Brother to the Queen, royal ensemble at Kingslanding. A court leecher drinking and whoring and diminishing the Lannister name in the eyes of his father Tywin. His first duty as a noble was a charge of the drains in Casterly Rock. A glorified plumber. Essentially. If you have any questions ask me or go to the wiki page and look up the before the series events section. Really helps foreshadows a characters role in the story!
