The Strange The Dark Spiral Monte Cook Games by Monte Cook Games instant download after payment.

A mundane-seeming crime masks a sinister plot—and sends characters racing across a dozen realities in a bid to save the Earth!
Spiral dust is an incredible high. Wonderful. Transcendent. Orgasmic. That’s what users claim, eyes wide to reveal blue fractals instead of irises. Spiral dust addiction is on the rise. But why? Who is the Dustman who deals this strange substance from the shadows? And why do heavy spiral dust users tend to disappear without a trace?
The Dark Spiral is a multi-part adventure for The Strange. Player characters are tasked by the Estate, a secretive organization pledged to protect the Earth, to shut down a local dealer of spiral dust. Their mission takes them farther than they expected when the trail leads to alternate, limited worlds called recursions where the rules of reality are different.
Game masters can intermix secondary Estate missions (in any order) with the main story arc of the adventure to create a mini-campaign. The Dark Spiral introduces players to the wonders of translating between alternate worlds of The Strange and showcases the narrative structure of the game. And it includes six pages of awesome “show ’em” illustrations to pull the players right into the action!
In addition to introducing new recursions not covered in The Strange corebook, The Dark Spiral offers new creatures, characters, and items to add to any campaign.
