Well I totally missed it but Little English Halo Blog didn't. Hidden within the text of the latest Halo Bulletin lies this curious message from the Surgeon to the Coalminer (operatives for the Office of Naval Intelligence, ONI).
Here's the coded message (and here's the first message).
ENCRYPTION CODE: [CLASSIFIED]
PUBLIC KEY: N/A
FROM: CODENAME SURGEON
TO: CODENAME COALMINER
CLASSIFICATION: ELEVENTH HOUR [2/5]
SUBJECT: OVER THE FENCE
/FILE EXTRACTION-RECONSTITUTION COMPLETE/
SPECIES CANDIDATE//LINE RECORD 94:73:02:75
UNGGOY// Sensors at Balaho indicate stability, no off-planet transport recorded since Solipsis. Runners are claiming that Buwan has been abandoned as well, but we’re keeping our eyes on it anyway. Moderate Unggoy populations have been observed in Sangheilian systems at various intervals.
KIG-YAR// Eayn’s native population continues to grow and expand within reasonable governing parameters; its economic and social lines have stabilized in the wake of the war. Muloqt, Kaelarot, and Valyanop, the primary interplanetary colonial sites, all remain static, with little notable movement. There are rumors of mercenaries operating alongside a handful of more conservative Sangheili states, although that has yet to be substantiated.
SANGHEILI// Most intel here originates from ground contacts, but sensors have assisted with validation. The primary issue with the Sangheili is that of discordant cultural symmetry. It is difficult to assess military growth across several dozen active colonial vectors all with disparate political structures. Nevertheless, any and all visible military activity appears to be internecine in nature.
NOTE: A cluster of Sangheili frontier worlds saw a sudden and anomalous convergence of unregistered ships, largely cruisers of varying classes according to a handful of remote relays stationed nearby. By the time sensors were deployed, the ships were gone. The relays can’t assess numbers or strength, but the readings we have indicate that this wasn’t an expeditionary voyage or something tied to a single state. It appears to have been much larger.
