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.
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.
A second form of Surgebinding involves the manipulation of light and sound in illusory tactics common throughout the cosmere. Unlike the variations present on Sel, however, this method has a powerful Spiritual element, requiring not just a full mental picture of the intended creation, but some level of connection to it as well. The illusion is based not simply upon what the Lightweaver imagines, but upon what they desire to create.
In many ways, this is the most similar ability to the original Yolish variant, which excites me. I wish to delve more into this ability, with the hope to gain a full understanding of how it relates to Cognitive and Spiritual attributes.
