A towering, lithe humanoid boss with obsidian-black, jackal-like head and a body covered in shimmering scales and writhing, bioluminescent tentacles emerging from its back and sides. Ancient golden jewelry hangs from its neck and wrists, and its eyes glow an eerie green. Instead of a mouth, the lower face splits open to reveal rows of tiny lamprey-like teeth, constantly shifting and pulsing with eldritch energy.
