Isaac is a longtime resident of Portia. He enjoys books, being left alone, Cross Five, and being overly protective to his books.

Isaac can be found throughout the day in the playground with a stones board and is always up for a game of stones.


Isaac loves his philosophy. He feels that in an age where critical thinking is lacking, he is the lone rock standing against the anarchy of chaos. An avid reader of books, Isaac wants to complete his own magnum opus, "The Oral History of the Age of Darkness" before his time's up.
