Something has shifted in Asgard. Odin is now on the move, and his Valkyries are riding and breakneck speed to lay claim to the souls of those lost in battle. Is the twilight of the gods at hand, or is there some other offensive that Odin requires the additional troops for? Is it even Odin, or has his blood brother Loki played some trick upon the Valkyries?
In any case, few angels are comfortable with pagan gods moving about the mortal real so freely and in such numbers.
