Giantbane War

The Giantbane War
A force of Fire Giants, supported by Hill Giants, ogres, and various evil humanoids, push from the south into Khazad Hurd. They hold much of the surface and significant parts of the Underdark until a relief army from Kytzvr arrives in secret and helps drive out the giants. The lack of support from Freeport irritates the Khazad.
