this is a world fallen due to spatial rifts opening on earth leading to other planets and dimensions, this world is plagued with an alien zombie virus and magical beasts and mutated creatures.
There's elves, demons, vampires, werewolves, magic, slimes, goblins, dwarves, dragons, the works.
there's also systems like certain novels I like and mutations like marvel or DC.
I hope you stick around for the ride.
