When she was young, Caesar sees a piano as a piece of junk while her dad tells her it's junk that was reclaimed by humanity from the Hollows and that it is a land that belongs to hope in a place of nothing. She did not understand for a time until the day she met Lucy, a girl from New Eridu who left for the Outer Rings in search of something she could not get in the city. Caesar offered to take her back at first until she started playing the piano which stunned Caesar. Caesar began interacting with Lucy who thinks the Outer Rings isn't too bad of a place as it still has music that can be played and a melody that can be formed. Caesar began learning to play the piano from Lucy and slowly understood what her father meant about a land of hope in a place of nothing.
