Downy nylon - Yellow Cream

Quantity: 3 Strings

In the future, superheroes are real.
Most possess powers that are useless—spectacular at times, harmless more often than not.

But not the Machs.

When a Mach pushes past Mach 7, the world yields around them. The air stops resisting. It ignites, compresses, liquefies for a heartbeat, then detonates into incandescent turbulence. At that speed, the atmosphere itself becomes fuel.

And in their wake, something remains.

Not smoke. Not quite.

Something heavier.

Pale filaments, nearly translucent, drifting like the afterimage of an invisible blaze. Strands born of heat, pressure, and the human body under impossible strain.

Scientists call it human kinetic polymerization.

The Machs call it their shadow.

A living nylon—tempered by velocity, woven from chaos. A substance that comes into being only when a human outruns the laws of the universe, and one that no laboratory has ever managed to reproduce.
