I have heard tell that you are looking to make your mark and presence known...admirable. I think that I may be able to assist you with this, but it will take some work.
You received a letter from your trainer in Bree-town asking for you to return to him. Apparently, there is something that he wishes to teach you.
Burt Ninetails sent you a letter requesting that you visit him at the Prancing Pony in Bree.
Deliver the letter to Burt Ninetails at the Prancing Pony in Bree.
