D&D 5E Corellion The Chaotic God

[epithet]

If you're looking for some kind of powerful patron to flesh out your character's backstory and personality, you might look to an archfey instead of a god.

See, for example, this:

[I'm A Banana]

Corellon desires to protect and preserve the elven race, return to his people their lost artistic heritage, and to thwart the schemes of the drow and the orcs. This also means guarding against the corruption within that resulted in the creation of the drow. Corellon advises his faithful to guard against stagnation as well, continually seeking out new experiences. They seek to bring out beauty through art, craft, and magic.

Corellon is surprisingly humble, for a regent of his stature.

So do that.
