On June 8, 2557, the Taurokado arrived at the Korinth Prior system with Fireteam Apollo. There, they began to scan a large debris field and several Forerunner structures within. Evidence was found to suggest that the UNSC Spirit of Fire was there but did not survive the catastrophic event that took place there.
The Taurokado eventually encountered a Covenant remnant Battle Group. Apollo engaged several Type-31 Exoatmospheric Multi-role Fighters in Broadswords, before falling back to the prowler. The Taurokado released a sensor buoy and then fled.
