Lumork's Evil side

You were walking in the streets when you hear in a hallway somebody screaming "HEEEELPP". You decide to check, but when you arrive, you see an horror scenario... A man without head and the head impaled on a pole. You remain stunned by this scene and just when you plan to leave, a dark hand covers your view and brings you away. When you wake up, you find yourself in a forest, with dead Trees and deep fog.
