The light of each tree is autonomous; slowly breathing, it shines brightly and then fades.

When visitors or animals approach the trees, the light changes color and a tone resonates outward. The neighboring trees will also resonate, switching to the same color and tone. This response will ripple outward to the surrounding trees; it will finally reach the trees in the mountains, and the mountains themselves will resonate.

If a wave of light comes from the other side, it signifies the presence of people there. People gain a heightened sense of awareness of the existence of other people in the same space.
