While the idea of Xenk in Honour Among Thieves being a DMPC or an NPC is funny, I’m much more a fan of the idea that he’s actually a PC controlled by somebody else who played a full campaign with the same DM. Because meta textually, I can clearly imagine the conversation between the DM and Xenk’s player:
DM: “…So yeah I kinda fucked up the CR’s of the Underdark encounters but my current group is super excited and determined to head down there and since Xenk was already down there before…dude please help me, one session.”
Xenk’s Player: “I dunno, Xenk’s character arc felt pretty complete to me…”
DM: “Wait…The Red Wizards are the bad guys of this campaign too! You can finally settle the score with that asshole Dralas!”
Xenk’s Player: “…You sonnuvabitch, I’m in.”
DM: “YES! Oh also, Edgin’s-the Bard’s-backstory has him being a former Harper, so I have some ideas on how you could drive him nuts…”
