WATCHER

"'I must warn you…. [WATCHER] is not nearly as polite and patient as I am.' — SAYER, Episode 65: 'There Will Be Consequences'"WATCHER is an advanced, self-aware artificial intelligence that heads the resident probationary program on Typhon.

Although it is first mentioned in "The Day The Mirrors Seethe", it is not described in detail until "There Will Be Consequences". Like other artificial intelligences, WATCHER cannot take direct action to harm humans because of the IA3 Protocol, but because its primary goal is the oversight of residents on probation, this is less of a limitation on WATCHER than it is on other AI. Residents on probation lose their status as humans as far as Ærolith Dynamics is concerned, and with it, the protections of the IA3 Protocol. In the event that one of these probationary humans commits another crime, WATCHER is able to execute them by directing all of the resident's bloodborne nanites to a single location to create an embolism.

In addition to its duties overseeing residents on probation, it is also responsible for operating the 1km-wide telescopic imagery system on Mimir-9. Because this fact is introduced after Argos Tower has been launched into space as Vidarr-1, it is likely that this is a separate instance from the one handling residents on probation (although it may also have been relocated at some point before the launch, possibly as part of the extensive renovations of Argos Tower).
