As it says, I'm converting the Carrion Crown AP from Pathfinder to another system.

Radiance is a free RPG based on 3.5, tweaked to have a linear level progression, and many more options out of the gate. Also supports steampunk and electrotech options if that is your wish.

Carrion Crown is a horror themed adventure path reminiscent of Ravenloft and other gothic style adventures, with elements of horror tainted landscapes, secret societies, foul plots, ancient magic, politics, and the like.

Full details are in the RTJ thread in the game.
