I'd like to do a post-apocalyptic RP, based on what the vikings believed would happen after Ragnarok. Surtr and the fire giants of Muspelheimr washed the world with flame, and killed nearly all of the gods. What remained was a burnt world, with only a few small coves of life surviving. You are a creature of Midgard (either human, elf, dwarf, troll, or fallen Einherjar or Valkyrie), who survived the apocalypse, tucked away in a secluded meadow, surrounded by mountains. The world outside is a dark place, full of new evils, and there isn't enough to keep all of you alive in the meadow.
You must go out, reclaim the fallen world from the forces of Surtr, and find a way to restore all nine worlds, so that life may once again thrive.
