One of the four Pedestals of Death.
The Pedestals of Death are the four pedestals in front of Death's Door; the gate to the sacred Sanctum of Azriel.
Background[]
By inserting the Lever of Life into each one and spinning them, Connor was able to unlock the gate to the sanctum. When a pedestal was spun it would sink and the flame would go out exposing a red crystal on top. Once all pedestals were were lowered four energy beams emanated from the crystals on top converged together and shot a magic fireball at the door to Sanctum of Azriel opening it.
