It's actually kind of awesome to start a multiplayerr session where everyone is a Tav, but you draw straws as to who plays the Urge. It'll be clear sooner than later - but fun nonetheless.
Oh, I’m doing one better. I’m going to play a game with three friends who know nothing about this game. I’m going to be a Dark Urge necromancer, I’m going to lean into it hard, and I’m not going to tell them. They can just figure that out on their own.
They won’t mind. I have been DMing for them for years. They are very used to me playing the villain and I’ll do it in a way they get a kick out of.
