Unknown how well implemented this voodoo fey/goblin companion of ours is going to be. We already have the tadpole in our heads, I can see it potentially becoming obnoxious. It also seems like we won't be able to have a name for our character if we go this route? in the Stream they were just called 'The Dark Urge' IIRC.
It seemed to me like "The Dark Urge" was a title, not a name. Something to distinguish it from "Vanilla" Tav. I doubt you'll be introducing yourself to NPCs as The Dark Urge, as hilarious as that could be.
"Nice to meet you Gale, my name is The Dark Urge, but my friends just call me The Urge."
"Right then. Pleasure to meet you..."
