The Invisible Prince is first seen in Episode 3: Safety in Numbers, when he and Martin Bohm commence chase after a woman is hit by a car and the prince "steals" a book from her handbag. It turns out the book is actually his and that it contains numbers, much like the book that Jake owns.
He has a brother who lives in an apartment block that is nearby to where he can usually be found.
He makes a return in Gyre: Part 2, when he helps Jake to get onto the subway by distracting a pair of police officers.
He is homeless.
"Once Upon a time there was an Invisible Prince who served a Silent King, and together they helped people who never knew they were there."
