Pendragon is someone that is actually not that famous when the game started unlike the other members of his team. He only gained his fame when he clashed with a certain guild and that is Infernum. Despite him and Siegfried now being team members in the national team to represent their country, they actually have bad blood.
Siegfried does not want to admit it, but he will definitely lose if he goes face to face with Pendragon. The fact that Pendragon himself took care of the elite team of Infernum without the help of other players has earned him lots of respect.
The sword that is on Pendragon's back is the sword that she managed to snatch from the Infernum guild. It is a special sword that can only be bestowed to one player at a time. A sword that is safeguarded by the Lady of the Lake. A sword that is from another world called Camelot which is set on a medieval world where magic is despised and treated as the root of all evil.
