The Soul Lens

An immense, ovate crystalline lens measuring six feet in diameter, suspended by cold iron chains above an elaborate obsidian floor. The floor is etched with an intricate, glowing map of the Ithilian Forest. The crystal is shot through with veins of emerald energy that pulse like a slow heartbeat. When the lens is manipulated by its master, it filters the spiritual resonance of the world, manifesting the life force of every soul within its range as a flickering pinpoint of light upon the stone below.
