Alright, I thought he was a god because Tech said he could do things with magic no human could.
But I guess that doesn’t necessarily make him a god, since there are races other than humans, or he just meant that no human should be able to do the things he does.
During his dialogue in mount othrys, I think he mentions something about how he hated his family. It’s possible that something caused a rift between him and the other gods, causing him to join forces with a human.
The Apollo on his crew was just a man named apollo, not the actual god
