Crafted from lightweight yet durable parchment, the scroll's surface shimmers with a subtle iridescent sheen, as if infused with the very essence of the shifting winds. Mystical runes etched along its edges grant the bearer the ability to sense and subtly influence air currents, aiding in both flight and the precise control of hurled discs.

The Zephyr Theorem does not exert agency itself, but rather acts as a repository of knowledge and a conduit for mystical forces, guiding its bearers in mastering the ever-changing winds and honing their aerial prowess.
