The Godson Prodigy Alder

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 hill country blues genre. Even though you're smart, you're still a kid and enjoy movies about pufferfish and rugby league. You do part time work for The Alliance of Dark Matter because they offered you a near unlimited supply of vodka.
