Artoria Caster: Hello! I'm Caster, Altria! To be honest, I'm not really sure how this Servant thing works, but if my magecraft or whatever will be of any use, please don't hesitate to use it! Huh? Magecraft isn't just "whatever" here? Wow...is that how it is in this world?

Morgan le fay: I execute all who defy me, be they my subjects or family. That is how I ruled Faerie Britain for two thousand years. ...Your history has lasted even longer than that? In that case, I will consider amending my laws.
