A dark abyssal chamber with a cracked, glowing red floor and tall pillars etched with eldritch runes. A central altar emits blue energy, beneath a red vortex with ghostly figures.

A vast, dark abyssal chamber deep underground, with jagged obsidian-black stone walls and floor cracked with glowing blood-red fissures pulsing like a heartbeat. Towering warped metal and jagged crystal pillars etched with glowing eldritch runes rise on either side, some dripping iridescent ichor pooling on the ground. A central altar made of fused bones and shimmering blue-purple aetheric veins, with a swirling crystalline vessel of chaotic void energy in its core. Eerie phosphorescent fungi casting faint green light on rough walls, wisps of shadowy tendrils creeping across the cracked floor, and thick smoky mist curling in the air. Above, a swirling vortex of shadow and flickering flames with ghostly twisted faces and limbs barely visible in the darkness. The atmosphere is ominous, mysterious, and magical, with glowing runes and dark mystical energy illuminating the scene. See more
