ONI Ilex Facility

The ONI Ilex Facility is a classified military black site operated by the Office of Naval Intelligence as part of the Zeta Halo project.

History
The Ilex Facility was involved in Operation: ECDYSIS, a facet of the ongoing study of Installation 07 by the United Nations Space Command. Situated atop an icy mountain on an unidentified planet, it was involved in studying materiel and technologies discovered on the ringworld. Some of the structures analyzed at the Ilex Facility included structural samples taken from Installation 07, which were able to yield a number of discoveries in mineralogy. However, despite active research, the base was unable to replicate the effects of reformation as demonstrated on the ring, due to being unable to reproduce the method in which Forerunner technology turns raw materials into useful structures even despite a number of workarounds implemented to boost the base's electrical power output to a fraction of that needed for full-scale testing.

Ultimately, the base's staff were unable to progress as rapidly in their understanding of Installation 07 as the researchers on the shield world Trevelyan were, though they remained hopeful that future discoveries may be able to assist humanity in restoring the multitude of colony worlds glassed by the Covenant during the Human-Covenant War.
