A Relic is a Forerunner structure found in Halo Wars, they hold the keys to the containment doors, and thus can be used to release Flood upon an enemy. They must be garrisoned with troops to release the seal. They can only be found on the multiplayer map Release.


  • It is currently unknown why the Forerunners would build a way to ever release the Flood. Though, it is possible they were built before the war against the Flood started in full scale. It is possible it may have been for research purposes on species.
