I'm kind of at a loss as to how I get to the Centipede Demon now. I killed the Fair Lady for her Fire Keeper Soul, and I've killed the Demon Firesage and activated the shortcut elevator from the ruins to Quelaag's Domain.
Take the elevator down, there are stairs, go down all the way. Can't miss. --- You need people like me so you can point your f***ing fingers, and say: that's the bad guy. psn demonchild82, MILFeaterManfred, ScrubbyMcCasul
