The Line Binder is intangible, a force rather than a body. It manifests visually only at the precise moment a Perfect Line is achieved, appearing as a persistent, shimmering afterimage of the disc's ideal path. It exerts a subtle gravitational pull on the fabric of nearby dimensions, gently steering reality toward alignment. Its presence can be temporarily anchored to a physical bag tag, causing the tag to grow warm and its engraved fractal patterns to glow with the accent colors of all three Schisms.

It serves as a living bridge, its strength waxing and waning based on the frequency of Perfect Lines thrown across all three realms, thus tying the fate of the dimensions to the skill of their Linewalkers.
