The Resonance of the Void-Heart

A triad of obsidian monoliths stands on a floating island of translucent rock, surrounded by the shimmering silver mists of the Astral Sea. In the center, a jagged rift pulses with violet energy, pulling nearby debris into its hungry maw while emitting a discordant hum that vibrates in the marrow of your bones. Faded chalk circles and piles of ash indicate a ritual gone wrong, and the air feels heavy with the scent of burnt sandalwood and ozone. Brass rings encircle each monolith, capable of being moved vertically to tune the strange humming to a specific pitch.
