He was serving as a deputy ranger in the north and became interested in Vor because of Warren Zuse, a fugitive serial killer who was rumored to have begun traveling with the prophet under the new identity of Daniel.
In pursuit of Daniel, Rolfe went to Io, where he found the two men about to leave. Upon confirming Daniel's identity, he arrested him and took him to the local jail. Vor followed them and sat outside Daniel's cell, 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 Daniel did not kill again. They agreed and the three left for Zemar.
Gradually Rolfe was converted, becoming the second official member of the Cult of Vor. He would often claim, however, that he was the first to follow Vor because Daniel, having later committed another crime, could not have been true in his conversion.
Rolfe was often at odds with the other members of the group. He was suspicious and judgmental of Daniel, Sofia, Athanasi, and Kemet in particular, accusing them of weak or insincere faith. His distrust and paranoia was usually tempered by Vor.
As the religion grew, Rolfe grew wary of their influence and feared Vor would be in danger; his fears were soon confirmed when Vor was arrested and beheaded by King Tristan.
After Vor's execution and the disbanding of the cult, Rolfe came to believe that the Stirling family, which had ruled Wallachia for nearly two hundred years, was cursed by Akhen. He reasoned that in order for Vor's vision of a peaceful world to become reality, the Stirling line must be dethroned, destroyed, or both.
Rolfe founded the Insurrection, a terrorist group which sought to remove the Stirlings from power. He also added "Drusus" to his name, for unknown reasons. The Insurrection'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 Vor.
