Mysterious ancient artifacts from the early days of desert-choked Osirion count down the years until a rare planetary conjunction that will align Pathfinder’s world of Golarion with the hostile planet Aucturn, allowing the ravenous hordes of the Dominion of the Black to surge forth and harvest the brains of the Inner Sea, remaking the world in their terrible, alien image. Doomsday Dawn takes players on a decade-long journey throughout Golarion as they attempt to understand and defeat the otherworldy menace and avoid utter catastrophe in this 96-page softcover collection of seven multi-encounter scenarios designed to introduce the Pathfinder Playtest rules in a guided shared playtest experience coinciding with regular surveys and feedback from players just like you!
