Shallazad, The Abbey of Silent Bliss
From ODRA
Shallazad, the Abbey of Silent Bliss, stood over 200 years ago, (c. 1290 DR) when the Mere of Dead Men was a rich farmland. An eruption of arcane energy from the nearby Sword Mountains destroyed the area and turned it into the cursed swamp it is today. all that is left of the abbey itself are ruins. However, when the sun sets, the a ghostly visage of the abbey apparates into existence through the mist realms and brave adventurers may enter; they only have until sunrise to leave or face being trapped within its walls until the following sunset.
