Valkyries are one of a host of female figures who choose those who may die in battle and those who may live. Unfortunately, some of them become corrupted by dark powers of Helheim and reduced into monstrous shadows of their former selves and infested Northgard.
Valkyrie are aggressive and will attempt to Decolonize any territory next to theirs.
Rig and Halvard first encounter one of Valkyries in Chapter 3. Delighted at first, Rig wanted to propose alliance with her, but is stopped by Halvard who noticed that she had been consumed by corruption and beyond saving.
