This life tree came into existence as a heroic spirit that continued to cater to their race even after death. Its unique ability of energy conversion and resurrection due to ancestral worship made it gain the ability to create life essence. It became capable of converting energy to the very essence of life. That heroic spirit became the ancestor of all Life trees and each Life tree that exists today represents the will of that ancestor. They are of incredible importance to the High Elves.
It is also the reason why the path of Godhood has been cut off in the home plane of the high elves. Who will dare to elevate him or herself to the same level as their ancestor and accept worship to be deified? No one. Any other answer is a blasphemy on the honor of the ancestor. All demigods are hunted before they can become gods.
