Between (Pern)

Between in Anne McCaffrey's "Dragonriders of Pern" series is a dimension through which dragons and fire lizards travel during the process of teleportation, referred to as "going between". If the dragon does not have a clear picture of its destination in mind, it is possible for the dragon and its passengers to become permanently lost in this dimension. Deliberately going "between" without a destination in mind is how dragons suicide, usually occurring when the rider that they are soul-bonded to dies of illness or injury, or if the dragon itself is mortally injured. Many characters, fire lizards, and dragons have been lost "between" (i.e. "Moreta's Ride"). In Todd McCaffrey's "Dragonsblood", several make it out of "between" after they are lost.

"Between" is universally described as a place of nothingness. Usually, for a dragon to teleport using its rider's directions, they stay in "between" for the time that it takes to cough three times. Fire lizards take eight seconds to teleport anywhere on the planet. "Between" frequently causes cystitis and child-bearing problems in female dragonriders. Going "between" without proper coordinates is a frequent cause of death for inexperienced weyrlings.

"Between" is characterized by extreme cold (far below zero yet not as cold as outer space) and induces near-total sensory deprivation in humans who travel through it on dragonback. There appears to be no breathable air "between", and riders who make exceptionally long journeys suffer the effects of oxygen deprivation. In later books, an expedition on dragonback to the Red Star wear spacesuits to alleviate this problem; dragons can hold their breath for much longer than humans without ill effects. Dragons and fire lizards deliberately go "between" to destroy any Thread which they come in contact with, as the extreme cold causes it to freeze almost instantly, whereupon it can be safely brushed off dragon or rider.

Dragons are also capable of travelling "between" times, but this can only be used when they have a point of reference for that time, such as star positions or a vivid memory. The White Dragon, Ruth, could travel between to any time without fail, including to the future. "Timing it" was known to many riders a long time ago, but, since Lessa and Ramoth brought the weyrs forward, it was kept a secret. Riders who "Time" to a very distant era without protective gear, or to a past location in close proximity of their past self can experience fatal fatigue and disorientation. Since its discovery, the knowledge of this ability has been restricted, and only Bronze dragons are permitted to utilise it under directions from the Weyrleaders. The ability was suppressed by the nature of the weyrling training in going "between", as weyrlings were deliberately given reference points which would ensure they remained in their own time. It was only when Lessa jumped "between" on her own initiative when barely trained that she rediscovered the capability.
