Of the nine elements, force is the one that moves things directly. A shaper channels emotion through Dynus, the ninth elemental layer, and adds or strips momentum from the world with nothing in between. A thrown spear leaves the hand faster than the arm could send it. A falling crate stops a handspan above the floor. A gate four men cannot shift swings open under one finger. Where an air-shaper moves the air and lets the air move the world, a force-shaper skips the middle step.
This raises an old objection. Kethic runs on emotion, and every emotion has a flavor. Anger runs hot, grief sits heavy, fear comes in cold. Force has none of these. A force-shaper at work feels no particular way, and the push that comes out carries no color at all. So how does a magic made of feeling reach it?
The answer is that a feeling carries two things, not one. There is its flavor, the particular kind of feeling it is, and there is its thrust, the bare drive underneath it, the raw size of the wanting, which is the same whether the feeling is rage or tenderness. The other eight elements answer the flavor. Dynus answers the thrust alone, the pure want with everything it was a want for stripped away. That is why force seems emotionless. It is not the absence of feeling but its most abstracted form, will with the character burned off, and a shaper reaches it not by feeling the correct thing but by wanting, and wanting hard. Magnitude follows the size of that want. The control and attunement every Kethic element demands apply here as well (see Kethic), but what a force-shaper trains above all is the capacity to summon enormous, blank wanting and hold it steady.
They train you wrong if they train you to be angry. Anger has a shape, and the shape gets in the way. You want the wall down. Not down because you hate it, not down because you fear what is behind it. You just want it down, more than you have ever wanted anything. Then it comes down. — a sapper-instructor of the siege schools
None of this makes Dynus a magic of the mind. People hear force and picture the psy mage sliding a cup across a table by thought, but that is Psywinds work, Ezz directed by intention, and it answers to the discipline of the mind that wields it. The line between them is exact: Psywinds carry thought, and Dynus answers will. One is the idea of moving the cup; the other is the naked drive to have it move. The two are indistinguishable across a crowded room and share nothing underneath. One costs the practitioner sanity and long years of training. The other is an elemental school like fire or stone.
Force is the least theatrical of the nine and the most useful to people who build things and break them. Sappers and siege-crews channel it to throw a stone at twice the weight a counterweight could fling. A few duelists' schools train a half-second of borrowed momentum into the moment a blade lands. It throws no light and makes no sound, so a force-shaper at full effort looks like a strong person having an unusually easy day, which is the reputation the trade has always preferred.
