The Intention Craft is an aircraft designed by Lord Asriel in the war against the Authority. The device is powered by the intention of the controller and their daemon using hand holds. The Intention Craft is a "flying" machine, but has no engine or wings (some fans have speculated that it uses anti-gravity). It has a cockpit and controls like a gyropter (helicopter from one of Pullman's fantasy worlds) and six bug-like legs. However, there is a helmet and leather wrapped mechanism on a string, so that the craft can be controlled by the driver's intentions. It can only be used by a being with a dæmon, as the Daemon bites on the mechanism attached to the string. At least two exist, one more advanced than the other.
