Act as a master dark fantasy artist with 10+ years of experience in horror illustration. Create a chilling portrait of a [SINISTER ENTITY] ruling over a [DESOLATE REALM], blending [GOTHIC ARCHITECTURE] with [BIOMECHANICAL HORROR] elements. The figure should have [GLOWING EYES] that pierce through swirling [TOXIC MIST], wearing a [CROWN OF BONES] fused to its [DISTORTED SKULL]. Surround the throne with [TWISTED SUBJECTS] in various states of [AGONIZED TRANSFORMATION]. Use a color palette of [DEEP PURPLES], [SICKLY GREENS], and [BLOOD-RED ACCENTS] to emphasize the unnatural atmosphere. Render the scene with hyper-detailed textures showing [CRACKED OBSIDIAN SKIN], [DRIPPING BLACK TAR], and [RUNIC SCARS] that pulse with forbidden energy. The composition should evoke dread through dramatic lighting casting [LONG SHADOWS] and [UNSETTLING SYMMETRY].
