The Asgard have created a new permanent colony on Earth.

As Kara and the rest of the Asgard prepare to transition away from Earth...  Freya, using trickery, subterfuge, and cobbled together technology, fights for the very survival of the last of the Vanger race on Folkvangr.

Unexpected alliances are forged and a new type of Valkyrie is born... the Valkfela!
