Cornelius' Ring is a client loot item that Garrett is commissioned to steal by Orion in Chapter 2 of the game. It is a gear shaped ring made of an unknown material. In reality the ring is a key. When used in conjunction with the Ritual Book, it creates a conduit to channel Primal energy.
It is worn by Cornelius in the ritual in the prologue.
- It bears the mark of a gear similar to the Mechanist order, but may be linked to the Keepers.
