This banner is a rectangular military standard depicting a white, two-tailed swirl—like a stylized overhead view of a hurricane—on a dark green background. The banner’s fluttering movements seem slower than they should be.

An unfurled banner of the storm’s eye always waves more slowly than nearby flags, and it seems unaffected by the wind or by the movement of its bearer.
As long as it is held aloft, the banner automatically suppresses (but does not dispel) fear effects on all creatures within 20 feet. It also prevents any creature within 20 feet from becoming confused or stunned.
Alternatively, you can mount the banner on a backpack frame to leave your hands free. The backpack frame costs 5 gp and weighs 10 pounds. While so mounted, the banner occupies your shoulders body slot.

Lore: The swirling pattern on this banner was common to elite military units in the last great war (Knowledge [history] DC 15).
Such banners provided protection from psychological tricks employed by creatures such as mind flayers (Knowledge [history] DC 25).
