From WoWWiki

Khaz Modan is the name of the mountainous subcontinent containing the homeland of the Ironforge Clan, the kingdom of Ironforge (aka kingdom of Khaz Modan[1]), which is ruled by the Bronzebeard Clan. The dwarven kingdom was founded after the awakened dwarves ventured out from the ancient city of Uldaman. The continent was named the "Mountain or Mountains of Khaz" after the Titan shaper Khaz'goroth, thought to be the creator of the dwarven race. The mountains here are also called the Khaz Mountains.
