Primal:Rift Gates

Rift Gates are devices that were created by the servants of Abaddon and Arella to make it easy to travel between the Nexus and the demon realms (and within the realms themselves). They are magical devices based around two large wheel-handles that can be spun up to very high speeds, generating power and allowing a 'rift' to form within the centre of the gates. The user may then walk through, as if through a doorway, emerging on the other side of another Rift Gate at a completely different point in Oblivion.

While Gates in the Nexus are always open and paired with specific Gates in each of the four realms, Gates outside of the Nexus can link either back to the Nexus, or to any other Gate within the same realm.
