The chapter about The Underworld in the core rules of KULT: Divinity Lost is just so painfully good. It is written in a way that you feel the emptiness, the echoes, the whispers in the labyrinth. And for some reason I can’t really get it out of my mind.
I think the prospect of portraying one of the Children of the Underworld is an interesting one. Sure, it will be hard to portray something alien and strange. But they have such a fascinating story and I think they could become very distinct archetypes.
So, if I would have a request of an official supplement it would be a book, or a stand alone game, where you play a Child of the Underworld.
I want to play as a Famaria!
