Arbora (Location)

Description
The great tree, the motherland that grew from the sea and supports all civilization on its branches. Some believe the great tree has its own will, and mysterious ways of exercising it.

History
A long time ago, Arbora has spread its power all around the world, corrupting everything in its path. Brave soldiers bound its power inside a barrier made if five bone pillars. These warriors were then forced to reside within the barrier to avoid "tainting" others. Those who live outside the barrier has since forgotten about the tree.
