In chapter 18,, Cap. 18, p. 65p. 62–68 Grettir fights his first creature, an reanimated undead or draugr of the man named Kárr inn gamli (Kar the Old). Kárr was there guarding treasure in his own funeral mound/tumulus from looters. Grettir triumphs using the sword Jökulsnautr (‘Jokul's Gift’, presumably passed down from his maternal great-grandfather Jökull Ingimundarson, son of Ingimundr Þorsteinsson who figure in the Vatnsdæla saga). Treasures are taken from the mound after Grettir's triumph, including an heirloom sword, presumably Kársnautr (‘Karr's-loom’). He has other successful adventures in Norway as well, killing bears and berserkers. He then has to flee Norway to go back to Iceland after he kills people for an insult in chapters 23 and 24.
