The Orion complex is a large nebular complex in the Orion Arm of the Milky Way Galaxy. The nebula was once the nexus of Forerunner activity as the core of their ecumene. It was home to the Forerunner homeworld Ghibalb,[1] located at the outer edges of the nebula, the triple star system housing Molaetra, the homeworld of Bornstellar Makes Eternal Lasting and his family,[2] and the Capital, the seat of the Ecumene Council. The cloud itself is situated between 1,500 and 1,600 light-years away from the Sol system and is hundreds of light-years across. The complex contains several smaller nebulae, and many protoplanetary discs and young stars.[3]

Early on in Forerunner history, their nascent civilization settled twelve systems within the complex. Due to a series of novas triggered by early Forerunner experiments with stellar engineering near their homeworld, the entire Orion complex was brightened for the next 50,000 years.[1] The Forerunners relied on a defensive boundary known as the Maginot Line to keep the systems of the Orion complex safe from enemy assault.[4] During the human-Forerunner wars, human forces never came closer than 15,000 lightyears of the Orion complex.[5]

In 2558, Bastion was located in the Orion complex after having been moved from its original position at some point earlier. To protect the shield world from Cortana and the Created, 343 Guilty Spark moved it through a slipspace portal to an unknown destination.[6]
