"Those who become familiar with Cogsban do so through the cramped capsule of a ship hull. My trusty fairfoul, on the other hand, can bring me anywhere I want to go without the restrictions of any other aircraft. The feeling of true freedom, that's something nobody else can claim to have experienced."
--Hector, Fairfoul Tender
