Orpheus is from Earth and is a strong admirer of Inkheart.
He can also read characters in (unlike Mo) and out of stories.
In Inkspell Edit
Orpheus is read into Inkheart near the end of the book by Meggie, so he can write something to bring Dustfinger back because at that point Dustfinger is dead.
Orpheus brags about how he read himself into the book.
He makes Farid his servant by tricking him into thinking he could bring Dustfinger back faster if he had a servant.
In Inkdeath Edit
Orpheus reads himself treasures to pay for the maids, chefs, and a bodyguard he hired.
