A drowned king sitting upright on a rotting throne on the seabed, a crown of rusted iron resting crooked on a bare skull, with schools of pale fish skeletons swirling around him in slow circles. Ribbons of tattered purple cloth float upward from his shoulders, and dim shafts of green light fall from the surface far above onto a ruined hall of coral covered columns. Tiny glowing jellyfish drift between the pillars like lanterns. Deep green, ink blue and tarnished gold palette. Dark fantasy underwater illustration, soft volumetric light, fine decay detail, vertical composition.
