is a spiritual being composed of hundreds, if not thousands of dead Crewmate souls. It is a hungry spirit that can take your soul away, and become bigger and stronger.
It only lives in the Spiritual World as the judge of it, where spiritual beings live. It cannot interact with material/physical things, except steal the souls of living entities.
What is Spiritmogus' origin?[]
Spiritmogus were first 5 crewmates whom died at the same spot at the same time (via unstable reactor). The universe had no idea how to deal with this and just fused them together creating a powerful being.
Over time their minds decayed and focused on one goal: become more powerful, by absorbing more crewmate souls.

The Holy Knights of the Cosmos attempted to get rid of Spiritmogus with their spiritual powers but it had no effect and the Knights were almost wiped out and got absorbed.
When Spiritmogus was weaker, it could posses a physical body, and it could use it to gather more souls. But Spiritmogus is now way stronger, any being it posses lose consciousness. But beings stronger than it can easily repel Spiritmogus' spiritual force and stop it from possesing them.
