Arborea is the world of TERA Online. It is a realm created by the two titans Arun and Shara as they dreamed of what would be a peaceful realm. Arborea possessed a beautiful landscape with a variety of geographical features. Vesting from the blizzard snows of Westonia to the hot deserts of Val Aureum. However, after the veil seperating Arborea from the void around it, Agaia, was shattered, and Manahan was freed, he promptly destroyed it, leaving it as a lifeless husk that it now is.
