or Na'vi Name: Vitraya Ramunong is a giant willow-like tree that is said to be the closest connection to Eywa on all of Pandora.
The Tree of Souls, besides being a very close connection to Eywa, also works as a way for Eywa to directly interact with the world through the seeds of the tree. The tree has the capability to connect directly to the nervous system of all living things, and is not limited to the queue that Pandoran wildlife possesses.
