Fixers are humans (and rarely Seemsians) that are employed by The Seems to fix problems that go on there. Fixers must first apply for "The best job on Earth", and wait to be accepted. If they are accepted, they must take the SAT (AKA Seemsian Aptitude Test), and pass. They then become Candidates, sometimes Briefers, and if they can prove themselves, a Fixer. There are 38 fixers on the Duty Roster, as of The Lost Train of Thought.
