A massive, semi-eldritch sea creature resembling a fusion of a kraken and a demonic god. It has too many eyes scattered irregularly across its flesh. Its body is covered in iridescent, oily skin with black and deep sea-green hues. Tentacles writhe endlessly, some covered in barnacles and abyssal runes. Its central "head" is crowned by a halo of bone spines, and an open maw shows rows of translucent, jagged teeth. Its presence feels like it's devouring your sanity. No humanoid features. Background: abyssal ocean darkness, no visible surface, faint glowing particles drifting around.
