I have an NPC I built that, well, I hadn’t intended to get quite this tied up in the story. But, hey, that’s how it goes sometimes. I want to make a full character for them, but I’m not sure if there is a standard class to try and shoehorn them into, or if I need to just find a template and start rolling my own.
Basically, they are a "shard of a deity". Through some mechanic (that I don’t have a definition for) some significant piece of the essence/personality/spirit of Sune (D&D, Forgotten Realms) exited her plane and imbued itself into an unborn child (a character named Shaylynn). As a result, this character looks like Sune and has a lot of the personality (and decent amount of the power) of that deity.
But, while she contains, and is a part of Sune, she is an entirely independent being. Granted, Sune may like that part of herself back, but at the moment I don’t think she’s in any rush.
Are there any classes (or even just creatures) that fit this kind of description? I called her an avatar at first (she’s like the avatar of a deity, but with her own consciousness and will) but I don’t think that’s how avatars are intend to work in Forgotten Realms.
Anyway, I would prefer something canon (if at all possible, it keeps my life simpler). If there isn’t one, perhaps an example from mythology so that I can at least have some lore to work with?
Failing all of that, perhaps some guidance on a template to use so I can start making the class myself.
