Masters of the Unseen Tower
To the East of Gan Loren stretching all the way to the world sea coast, lies Bereth Logor. The land was once fertile and populated, until the Wizard Wars thirteen hundred years ago scorched it to barren wastes.
The aftermath of the Wizard Wars has left magic unstable in the area. Teleportation and scrying function erratically if they function at all. This area extends north from the coast and teleportation beyond line of sight is impossible, into the Pirate Isles.
The ruins of a number of cities still stand in the wastes, attracting treasure hunters and fools to their deaths, or glory. (One of these unnamed cities is apparently home to an underground population of Were-moles, as seen in the Misadventures of Lyrrin Kilomere and Carlos the Beholder.)
