The Elim, ancient protectors of the wooded spaces, are living, animate, trees. Very powerful and yet peaceful beings, they ascended from simple plants. They can use the Aether.
The most powerful elims are monstrous. They can't walk anymore, so they seed into the earth. These Elims later became the Holy Trees. Some states that they are nearly equal to the Empyrean Lords in terms of power, but because of their peaceful nature they rarely use this strength and would never dare to oppose Aion and his servants.
