The Maestro Prodigy Achird

One dimension, two dimensions, three dimensions, seven. You are a child genius who theorized how to access the seventh dimension. In your spare time you compose piano music in the hyperpop genre. Even though you're smart, you're still a kid and enjoy movies about space pirates and judo. You do part time work for The Undead Rites because they offered you a near unlimited supply of white chicken chili.
