A cinematic close-up of an otherworldly warlock casting a cataclysmic shadow spell, radiating cosmic dread. Their robe is a living tapestry of gothic horror, woven with glowing silver and obsidian veins, its fabric shifting like liquid void. Sleeves writhe with skeletal hands wreathed in black lightning. Inky smoke explodes outward, forming a swirling vortex of shadow magic that fractures reality, revealing glimpses of burning galaxies and staring eyes. The background is a chaotic storm of shattered space, with dying stars and swirling nebulae collapsing into the spell’s pull. The warlock’s face is obscured by a floating mask of blackened bone and glowing runes, their eyes burning with violet and crimson supernovas. Ghostly whispers echo, forming glowing runes that disintegrate into ash. The atmosphere is thick with ozone and impending doom, a fusion of elegance, menace, and apocalyptic chaos
