Originally, Raze had been following the Dark Faction's footsteps because he had learned that Bofan was someone like him—an individual who had come from the world of Alterian.
Not only was Bofan someone important who had left a significant imprint on the world of Pagna, but Raze also believed that he might have found a way to return to Alterian. When Raze saw the markings in the cave, he knew that Bofan wasn't just any mage but a special one.
He was the only person Raze thought might know a way back. The group Alter was another, which was why he had joined them. Rather than putting all his eggs in one basket, he had spread his chances of finding a way back.
Thanks to the Bonum Society, Raze had discovered that the item known as the Golden Globe would allow him to return to Alterian, and the last person to have the Golden Globe was Bofan.
