The Drow was the default model of the “who do you dream of” character in character creation. It can be any race or gender. It will show up if you use your tadpole powers.
Raphael didn’t show up in my first playthrough until I was already at the level cap, right before I left the underdark. I think it might be tied to how often you visit your camp, as I did so only 5 or 6 times in my first run.
