Chieftain Gunthor is the leader of Gunnarsgrunn. He is the father of Gudrun and the grandson of Gunnar, the founder of the village. He places great emphasis on honouring his ancestors, particularly Gunnar, who he frequently praises. Initially he believes this means being the raiders that his ancestors were, treating the village as a war camp rather than a peaceful settlement. However, through the combined efforts of Gudrun, the dwarven poet Dororan, and an adventurer, he is convinced that they are actually settlers.
After Gunnar's Ground, it is possible to have a drink with Gunthor. He and Haakon will say "skål", and the player will say cheers. A skål is a Scandinavian toast of friendship usually offered when drinking. After completing Glorious Memories, the player will say "skål" as well.
Chieftain Gunthor used to be attackable at level 29 but he became unattackable along with the release of the quest Gunnar's Ground.
