To review, we have already considered the first type of psychokinetic manipulation: the extrinsic manipulation of objects. While largely instinctive in use – unlike the extensive families of techniques built on top of them – reproducing these effects was relatively simple and produced the unifield vector effector, the enabling technology behind the modern tractor, pressor, and torquor beams.
The second type of psychokinesis is the intrinsic manipulation of one’s self. While more difficult to master, most people do acquire proficiency with the basic component effects of in this area, which together form the heart of psychokinetic freerunning: the rejump, in which one bends momentum in mid-air to adjust one’s trajectory and/or velocity; and the longstep, in which one uses a high-intensity pulse of mass-reduction to achieve a burst of speed, appearing to cross a room or otherwise reposition oneself in an instant.
(Body-flying is not considered part of this type, inasmuch as it is impossible to lift oneself, and it depends on extrinsic manipulation of fixed or high-mass objects.)
Work on technological reproduction of these effects led up to the development of the modern vector-control core for vehicles, from skimmers to starships.
The path of inspiration leading from rejump to core is relatively straightforward, as obvious parallels can be seen in the integration of the vector-control core with attitude control systems.
Developments from the longstep are, however, somewhat more obscured. While the work of the Precursors was readily able to support such operations on a single-person scale, it proved impossible for many centuries to build a vector-control core capable of spike operation. However, the traditional vector-control core mode is based on what is, in effect, a low-energy continuous longstep which provides lesser thrust enhancement on an ongoing basis.
This state of affairs persisted until the late 7900s, with the release of Shue Lezíär’s hypertoroid drive core. Fed by a double ring of chained flash accumulators, the hypertoroid core is capable of spiking to power levels orders of magnitude greater than standard cores for brief moments. Timed with exquisite precision to match firings of attitude-control thrusters or even main drives, a vehicle – even the largest of starships – equipped with such a core can appear to blink from one position to another in a matter of moments: a true longstep.
