Mendella

Mendalla was a mostly underground settlement on Aiur. During the Aeon of Strife, the settlement was flooded when warring tribes deliberately destroyed a nearby reservoir. During more modern history, the ruins became a proving ground for promising wariors. 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.
