From Lives of the First Companions, by Randolph (777):

Lifthrasir is perhaps the most mysterious of the First Companions: a wanderer and mystic by nature, he would venture far from New Jerusalem on his own, recording his thoughts as he explored harsh and distant lands. These recordings garnered him a group of devoted followers to whom he tried to impart his wisdom5358

In the troubled time following the Founder's disappearance, Lifthrasir and his disciples set out on a journey to reach the opposite end of the world by foot. They have not been heard from since.
