The Alimbic Cannon is a device created by the Alimbics to open dimensional voids. The cannon uses the Octoliths to operate, relying on them for power and coordinates. The Alimbics used the cannon to send the Oubliette, along with Gorea, into the Infinity Void. The cannon sends out a number of blue rings when activated, creating a reigon of space that opens into another dimension. The physics of the cannon are unknown.
