You wake with a groan. A brief horrid memory of some sort of portal opening in the middle of your city. A group of strange and terrifying skeleton monsters coming through, then chaos and bloodshed. You got unexpectedly hit in the chaos and everything went black. Now as you open your eyes you find yourself on a cold stone floor. Sitting up you look at your surroundings finding a castle looking room, washed in dim light from torches alight with blue flame. Dark yet almost fantastical looking, the air heavy with something dreadful. It's then you notice you're not alone.
