The ancient fire demon Surtur uses the grudges the Vanaheim have against Asgard to inflame a war that affects the nine-realms. When Volstagg thinks Loki is part of it, a suggestion to imprison the trickster leads Thor to battle the Warriors Three. The All-Mother's connection to the Vanaheim causes them to lose their rulership of Asgard and Volstagg becomes the new ruler. He leads a war through much of the nine realms. He tries to give a pardon to the All-Mother but they refuse, saying the people's trust do not match Volstagg's. Later, Surtur's forces are defeated thanks to Loki and Volstagg steps down to rule only over his family once again.
