Chronicles of Khaldun: Crux of Eternity
Barony Aalsburg was once a notable town in the southwestern Sorrowfell Plains. According to The Tragedy of Barony Aalsburg, the gods were so sorrowful over the corruption in the barony that they cursed the place, causing it to become infested with undead.
This version of events is untrue.
Instead, Baroness Morana van Aalsburg survived the purge, and eventually became a lich. She presumably cursed the place herself, using the ruined town as a base of operations where she could research her own reanimation schemes in private.
It is now considered a cursed place, best left avoided.
Ellalas camps in the vicinity of Barony Aalsburg, contemplating the nature of sin as expressed through the endless tides of undead.
