Estin, The Celestial City
The world trees are a series of grand trees scattered around the continent. Each tree is nearly 400 feet tall and 100 feet across. Of the original 6 only 4 still remain. Much like Quehara the other world trees have elven groves around them although none are so expansive as Quehara. The only exception is the world tree in the human city of Kenta. However, that particular world tree has been fading over the past century.
The two world trees that are gone were lost in a vicious war started by the elves. The war was so long ago that there are few elves still living who know the initial cause. All that is left of the world trees are charred masses of dead wood. Some researchers have noted though that there is still magic lying dormant deep within the trees, but none have managed to find or utilize the power.
