Sigma Octanus IV artifact

The Sigma Octanus IV Artifact is a Forerunner artifact first identified as such when it was on display in the Côte d'Azur Museum of Natural History on Sigma Octanus IV.

Description
The artifact was a crystalline object that contained a star chart embedded within its structure, with coordinates leading to the Soell system, where Installation 04 is located. Another set of coordinates lead to the planet Reach.

Background
The artifact arrived on Sigma Octanus IV in the form of a meteor some 60,000 years before human occupation of the planet. The human inhabitants of the planet later found the artifact and placed it in the Côte d'Azur Museum of Natural History.

During the Covenant invasion of Sigma Octanus IV, the Covenant attempted to seize the artifact from the museum, only to have the operation foiled by the SPARTAN-II Blue Team. Aware of the potential intelligence value, the SPARTANs took the artifact and placed a HAVOK tactical warhead below the museum.

Scans of the artifact were later given to Cortana and Dr. Halsey, who attempted to decrypt its contents as a form of language. During the Fall of Reach, Cortana successfully translated the artifact in a form of a star chart instead of a language, leading the and its crew to Installation 04.
