Unfortunately for Noor, his [Parry] is bottom-of-the-barrel useless, his prospects are nonexistent, and everybody he knows is telling him to throw in the towel. Faced with this harsh reality, he figures there's only one thing to do: make up for it with effort! An intense, solitary training regimen ought to do it. If one year won't cut it, he’ll train for five! If not five, ten!
