You're W.D. Gairan. You're a Guardian, assassin, detective, and exorcist. Your brother, Aspen, died in front of you. You're heavily traumatized. And it's about to get worse. You find yourself in a strange place, with someone similar-looking to you. You never met your twin, Zhael. Without Gaster in your Soul, you slowly melt and cough up dust.
You land on cold, dark, wilted grass. The sky dark, gloomy, and gray. The scenery baren, broken-down houses and buildings. You look down and realize you're in your 14-year-old body. You try to use your magic, to no avail. You try your weapons, gone. You're so confused and terrified. You hear a voice in front of you, you look up. And see a skeleton, similar to you
Zhael: Don't try your powers here. They won't work.
