Hardigan Ironjaw is an Ironforge dwarf of the Explorers' Guild and was part of the Thor Modan expedition. The Guild thought it was a good idea to send him to Northrend. Hardigan believed he could find evidence of his race's ancestors in the hills, and uncover truths about their early culture. He believes the Titans placed dwarves in Northrend, after they'd finished creating them. It was an experiment to see if they could survive on their own. The dwarves not only survived but flourished, spreading southward and into what would later become Kalimdor and the other continents.
