King of Depth

ultra-detailed illustration, dark fantasy style concept art, horror, intricate details, detailed line drawings resembling copperplate engravings or pen drawings, watercolor-like uneven brushwork. The creature is a humanoid monster featuring the head of a white squid and glowing golden eyes; it sits upon a throne, clad in tattered black robes and clutching a ceremonial staff fashioned from bone and a white murex shell. The throne itself is carved from white rock adorned with intricate Gothic-style relief work, its surface encrusted with barnacles. Pale, glowing deep-sea fish swim around the monster, appearing to revere it as their king. While the background is dim and indistinct, the symmetrical arrangement of massive, stately pillars reveals the setting to be a majestic throne room. The chamber is illuminated by shell-shaped light fixtures, and the contrast between the warm light they cast and the cold blue shadows serves to define the composition of this masterpiece.
