Fog Weave

The Fog Weave (り) is a Third Grade Artifact.

Description
It is a piece of cloth so thin that you can see right through it. It is so light that it floats over the ground like fog and even breathing can alter its movement.

It was used by Nanachi to explain the true nature of The Curse of the Abyss to Reg, since it moves in pretty much the same way that The Force Field flows.

Trivia

 * Contrary to expectations, the Fog Weave does not repair itself.
