Yaawdet Maw (building)
The Yaawdet Maw is located at the former site of the Reitaghal ra Yaawdet Academy for Scholars of Magic and Science. While the vast majority of records have been lost, it is widely thought that the Maw formed while experimenting with an obscure spell that could transmit thoughts across a room. What resulted was a massive portal appearing on the ceiling of the tallest research tower, immediately filling the laboratory with red sand and suffocating everyone inside. Within minutes, the entire Academy was overrun as the sand crashed through walls and toppled buildings.
Attempts to close the portal have been unsuccessful, with local rulers having to conscript hundreds of ditchdiggers to contain the ever growing pile. Soldiers guard the perimeter against the horrifying monsters lurking beneath. Despite the danger, it is a popular spot for adventurers; the lost knowledge from the Academy is invaluable, and powerful relics from a land far away have arrived with the sand.
