Eldertree—the biggest tree in the Mortal Online, located in the center of the twenty-fifth floor.
It was so big and tall that it went over the cloud layer, and rumors say that its peak might even reach the outer space. There were many mysteries surrounding its origin and purpose.
Its enormous roots protrude out of the ground and seem to stretch on endlessly. Those roots were wrapped around the entire floor, and between the roots were thick forests that still hadn't been fully mapped out.
That wasn't all.
Somehow, it was unclear who built it, but inside the Eldertree, there were stairs, living places, and hidden passageways that led to unknown parts of the tree.
Some experts said that it must've taken someone thousands of years to build all of that.
The institute was created inside the Eldertree, thus receiving the name Eldertree Institute.
There, mercenaries from all corners of the world gathered to train.
