"It has truly been a privilege to have known you. And fought you. My name is… Connla."
Connla is the son of the Ulster champion Cú Chulainn and the warrior woman Aífe. He was raised alone by his mother.
While they were hated enemies, Cú Chulainn realised that he found Aífe appealing, so he pursued her and was beaten by Scáthach for it. They eventually parted ways, and he asked that if she bore his child to name him Connla and send him to Ulster. He was to be given three vows to follow: "To not answer his name when asked", "To not change course", and "To not back down from a fight", the worst possible rules that could be given to his son. When Cú Chulainn returned to Ireland he left Aífe pregnant. She gave birth to a son she named Connla and trained him herself.
During his journey, Connla cames upon the warrior Conall Cernach. When asked his name and lineage, he refuses to answer and is challenged to a duel where he quickly disarmed the older man. Cú Chulainn then approached Connla, asking the same question.
As he could not answer, the two fought. After duelling for an entire day, Cú Chulainn was pressed back and forced to resort to using the Gae Bolg, instantly piercing Connla's heart. Upon reaching his final breath, Connla told his father his name before passing away. Cú Chulainn then recognised the ring given to Aífe by him and that it was on Connla's hand.
Despite only being a child, he was an equal to Cú Chulainn in every way but he’s still under that Geis that makes it so he can’t tell anyone his name which means he has to aggressively imply who he is, even to his own master. Connla has a bit of an inferiority complex as he seems himself as "not his father", calling himself a "Bargin-discount Cú Chulainn" and would ask his master why he was summoned instead. He would actually get along very well with Mordred due to bonding over their "daddy issues."
He just wishes for a chance to reunite with his father and have a chance for a proper reunion.
