The Aesir is the pantheon of the ancient Scandinavian gods who play a role in Scion. Renowned for their bravery and honor, they are unfortunately bound by Fate, as they are supposed to die during Ragnarok, and have become obsessed with the potential for its arrival since the return of the Titans. Their Overworld is a fortress known as Asgard, which is surrounded and besieged by Muspelheim, the Greater Titan of Fire. Their Underworld is the frozen land known as Helheim, where dwell the unworthy dead.
