Timett
From A Wiki of Ice and Fire
Timett, Son of Timett is a Red Hand of the Burned Men, one of the most feared of the clans of the Mountains of the Moon. He was chosen a Red Hand, or Warleader, when he burned out his own eye as part of the initiation rites.
He chose to ride with Tyrion Lannister who was gathering an army from among the mountain clans.
