Alright so at some point I picked up the acknowledged adventurers seal not knowing what it was. I used 60 CP to get it and just found out yesterday that it was using up my CP. So I went to Heidel to give it back to Jordine and he wasn't there. I went to Glish to see if he was still standing on that rail and he wasn't there. Does anyone know where he is?? I have completed the Calpheon quest line but not the Mediah. Please save my 60 CP!!

He's probably gone into hiding if you finished Calphaleon quests but you can return it to Igor Batali too I believe. Should be just like renting a flute or matchlock 

I believe the other guy in Jordine's chambers becomes the new lord after doing the Calpheon questline and can be returned to him If you got the seal from Jordine before. Edit: Crucio Domongatt is the name of the guy you need to find.

Hope this helps. Will edit his name in once I find out his name.
