The Stoics heavily outnumbered the Reformists and believed that Forerunner technology should be revered. The Reformists contrarily believed that Forerunner technology should be studied and integrated into their own culture and society. Ultimately, the theological battle between the two groups culminated in a large group of Reformists boarding the Forerunner Keyship and leaving Janjur Qom.
