Artoria Pendragon

Artoria Pendragon or otherwise known as Arthur Pendragon, was the legendary King of Knights who ruled Camelot in Britain. During her childhood, before she became a king, Merlin setted up a challenge. Whoever pulled the sword from the stone shall become the King to rule Britain. However, this challenge was rigged for Artoria to win. Merlin warned Artoria that if she pulled the sword, she will meet a terrible end. Artoria accepted the fate and pulled Caliburn from the stone, and became the ruler of Camelot. Throughout the next few years, Artoria would begin to bring powerful knights under her rule and eventually form the Knights of the Round Table, a group of loyal knights who act as a council to govern Camelot. Artoria would eventually lose Caliburn and be given Excalibur and its scabbard Avalon by the Lady of the Lake. Due to the powers of both Exchange and Avalon, Artoria age ceased along with all of her wounds being instantly healed, making nearly invincible. While Artoria believed she would lead Britain, she soon shut herself from her people, not connecting or sympathizing with her people. Part of this is the reason a few began to rebel against her. This would only further with her sister Morgan Le Fay. In order to produce an heir, Merlin temporarily gave Artoria "male parts," but Morgan took advantage of this and used this to create Mordred. Mordred would at first serve Artoria, but would soon rebel when Morgan told her the truth about her, but Artoria rejected Mordred, which is one of the main reasons Camelot fell. After a long battle and losing nearly all her knights in the battle, Artoria killed Mordred but received a fatal wound that would claim her life since Avalon was stolen before the battle. Unfortunately, Artoria had regrets and wondered if Britain would've been better if she hadn't become the king. Before she died, she asked her most loyal knight, Bedivere, to return Excalibur to the Lady of the Lake before she finally died to her wound.
