 The means of traveling through timelines is a flying saucer-shaped "conveyor" using the Ghaldron-Hesthor field generator, which was developed via a fortuitous fusion of attempts to develop faster than light space travel with ones attempting to explain certain psychic phenomena.Conveyors are fixed in place, which means that as they travel through timelines, they may end up inside nuclear reactors or other hazards or be caught in warfare (a common activity on at least one timeline in nearly every trip, Paratimers note).Weakening of the transposition field is a concern of Paratimers.
