Roy's Archon is a lantern archon assigned to be Roy's guardian and guide while in Celestia. It seems to share some of Roy's personality, including some of his dislike for clueless people (calling some of the previous spirits it guided 'clueless petitioners', which may also be a reference to the Planescape setting, where "clueless" was the standard (if insulting) term for prime material natives and petitioners was the term for the souls of the dead). Due to this, Roy and his Archon get along rather well.
