History
Utgard-Loki's magical prowess was so great that over the years he had on more than one occasion beaten members of the Norse pantheon in conflicts, including having fooled the Norse gods Loki and Thor with his illusions. Over time he gained a great deal of nephews, one of whom was the frost giant Habrok Icecaster, who would come to sit as one of his many jarls in Utgard.

In the, a group of adventurers from the city of Ravens Bluff on the world of Toril traveled to Ysgard in search of the legendary Well of Mimir. While passing through the layer of Jotunheim they encountered Utgard-Loki's nephew Habrok, out hunting with six friends, who told them of his uncle's power and greatness. They also encountered Torheim, a proxy of the Norse god Thor, who expressed wanting their help in a later scheme he was devising to utterly embarrass Utgard-Loki and offered them a coin to give to the Well of Mimir's guardian if they could slay one of Utgard-Loki's nephews.
