Each Bastion City had thousands of arrays that helped divert the energy spreading from the roots, trunk, branches, and many other parts of the Ethereal Lumina Tree. The density of arrays at the roots was the lowest, but it was important, since that was where the root absorbed energy from the Dragon Realm Vein and distributed it across various Dragon Veins throughout the realm to grow and breathe heaven and energy.
It was said that this was one way in which Dragon Veins came into existence karmically.
Dragon Veins were the earthly source of heaven and energy in a land that isn't near the Ethereal Lumina Tree and the Realm Core. In the Upper Realm Space, it was usually tiered into Heaven Dragon Vein that supports Exalts, Earth Dragon Vein that supports Empyreans, and Mortal Dragon Vein that supports Immortal Emperors and below.
