Unidentified Ascendency participant relaying Nurse Yugoslav's intelligence to Stockade and Houston.
Panford states that the information from the Eighteenth Floor reached Commander Stockade and Architect Houston "via a third party participating in the Celestial Ascendency" — and that because celestial messaging is secured, the adjutants do not know who the middleman is.
That unknown is the whole reason Architect Houston walks free: without the link, the case is only his presence in the castle plus his mother's involvement, which Opiee calls damning but circumstantial. It also means an active traitor or paid asset remains somewhere inside the warlord game — a loose thread the Live-Feed Blackout neutralizes without ever identifying.
The unidentified inside relay in the cheating conspiracy.
