Hey, Im GMing a Rogue trader game were starting to get towards the climax (finally), and I thought it would be cool to end it in a bang. I remember a long time ago that there is a 5th demon god, one the others don't like to talk about. So, I figured it would be cool to see the Emporer and Primarchs wake up and the Imperium, Chaos, and All the Xenos team up to stop this god. I was wondering is anyone knows the gods name or details about him?
