Under the scorching sun of a medieval desert, a colossal humanoid spectre of green and purple light rises above the horizon. Its body of fluctuating energy is surrounded by small sandstorms that swirl around it, distorting the sunlight into blinding flashes. In its wake, the desert seems to change, the dunes morphing as if alive, and ancient rune markings gleaming upon the stones scattered on the ground. The warriors who dare to face it, barely visible in the distance, are dwarfed by its grandeur.
