The Dead Swamps of Keltor rest creepily in the south of Radroz. The swamps take their name from the ancient lich Keltor whose magic was so powerful that it literally killed the land. The dead swamps are generally avoided by most travelers as they are difficult to cross (impossible in some places). The stories go that those who die in the swamps are unable to enter the Gray Planes and are forced to return as undead creatures.
