A thousand meters beneath Northrend, the sealed environment made it extremely warm, and abundant groundwater allowed all manner of enormous, strange mushrooms to grow from the rocks.
The Empire of Azjol-Nerub was divided into two regions: upper Azjol-Nerub and the lower ancient kingdom of Ahn'kahet. Yet just how vast an area these two regions spanned was likely unknown even to Anub'arak, the former king of Azjol-Nerub.
