When a daemon was about to attack him with his back turned, Celica pushed him away and received the blow that forced her into the depths of the shrine as the mouth of a mysterious entity devoured her.

The brigands' malevolence resulted in them becoming daemons and attacking the village, while chasing Celica Crowe into the shrine in Tranquil Woods. Arthur rushed after her, slaying the daemons until he made his way to her. However, during a Scarlet Night that would become known as the Opening, brigands attacked Aball for reasons unknown. He also inspired both Laphicet and Velvet to become exorcists. While living in the village, he helped Celica's sister, Velvet make ends meet, while continuously taking care of Celica while she was pregnant. Over time, he and Celica fell in love and married. Celica introduced herself and asked him to join her for dinner. Claiming that he had failed his master after a ten-year journey, Arthur stated that he did not deserve to live, but Celica told him that life was not something one had to earn and that such feelings were proof that he was alive. At least ten years prior to the story, Artorius, who went by the name Arthur at the time, was found in the forest outside Aball by a woman named Celica Crowe, who listened to his troubles before encouraging him to rest and eat, offering him an apple.
