Before the events of the game, Rennac is the son of an unnamed, wealthy merchant in Carcino. His supports with Colm indicate that he has siblings, and went into the thieving trade as he did not like hard work, something which his father had him do a lot when he was young. Eventually, he took a job as one of L'Arachel's bodyguards under the belief that he would be well paid because of her standing as a Princess of Rausten. However, he realized that he had made a huge mistake, as she never paid him, nor did he like her that much. Despite his numerous attempts to leave, he kept finding his way back to her.
