So I have a question based on a different character I'm thinking of reserving.

I play a version of Orpheus from Greek mythology that is sort of post-canon? In that, he goes through all the events of his general mythology, and then after he's been a disembodied head in a cave on Lesbos for a while, he gets given his body back and lives through to the modern era. Is this sort of thing all right, or would I need to app him from his time in canon?
