The Way of Kings

Conservation of force is maintained; for instance, if one is attached to a heavy stone, you will need the same strength to lift the conjoined fabrial that you would need to lift the stone itself. There appears to be some sort of process used during the creation of the fabrial that influences how far apart the two halves can go and still produce an effect.

Reversers: Using an amethyst instead of a ruby also creates conjoined halves of a gemstone, but these two work in creating opposite reactions. Raise one, and the other will be pressed downward, for instance.

These fabrials have only just been discovered, and already the possibilities for exploitation are being conjectured. There appear to be some unexpected limitations to this form of fabrial, though I have not been able to discover what they are.

Warning Fabrials

There is only one type of fabrial in this set, informally known as the Alerter. An Alerter can warn one of a nearby object, feeling, sensation, or phenomenon. These fabrials use a heliodor stone as their focus. I do not know whether this is the only type of gemstone that will work, or if there is another reason heliodor is used.

In the case of this kind of fabrial, the amount of Stormlight you can infuse into it affects its range. Hence the size of gemstone used is very important.

Windrunning and Lashings

Reports of the Assassin in White’s odd abilities have led me to some sources of information that, I believe, are generally unknown. The Windrunners were an order of the Knights Radiant, and they made use of two primary types of Surgebinding. The effects of these Surgebindings were known – colloquially among the members of the order – as the Three Lashings.

Basic Lashing: Gravitational Change

This type of Lashing was one of the most commonly used Lashings among the order, though it was not the easiest to use. (That distinction belongs to the Full Lashing below.) A Basic Lashing involved revoking a being’s or object’s spiritual gravitational bond to the planet below, instead temporarily linking that being or object to a different object or direction.

Effectively, this creates a change in gravitational pull, twisting the energies of the planet itself. A Basic Lashing allowed a Windrunner to run up walls, to send objects or people flying off into the air, or to create similar effects. Advanced uses of this type of Lashing would allow a Windrunner to make himself or herself lighter by binding part of his or her mass upward. (Mathematically, binding a quarter of one’s mass upward would halve a person’s effective weight. Binding half of one’s mass upward would create weightlessness.)

Multiple Basic Lashings could also pull an object or a person’s body downward at double, triple, or other multiples of its weight.

Full Lashing: Binding Objects Together

A Full Lashing might seem very similar to a Basic Lashing, but they worked on very different principles. While one had to do with gravitation, the other had to do with the force (or Surge, as the Radiants called them) of adhesion – binding objects together as if they were one. I believe this Surge may have had something to do with atmospheric pressure.

To create a Full Lashing, a Windrunner would infuse an object with Stormlight, then press another object to it. The two objects would become bound together with an extremely powerful bond, nearly impossible to break. In fact, most materials would themselves break before the bond holding them together would.

Reverse Lashing: Giving an Object a Gravitational

Pull

I believe this may actually be a specialized version of the Basic Lashing. This type of Lashing required the least amount of Stormlight of any of the three Lashings. The Windrunner would infuse something, give a mental command, and create a pull to the object that yanked other objects toward it.

At its heart, this Lashing created a bubble around the object that imitated its spiritual link to the ground beneath it. As such, it was much harder for the Lashing to affect objects touching the ground, where their link to the planet was strongest. Objects falling or in flight were the easiest to influence. Other objects could be affected, but the Stormlight and skill required were much more substantial.
