Grugaran was an old and frail stone giant when he recovered the artifact known as the Crown of Obadai from human tomb robbers. He and his young lover had a plan to turn themselves into liches using the ancient stone giant artifact, so that they could rule over a reborn Nedeheim. Unfortunately, when Grugaran first attempted to use it, the crown killed his young lover. Now a heartless lich, Grugaran declared himself Dodkong regardless for his lost love and set about his goal. He gathered the displaced stone giant clans of Nedeheim and with them, he refounded the kingdom, calling it Cairnheim.
The Dodkong rules his kingdom through fear. He considers wherever he is feared as part of his kingdom and as such commands several hill giant clans and collects tribute from several human settlements in the region. In addition, should he choose to call upon them, he can also command several large tribes of orcs and hobgoblins to fight for him.
