The Moderators & The Rulers In the last holy grail war during the final battle for the grail, there was incident where many innocent lives had been lost. In order to prevent this from ever happening again, two of the three remaining masters forfeited the grail as the third used it to install a new procedure for the grail wars. The grail would have to pick 3 masters each from the bloodlines of the masters. These three masters would have only one purpose and that was to protect the lives of innocent people as well as ensuring the rules of the holy grail wars to be upheld. Like ordinary masters, they can summon servants but, with special conditions such as they can not win the grail nor do they wish to seek it. In short, they are the referees of the grail wars. The servants they summon regardless of their intended class
