From Gondor, was sent to the Comb and Wattle Inn, Combe in Bree-Land, to check out rumors of Angmar presence.  While visiting Archet, was caught in the "hobbit fiasco". Galadriel's dream revealed he needed to help the locals, but didn't know how. After meeting Gladnagl, it became clear he must help her in uniting the Free People of Middle Earth in common cause to combat the emerging evil.  As a minstrel, his role is to motivate and encourage the factions to work together towards this common cause.

"Mithlind" is Sindarin for Grey Singer. It's not clear why his parents named him this, although it had to do with a vision they received in a dream shortly before he was born.
