Barren will be close enough to throw a stone at, right with the weapon merchant at the red tents, literally ten feet from Lia. Simply talk to him.
Ah..Are you here by my introduction? I can see.. It is true I give information to people who come here newly, but.. These days, I'm in low spirits...somehow...Ah! I talk so much, I'm sorry.
While I pull myself together, can you hand this letter to a blacksmith named Barren Deiatt?
It is a letter I received one week ago...I've forgotten handing this to him. He seemed to waiting so much... Please tell him "I'm sorry," too.
