Kira, the main character in the story, is an orphan and has a twisted leg. In this setting (future) those with any weaknesses are left to fend for themselves and/or to die. One of the friends whom she meets is Matt. He is from Fen, which is a very poor area. He is unkempt and scruffy looking. He helps her move into Edifice. He has a dog named Branch and another friend by the name of Thomas who is also staying at Edifice. Matt gives her two gifts as the story goes on, and the second gift ends up to be her father. He was assumed to be dead after he was attacked from behind and left for dead. Matt is the reason she comes back into contact with her father and decides to help others in Edifice before joining with her father again.
