The Prince of Erebor

King Thror sees Dis' newborn as a curse to the line or Durin and orders his death, however Thorin won't allow it and escapes with Kili. He brings the babe to the West where he is found by a Hobbit lass and raised as one of their own until the day where Thorin returns to him and wishes to bring him home. But Kili isn't particularly keen on it and neither is his brother Bilbo.
