The UNSC Edge of Umbra was a United Nations Space Command Prowler during the Insurrection.[1]


In 2503 the Office of Naval Intelligence discovered that Lyrenne Castilla, the second wife of then-Captain Preston Cole, was a high-ranking member of the insurgency. ONI suspected that Cole may have unknowingly or even actively collaborated with Castilla, and as such decided to have him returned to Reach for debriefing. Cole was confined to his quarters aboard his ship, the UNSC Gorgon, until the Prowler Edge of Umbra arrived in the Lambda Aurigae System. The Umbra then transported Cole to Reach.
