The Swamp of Lost Souls is a location in Two Worlds 2. It is a large swamp with many curses imbued in the land. For one, the dead are constantly rising and slaughtering any one they can reach. Second, all who come through the swamp can never leave; a magical barrier bars anyone from leaving, but not from entering. There are rumors of a Witch luring people out and having the Undead kill them. The only speck of civilization is a small village.
A certain wizard has been known to have been able to leave the swamp alive.
