Gonna piggyback off of this question since it's kind of related, if that's okay!

Uendo here also has multiple personalities, but in his case it's very explicitly stated to be caused by a mental illness, specifically Dissociative Identity Disorder. While they do all have different names and traits and so on, they're still parts of the same psyche and can't exist independently of one another.

I just wanted to make sure they're appable as a single character -- it'd be pretty much impossible to play Uendo without his alters when they're so intrinsic to who he is as a person. (That, and I'd feel really weird about just magicking away someone's mental illness.)
