The Faerie's Champion setting.

Cool bullshit:
Crumbling ruins with old library
Ghost city (Rome? Pathfinder + Neoquest inspo)
Trash dump where monsters live
Spooky forest where monsters live
Creepy carnival
The Wyrmwood
Faerie forests (one for each season)
Faerie graveyards

Even more cool bullshit:
Faeries, fey, unicorns, trolls, nymphs, satyrs, selkies and goblins
Graeco-roman monsters
Edwardian-Victorian fashion
Gothic horror
Werewolves, witches, vampires, ghosts
