The Final Countdown!

Mysterious ancient artifacts from sand-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 the heroes on a decade-long journey throughout Golarion as they attempt to understand and defeat the otherworldy menace and avoid utter catastrophe. This collection of seven multi-encounter scenarios is designed to introduce the Pathfinder Playtest rules in a guided, shared playtest experience coinciding with regular surveys and feedback from players like you!
