Nyx'Gorth - The Obsidian Wretch

A colossal creature with a jagged obsidian exoskeleton, covered in glowing runes. Its body is a terrifying mix of massive limbs and multi-jointed claws, with a hollow skull head emitting a sickly green glow. A veil of black mist surrounds it. Its form appears unnatural, with the ground cracking beneath it as it moves, distorting space. Its silhouette exudes cosmic horror and immense power, with an eerie, decayed look."
