Yenfire

Yenfire is an air genasi paladin (oh wait actually is she? Why do I think this?) and Smashmouth's mutual friend and member of TACOSE.
She met the members of Smashmouth individually somewhere else, somewhere we haven't asked about, and grouped us together at a tavern in Westruun where we officially started the campaign. She was a member of the city guard and helped smuggle us in and around the city before taking us to TACOSE headquarters and initiating us as members. 
Currently, she is traveling ahead of the group with Wisp and Krego researching the Devil Lord and trying to figure out what happened to TACOSE headquarters. They were in Vasselheim researching for a while, but left for somewhere in Marquet. 
I know very little about her apparently.
