So… made a mistake.
One of my players is playing a tiefling wildmagic sorcerer, but they said they want to be the child of the embodiment of rage (they’re basing most of their story off of their real life, for a bit of closure) and I said sure. I haven’t done extensive research into eberron until I actually started, so I fixed things where I needed to, but now I realize that even though they’re a tiefling, what they’re describing is perfectly The Dreaming Dark, as their character is artistic and had imaginary friends, and even the embodiment of rage fits an extremely powerful Du’ulora quori, so is there any way to fix this before it gets too complicated?
I should mention that this campaign is like 70% in the city of Sharn, where most of the characters come from
