Explorer of the Great Tree

There is one tree ath the center of the woods that towers over all others around it. This great tree pierces the clouds with ease and is visible from any tree top in the woods. This mighty tree is said to be way over 20 000 ft tall and about 5200 ft in diameter. But this is not the only secret the tree holds. The inside of the tree has been altered to house the city of Engis Anur. This grand city takes up a small portion of the tree and is devided on over a hundred floors. It is located in the first few thousand feet. Little is known of what lives in the upper parts of the tree. Could there be anything at the top?
