Alastor's game

A dark, monstrous figure with glowing eyes and red tendrils rips open its own chest, revealing a fiery interior, then transforms into a towering, winged entity with a skeletal face and a red, tattered cloak, standing over a chaotic scene of smaller creatures and burning structures, before the perspective shifts to a red, horned figure holding a glowing lantern that emits light and musical notes, as a green, monstrous hand reaches up from below.
