Mendalla was a mostly underground settlement on Aiur. It sits on the island of Brushfire and is connected to the mainland by strategically vital bridges. The area is rich in natural resources.
During the Aeon of Strife, the settlement was flooded when warring tribes deliberately destroyed a nearby reservoir.
In more modern times, the ruins became a proving ground for promising warriors.
During the zerg invasion of Aiur, a nest from the Baelrog Brood settled into the area, and only a combined force of protoss and terran troops was able to remove the infestation.
Terran forces later battled over the island of Brushfire, hoping to exploit its resources.
