Guardian's Wings are rare materials in Xenoblade Chronicles. It seems to be the wing of the Satorl Guardian, and may have been intended as a drop from that boss. In the final game, they can only be obtained by overtrading with Jer'ell in Satorl Marsh after the Mechonis Core, if she has not been invited to Colony 6. According to their description, they are wings that glow when the weather is misty and the glow is just a Brocken spectre.
