D&D 5E: Brahnamin

Preamble

In the City of Swords, a dark alley is the scene of a vicious murder. A giant of a man is slain by a slighter figure from the shadows. A delicate hand drags a heavy hammer up from the cobbles. Teeth flash in a feral grin. A red fox melts into the night.

In the lingering dark, the body of a god lies broken on the ground. Mjolnir is taken. Ragnarok has quietly begun.

Premise

That Ragnarok is not a single great battle, but a long toppling of forces.
