Its story
What it looks like
A wet, lidless eye the size of a wagon wheel, suspended in a cage of black iron hooks.
Its iris is a pinprick of silver light surrounded by rings that resemble tiny, screaming mouths.
Why it is here
To torment captives, break their will, and provide grim amusement for the Kythons who oversee the torture.
Who made it
Velstrac torturers of the Shadow Plane, who fashioned it to break prisoners and amuse the Kythons during long stretches of grim routine.
Lore
Velstracs claim the eye was made to reveal the pain hidden in a victim's memories.
In practice, it is a crude but dependable instrument of psychological torture. Kythons sometimes activate it simply to see what a captive will do when confronted with a cherished memory turned against them.
Where it is found
The Shadow Plane and other planar sites used by velstracs, especially torture chambers, galleries, and prison corridors.
