Midgarð is ravaged by treachery. Ragnarök—the final battle—has begun.
The Gods, and the Jötunn giants see their destruction at the moment of their creation; neither can stop it.
With Loki’s betrayal, the Jötunn overthrow Valhalla—hall of the slain—and home to the Æsir, forcing the exodus of the gods and snaring “Óðinn’s chosen,” warriors.
Óðinn follows his trickster son to Vinland, to warn them of Loki’s plan to alter human destiny and pave the way for the Jötunn to survive their destruction.
Meanwhile, Thorfinn is working to honor his agreement with the First Nations people and leave Vinland, but an assassin’s attack sends Gudrid into premature labour, and when she regains consciousness, she’s horror-stricken to find baby Snorri missing.
On the shores of an inland lake, Freydis Eiríksdóttir betrays her kin.
A visitor urges them to journey to Leif’s southern settlement and into the caves, to seek Snorri and to stop Loki from his final task.
The way to the end is fixed; the spilt blood of kin conceals its outcome.
