Unidentified ancilla (Shield World 0459)
From Halopedia, the Halo wiki
- "Security barrier breached, high order infection detected, unidentified alien intrusion detected, initiating Stage 3 Defense Protocols."
- — When SoF enters the Shield World
An Unnamed Forerunner AI was on the Flood-Controlled Shield World.[1] It is unclear whether it is in charge of the whole Shield World or just the Cleansing Rings When the Spirit of Fire went into the underground section, it detected a "high order" Flood infection and an unknown alien intrusion. Once he detects these he initiates "Stage 3 Defense Protocols", which included activating Sentinels, cleansing rings, and Super Sentinels to clear away the Flood and the "unknown alien intrusion". Every time the Spirit of Fire approaches a cleansing ring it will say "Decontamination sequence commencing"
