- For Liam O'Brien's non-canon NPC, see Spireling Shenn (non-canon).
Spireling Shenn is a six-foot-tall human with long blond hair that trails past the middle of his back. He has fine features, although his face is a bit weathered from age. He wears a dark gray cloak and has a red-tinted monocle that he wears over one eye.
"Dangerous Dealings" (1x42)
After Emon was devastated by the Chroma Conclave, Vox Machina ventured into the Clasp's territory to seek an alliance. They hoped to ensure the safety and survival of Emon's remaining citizens while also developing an information network with the Clasp's spies.
Spireling Shenn came forward to negotiate the deal. In return for the Clasp's aid to Vox Machina, Shenn asked for an introduction to certain key power figures in Vasselheim so he could establish his crime network there. Percy seemed ready to take the deal, but Vax'ildan—himself a member of the Clasp—refused to shake hands. Shenn then made clear that Vox Machina would not be welcome among the Clasp in the future.
"The Frigid Doom" (1x64)
Assum Emring mentioned to Vox Machina and their war council in Whitestone that Tofor Brotoras, who had remained in Emon, was working with Shenn to get survivors underground. However, this information may have been unreliable as it actually came from Raishan in disguise as Seeker Assum.
- While DMing a one-shot special episode, "Critical Role Extra – The Return of Liam!" (Sx15), Liam O'Brien played a version of Spireling Shenn as an NPC.
