I'm here! Just waiting for a while to introduce dwarf-boy. So that there's a little departure from the norm of first posts, I thought I'd let the quest develop a tiny bit and ambush you all on the way out of town, or on the way out of The Rusty Hilt or something.
My character saw a notice in The White Horse in Rohan notifying about the quest. This might not be very realistic, though, so if there is no note in an Inn, he's probably just been lurking about behind the forge. Be patient, and don't wait. Expect me when you see me.
