Demonio colosal emergiendo de un portal llameante en la Infraoscuridad

In the vast, cavernous Underdark, render an apocalyptic summoning gone wrong: a colossal, ancient demon tearing free from a warped circular portal in the stone floor, hauling itself upward through rippling, warping fire; its skin a molten obsidian and charred crimson, eyes like fissures of radioactive green, mouth open in an insane, world-shattering bellow that expels building-sized plumes of sickly green flame. Surrounding the demon are innumerable ethereal chains of shadow-smoke and black lightning — the Circle of Power’s bindings — snapping and unraveling midair, tendrils of shadow peeling away like torn fabric. The middleground seethes with hellfire storms, raining embers and ash, shattered stalactites and warped rock, while terrified Drow cultists in ritual regalia are flung backward by shockwaves, their arcane sigils flickering and burning. Convey the demon as pure evil incarnate, a force of annihilation intent on consuming everything it can reach. In the foreground, compose a demoralized party of four heroes slumped and hiding behind massive stone pillars: a grizzled dwarf male heavy-armored fighter, gaunt and furious, punching the wall in impotent rage; a hooded female half-orc ranger/rogue in her thirties, head in hands, despairing; a mid-fifties human male wizard, robes singed, standing behind and consoling a beautiful blonde female elf cleric who kneels, crying and praying, hands clasped, tears catching hellfire light. Capture intimate, human emotion against cosmic horror. Lighting: dramatic chiaroscuro with harsh rim light from green flames and molten portal, deep violet ambient gloom, volumetric smoke and godrays, reflective wet stone. Color palette: toxic greens, infernal oranges, obsidian blacks, bruised purples. Style: cinematic, richly detailed, high dynamic range, painterly-realism hybrid, epic scale, dynamic motion blur on falling debris, crisp character faces and armor, intricate rune textures, realistic fire and smoke physics, clean background, no speckled noise, no random particles, no visual artifacts, smooth gradients, no grain, no dust, no floating particles unless intentional, subtle, soft atmospheric haze (not particle-based). Framing: wide-angle, low camera near heroes for scale, deep depth of field, epic composition, high contrast, dramatic atmosphere, evoke dread, tragedy, and the moment before total rupture.
