Orion complex

The Orion complex is a large nebular complex in the Orion Arm of the Milky Way Galaxy. The nebula was once home to significant Forerunner activity, including their homeworld Ghibalb, located at the outer edges of the nebula, as well as the triple star system housing the homeworld of Bornstellar Makes Eternal Lasting and his family. 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 fifty thousand years.

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.
