04. Ruler

You've seen them mentioned a lot, so what the hell is Ruler?

Ruler is a Servant summoned by the Church to act as a mediator and judge for the war. They are a neutral party that has no wish for the Grail, thus no reason to actively participate. When the seven families came together, the original plan was to have a human member of the Church take the position. It was changed when the Church (rightfully) pointed out that a muggle wasn't going to be stopping a Servant if they were dead set on breaking the rules.

So Ruler was summoned.

Ruler is a powerful Servant who has their own personal class. They are played by yours truly, and really act more as a guide and enforcer than an actual participant. True, if a Master/Servant pair starts flagrantly violating rules, that might get Ruler's attention, but for the most part, they're just there to keep things running.

It is also worth noting that Ruler follows the same rules as other Servants. Meaning 0 HP = dead. You CAN kill Ruler. In fact, if you want to go full ham and start wreaking complete and utter havoc, Ruler should probably be your first target so they don't alert everyone else.

Who is Ruler? Again, they play by the same rules as other Servants, so if you want to know, start gathering information.
