Quantum lock

A quantum lock was something capable of separating a certain area of space from entangling with the rest of space-time. This kept events in the contained area from tearing apart space around the affected area.

In 2382, Juel Ducane and Jena Noi established a quantum lock around the third moon of Rakon IV in order to stop the battle between various Temporal Cold War factions from tearing apart space-time.
