The center of Osgiliath(ne, se and w)

You are walking over the great island that forms the center of Osgiliath. A mighty stronghold this must have been in days of old. Only crumbling stone remains now, a mere ghost of the past.
The citadel of Osgiliath stands east of here, and you think you might be able to enter if you head southeast.
A foul brown haze covers everything.
The only obvious exits are northeast, southeast and west.
