Talismans of this kind are often seen in the forests in Sumeru. They possess the ability to gather the power of grass and trees.
To prevent the erosion of the forest and, in darker times, to resist the invasion of vicious monsters, trees and vines would form impregnable shelters together.
The Lord of Verdure would grant these talismans to people, giving them unfettered access to walk amidst the forest under the guidance of streams and moonlight.
One day, the labyrinth disappeared, and the forest lost its intellect.
Even so, the people of Sumeru take these talismans as symbols of the forest's protection — and the forest answers the request of such talismans and gives its power.
