The Eye of Dur

 is one of the unused Relics from Gauntlet.

The Eye of Dur appears to be the beta version of the Demonic Effigy. They are almost an exact copy of each other right down to their abilities and description.

Lore
There is an ancient evil, the astral corpse of which is resting in the aether. This dead god is worshipped by a cult whose ultimate purpose is to resurrect their supreme deity.

The spawn of Dur waits on the other side of the veil, eager to claw their way into the realm of mortals to wreak havoc.
