Harongrand is a massive plateau of Morteban. It looms almost 9000' over the Tamoroc plains with cliff walls both steep and rugged. The plateau was settled by stone giants some time during the God Era. These giants were remnants of an earthen army that once served Geb. When Geb fled into the Underdark, pursued by angels seeking to send him back to Chaos, or imprison him, the army was ordered to break-up and scatter across the world. The stone giants that came to this area built a number of settlements, with the largest being Jofgried. They enslaved earth giants, Tungesti, and other tribal peoples and put them to work cutting four mountain roads up to the top of the plateau.
In the Horgon Era, Harongrand became territory of an even larger group of stone giants from the north. This northern foe was Cûngin-Zar. They fought costly wars to take not only Harongrand, but also Onvargard. The battles to reach the top of the plateaus resulted in the deaths of thousands, if not more.
