At the Beskir stronghold, leaders who distrust one another accept the same arithmetic: no clan or realm survives alone. Kaya, Tyvar, Inga, Fynn, Sigrid and Arni carry the Sword of the Realms toward Halvar while demons, draugr and displaced monsters pour across Bretagard. Elves arrive under Harald not as conquerors, but as the reinforcement the human line needs.
Halvar takes the sword and asks for time to close the passages. The coalition holds the bridge. Valkyries descend with Niko Aris, Tyvar pins Varragoth's attention and Kaya uses the assassin's precision she once wanted to leave behind to kill the demon lord. Halvar then pulls the realms apart, ending the Doomskar before the temporary battlefield becomes permanent ruin.
The survivors inherit years of scattered dangers, but also proof that old enemies can choose cooperation. Tyvar decides to explore the wider Multiverse. Elsewhere, Vorinclex overpowers Esika and fills a vessel with sap from the World Tree, the basis of the gods' Cosmos Elixir. He returns to New Phyrexia with the sample, revealing Kaldheim as reconnaissance for a much larger invasion.
