Yor is a member of the Greysky City Thieves' Guild as a part of the Guild's new Fighter Outreach Program, and participated in the Ambush at Old Blind Pete's House to capture Haley Starshine. Yor yelled the name of his abilities while attacking in order to imitate the rogues. Aside from his helmet, Yor's outfit is quite similar to fellow single-class fighter Roy Greenhilt. It is also possibly worth mentioning that Yor's name is, in fact, 'Roy' spelled backward. This is quite possibly merely an in-joke by the author, as no other connection to Roy has been hinted at or even seems likely.
