On Pandora: Woodsprites
The Na'vi, Pandora's blue inhabitants, consider these glowing, floating seeds sacred. They come from the giant, willow-like Tree of Souls, which connects to all living things on Pandora and directly to the Na'vi deity, Eywa. The seeds are not just blowing in the breeze — they're traveling with spiritual purpose.
