Other than Borean Tundra where they attacked a Horde outpost the Kvaldir are our enemies because Odyn sends us to kill them. Odyn aided us so well that he only gave Aegis to us and not Skovald because we weren't late. Despite Skovald ignoring the shit out of the trials and making a mockery out of them (including sending the spirits of the ancient kings required for one of the trials to Helheim but that didn't seem to phase Odyn at all). Then watched idly as Skovald tried to kill us for the Aegis and used it during the fight. Blizzard forcing us to choose him out of all people over Helya, or even pick sides at all is shit storytelling devoid of any depth or colors other than black and white. Because Blizzard writers are incapable of these.
