Ravenloft
Trapped in another world, each area of the world is its own little plane of existence, ruled by the baron! Vampires, ghouls, zombies, wights, undeads, witches, curses and no way out - DUN DUN DUUUUUN
Ravenloft is a campaign setting made of lofts and ravens...well, ok, it's a D&D campaign setting that threw away the shiny high fantasy heroism cliches and largely substituted them with 19th century gothic novel material. Ravenloft itself is a demiplane, divided into several domains each ruled by a different lord, inspired by traditional horror tales. The first rule of Ravenloft is not to touch anything, ever. It will kill you, rape your corpse and use your soul for thong underwear.
