While the Watchers were mostly interested in keeping their existence secret from immortals, the 2000 movie
Highlander: Endgame revealed that a breakaway sub-group made an exception for immortals who wanted to seek refuge from the Game and leave the world behind. To this end, these Watchers provided a secret place Sanctuary where they would place immortal volunteers into a coma-like state and care for them afterward. By providing this service, these Watchers meant to ensure that the Prize would never be won because there would always be at least some immortals still alive. There must always be two. It is unclear if the immortals who joined the Sanctuary knew they would be placed into a state where they would not be able to change their minds and ask for freedom unless awakened by someone else. It is also unclear if they knew that the Sanctuary was run by Watchers or believed it was an independent organization and didn't know about the larger Watcher order. In
Highlander: Endgame, an immortal villain named Jacob Kell invades the Sanctuary and kills the immortals who are there. Matthew Hale, the Watcher who supervises the facility, is desperate that the Prize must not be won and decides to kidnap new immortal "volunteers" to maintain the Sanctuary's purpose. Kidnapping Duncan MacLeod, he comes into conflict with Joe Dawson. Later on, Joe shoots down Hale when the man attempts to kidnap both MacLeod and Kell and force them both into the Sanctuary. It is not clear if Hale's death meant the end of the Sanctuary. In the theatrical version of
Highlander: Endgame,
Methos refers to the Sanctuary as existing on holy ground. In the TV series and previous films, it was said immortals followed a traditional rule that fighting on holy ground was forbidden. The movie
Highlander III indicated that fighting on holy ground would lead to unforeseen consequences but no other story indicated this and the movie also contradicted canon established in previous films. In the season 5 episode "Little Tin God", Joe told Duncan of a legend that two immortals killing on holy ground caused the destruction of
Pompei, but admitted there was no evidence of this or anything similar happening throughout the history of immortals. Despite this, a number of fans criticized
Highlander: Endgame for showing Jacob Kell killing other immortals on holy ground without any consequence and didn't care for the implication that it was simply a rule that others (including evil immortals) followed out of tradition, especially when the movie then showed Connor and Duncan being unwilling to kill Kell when he is on holy ground himself later. To simplify matters, the DVD and digital editions of
Highlander: Endgame removed all reference to the Sanctuary being built on holy ground. ==References==
