Washakie's Rattle

Origin
Leader of the Shoshone during the 19th century, Washakie permanently altered their destiny in the face of American encroachment. During his youth, the Shoshone agreed to cooperate with their enemies the Blackfeet to stymie western travelers, while Washakie crafted his own buffalo hide rattle to spook enemy horses.

Renouncing from his warrior triumphs, Washakie instead played peacemaker with the incoming settlers. Under his command, emigrants were shown safe routes through unfamiliar territory and received back any stray cattle. They also fought with the US Army against their common enemies like the Sioux and Cheyenne, and ceded land rights to the Union Pacific Railroad. When Washakie passed away at 102, he was baptized as both a Mormon and Episcopal and received a full military funeral.

Effects
Shaking the rattle induces mental reverberations, causing the user to be repeatedly swarmed with the same thoughts from every viewpoint imaginable. Known to cause those of weak or uncompromising stature to fear for their safety and attack any they meet without hesitation. But when a more receptive person to change is immersed in their own concerns, they instead choose to accept rather than worry over the future. They will behave more leniently with strangers and be willing to overlook mistakes and cultural differences for the sake of prosperity.
