That was how Orion came to assume the body and identity of Ray Wiser and had been living his life for two months.
Therefore, when he saw a girl who looked very much like Ray's sister appearing in front of him and calling him 'Big Brother,' Orion was caught off guard, with no answers to the sudden situation he found himself in.
According to him—according to Ray—Tracy Wiser had been dead for over a year at the time he assumed Ray's identity.
When he found Ray on his deathbed, he had already thoroughly checked his background and discovered that his parents had died in an accident, and fifteen months ago, his sister had also died during a dungeon raid.
Since then, Ray had been living all alone in his house, only going out when he needed rations.
