I was thinking with the Tree of Peace, that the term "bury the hatchet" is used instead of "bury the weapon" because the Mohawks, who were the founders of the League of Peace and Power, buried a hatchet. I was thinking that the description of the time prior to the League's formation, each tribe had a warchief's weapon that worked like an Ancestral weapon (ex. it was sentient with the memories of past Warchief) The weapons all inspired courage in the warriors, but it also spawned Rage, and the artifacts usually dominated the warchiefs to an extent that allowed for war to continue unending until the arrival of The Peacemaker. Each weapon can also have personal abilities unique to it.

So I need ideas for weapons to be buried under the Tree. Suggestions?
