From publisher blurb: What you have here is a toolkit to run adventures and missions in a world where shadowy groups seek to control powers beyond the scope of mortals. Where the devil isn’t just some ‘horned guy’ painted red, with a swishing tail. Lucifer is an entity which has been watching the world for a long time; he’s been making notes, taking names, and planning all sorts of fun activities for us. This book is focused on giving enough information to the GM. There are secrets a-plenty in here that players should never see, if you’re a player, I’d stop reading right now. If you’re a GM, then tell your player's Good luck, they’re going to need it.
