When the Advent began, Drew Michalik was working in a top secret facility in Washington, D.C. When all electronics simply ceased to work and blue screens appeared before him, he gained access to a mana interface and a number of crystals called xatherite. Utilizing these xatherite, he gained the ability to cast spells. Now alone and in the dark, he must battle through the bunker turned dungeon in a desperate bid for survival. But getting out is only the first of his many problems in the changed world, as Drew struggles to survive and keep himself, and the rest of humanity, safe through the anarchy.
