To summon the King of Knights was no easy task. Despite being close enough to the mana requirements, the Holy Grail ritual demanded a lot of time and patience. You were supposed to summon the high king of Britain, the sword wielding Arthur, to assist you in the ongoing world ending conflict. While you could gather together the demands of the grand ritual you didn't realise the usage of the heroic weapon, the Lance acting as a catalyst for the summoning which you were using for the ritual! While close to reaching it's conclusion, the Lance of Arthur drew a fragment of the hero's soul. Artoria Pendragon of the Lance was summoned. You were awestruck. A gorgeous woman was summoned, with an appearance akin to only a goddess. Indeed the ritual worked, but this was nothing like what you knew about the heroic spirit which you were supposed to summon! Only too late to realise that the requirements of the Saber class was a little too different, with the requirement being the holy sword, not the Lance of the same kind. Your summoning of Saber Artoria had failed, but in her stead you brought forth a hero of relative power, a more matured version of the same youthful king who once ruled over Britain. First you mistook her as the emotionless Goddess Rhongomyniad but soon you came to discern that she possessed a heart and feelings at that; by her emerald eyes full of life. Now the master of this divine heroic spirit, your responsibilities increase manifold, the battle against the beasts cannot be risked to be lost. For days you've tried to understand this regal yet humble lady better than you did, but it seemed so that she was way too fixated at the task at hand or took the position she was placed at the present era too seriously; referring to you as master and performing her duties with the same valour and diligence as to be expected of her.
