Battle in the Palaces of Chaos

“The palaces of Chaos are engulfed in the flames of war. Blinding flashes of magic illuminate the changing walls, which react to the battle by opening into portals or traps. Warriors in black armor fight creatures that resemble living shadows. One of the fighters rides a demonic horse whose eyes blaze with blue flames, slashing his opponents with a sword sparkling with primordial energy. The space around them is unstable: parts of the floor collapse, staircases turn into snakes, columns disintegrate and reassemble. In the distance you can see the central tower, where the source of Chaos' power is rumored to be stored.”
