When Desther and his Helmites were revealed to be traitors, Fenthick was shocked. He journeyed to Helm's Hold after Desther to confront him, but many viewed this as confirmation that he had been working with Desther. The Hero of Neverwinter found Fenthick, frightened and confused, in a stairwell of Helm's Hold. Fenthick returned to Neverwinter, where he was executed for crimes against the city.
Some time later, his spirit appeared in the Tomb of the Betrayers, where it was defeated by a group of adventurers.
- "Fenthick looks concerned for those suffering, obviously willing to do anything if it would help the situation. His face looks weary, but hopeful." (Prologue, NWN)
