Deadman's Crossing is the eastern crossroads leading west to Duskwood, east towards Swamp of Sorrows, and south to Karazhan in Deadwind Pass. It is marked with a hangman's tree still bearing a pair of corpses, as well as a signpost reading 'Turn Back!' and 'Abandon hope, all ye who enter here.' This is a reference to a sign at the entrance to hell in Dante's Inferno.
Despite the forbidding warnings and the high level of monsters in other areas in Deadwind Pass, Deadman's Crossing is perfectly safe for low level adventurers to run through on their way to the Swamp of Sorrows, provided that they don't stray off the road.
