The Lithic Chorale

Six obsidian pillars stand in a circle around a central stone basin within a damp, echoing limestone cavern. The air is thick with the smell of old copper and wet earth, while a low, rhythmic vibration hums through the stone floor. Each pillar is carved with a single prominent glyph that glows with a faint, pulsing violet light. Above the basin, a large stone eye is carved into the ceiling, its gaze fixed perpetually downward on the altar.
