Hrimfraxi was a small, almost insignificant planet in the main body of the Tabula Rasa Anomaly. The Romulans had an outpost on that planet which soon proved to be the setting of a major plan of Admiral Narok, whom wanted to capture a live Metar leader there.
The Mission[]
The Romulan mission leaned on invading a Metar outpost on the planet, capture its Colony Core to search for the resident Metar Ras and have it transported out by the Tal Shiar for interrogation. Previous attempts in doing so however resulted in many casualties among (mainly) the Romulans, as the Metar Ras fought to the death in order to avoid capture. On Hrimfraxi however, a fleet on Romulan Warbirds pounded the planet's moon, sending fragments of it towards the planet to land as meteors in order to devastate the Metar Hive, but the main Romulan outpost was right in the path of the incoming meteor storm, forcing its personnel to evacuate the base and relocate to a small back-up facility. Engineering teams loaded as many raw and processed minerals into Armed Personnel Carriers which had to be escorted to the back-up facility safely, after which the Romulans could build up their base and proceed with their main objective.
