Applied Semantics
Applied semantics is the system of narrative manipulation, often perceived by the unaware as ‘magic’, that seam-walkers use to influence and traverse the multiverse.
The basic principle of applied semantics is that instead of directly manipulating matter, which requires energy far in excess of what even the most powerful seamships can muster, the seam-walker manipulates the meaning inherent to matter and the multiverse, abhorring a contradiction, adjusts physical reality to match.
The meaning of a brick wall, for example, is focused on hardness, impenetrability, solidity; a seam-walker who wishes to pass through a brick wall to the other side may therefore change its meaning to reflect softness, permeability, ephemerality. With this semantic contradiction in place, the force of the local narrative will make the wall match its new meaning, and the seam-walker will be able to walk through it with ease.
