From itch.io: Journey to the town of Thornbrook where a hole has mysteriously appeared for no obvious reason and the townspeople want it gone. Each has their own tales of items disappearing whenever that hole has been present. After a few stout and foolhardy folks made their way into it and never came back, nobody local is willing to venture within. If the heroes expect to be able to leave Thornbrook, it seems the only way they can go is down. Beyond their Grasping Master was not made for any specific ttrpg system, but is suitable for pretty much any Fantasy setting and ruleset.
