He was serving as a deputy ranger in the north and became interested in Vormund because of Daniel Zuse, a fugitive serial killer who was rumored to have begun traveling with the prophet under the new identity of Ethan.
In pursuit of Daniel, Rolfe traversed the north, where he eventually found the two men on the road to Hiberia. Upon confirming Daniel's identity, he arrested him and put him in rope bindings. Vormund sat beside Ethan, comforting him by speaking about faith, forgiveness, and Akhen throughout the night. Rolfe found himself listening to their conversation, and the following morning he struck up a deal: Rolfe would let Daniel go on the condition he be allowed to travel with them, watching to make sure "Ethan" did not kill again. They agreed and the three left for Hiberia.
Gradually Rolfe was converted, becoming the second official member of the Cult of Vormund. Rolfe was often at odds with the other members of the group. He was suspicious and judgmental, somewhat priggish, and aggressive when he felt he was being misled.
As the religion grew, Rolfe grew wary of their influence and feared Vormund would be in danger; his fears were soon confirmed when Vormund was arrested.
After Vormund's death and the disbanding of the cult, Rolfe came to believe that the Stirling family, which had ruled for nearly two hundred years, was cursed by Akhen. He reasoned that in order for Vormund's vision of a peaceful world to become reality, the Stirling line must be dethroned, destroyed, or both.
Rolfe founded the Eclipse, a terrorist group which sought to remove the Stirlings from power. The Eclipse's efforts culminated with the assassination of King Tristan, who was shot by arrows during a tournament.
In the ensuing chaos, Rolfe was killed by Lord Gavin Zosimus, also a member of the Cult of Vormund and an old friend of his.
