It appears to be slowly leaking in real time lore showing how SIVA is getting released leading to RoI release. Owl Sector appears to be an Intel division in the tower/city, but not under the vanguard. So far it has ID'd four members: Shun, Quista, Berriole, and Ram (full name unknown so far). Berriole went to the dust palace and found a research lab that Willa bray (invented engam decrypting) and a dr shirazi used during the golden age. It appears to be the source of the infection. The also keep mentioning "Dawm Calamity". The way they refer to it, it sounds like a previous event, possibly the containment of a previous contagion release? They kept expanding the lab notes with new info every few hours. Pretty cool spin on the lead up they did on HoW/TDB.
