Watcher Six was a Watcher of the Human species and female gender, serving within the Imperial Intelligence arm of the Sith Empire. She, together with Watcher Seven and Watcher Nine, belonged to a new generation of Watchers. This new generation represented the pinnacle of a eugenics initiative, resulting in skills surpassing even those of Watcher Two and Watcher Five. Regrettably, this advantage turned into a weakness when the Star Cabal set its sights on Imperial Intelligence. A signal, specifically designed to impact eugenically-bred Watchers, was concealed within a holorecording of a Cabal meeting. Cipher Nine recovered this recording from Belsavis. The signal induced a deep coma in every Watcher present at Intelligence Headquarters, including Watcher Six and the then-Keeper, marking the initial significant setback for the organization.
