Lake Donigarten is home to the twentieth house, Sel'rue, who controls the massive fields of mushrooms and rothe herds that feed the majority of the massive City of Spiders, Menzoberranzan.

Their matron claimed the house in a controversial move after Freth narrowly failed to destroy them two years earlier in an all-out war.  Previous, Sel'rue occupied a far smaller house in the commons near the West Wall, but a house in the Upper Third should suffer no such disgrace—as either a poor house or a target.

There are 278 drow and 166 slaves attached to Sel'rue working the Donigarten on a daily basis.  Roughly 330 of them have formal combat training and can readily rise to protect the city or their house on a regular basis.
