Fermion

"Gamma Station, this is Fermion RSO. Unconfirmed report of an in-system slipspace rupture."

— RSO Fermion transmitting its early warning to Gamma Station.

Remote Scanning Outpost Fermion, also known as Fermion RSO, was an outpost in the Epsilon Eridani system designed to detect incoming threats to the Reach military complex.

Service history

Fermion self-destructs as several Covenant ships pass nearby.

Fermion RSO was active in the Epsilon Eridani system in the later stages of the Human-Covenant War. Following the battle of Sigma Octanus IV in July 2552, UNSC Fleet Command (FLEETCOM) began transferring experienced officers to RSOs throughout the colonies in order to ensure that their crews were operating effectively following the Archimedes RSO's misidentification of a Covenant fleet that had nearly resulted in the destruction of Sigma Octanus IV. As part of this, Chief Petty Officer McRobb was transferred to Fermion, where he spent the next three weeks helping the crew brush up on their maths to better-interpret slipspace probe data.

At 0447 hours on August 30, 2552, Fermion's slipstream probes detected a gargantuan signature of over 300 Covenant starships entering the Epsilon Eridani system. Prior to identifying the transient slipspace contact, it attempted to initiate the Cole Protocol. However, the station's science library (which contained every UNSC Astrophysics journal) was offline for repairs and could not be erased with the viral scavengers. Fermion alerted FLEETCOM and the last order CPO McRobb gave was to lock out the fusion reactor safeties and flood the reactor with deuterium, triggering the station's self-destruction.

Known crew

The following individuals were among the station's crew at the time of its destruction on August 30, 2552. All were killed when the station self-destructed.
