You have become a Divine Spirit, a being of Divine mystery that embodies natural phenomena or abstract concepts that serve as the foundation of the world itself. As a god you have enough power to battle and easily win against dozens of heroic spirits at once, and have the potential to grow to rival chief gods of entire pantheons, such as Zeus, Amaterasu, and God Arjuna, beings so powerful that they are unbound by the time axis.
You possess a Divine Core, a source of true ether that rivals that of a Holy Grail in terms of energy production and output. You are incredibly hard to kill and capable of regenerating even from the complete destruction of your soul whenever you wish to do so. The only way for you to be able to die is to be completely forgotten about, and even then, you would still need to be killed to put you down for good.
Your most potent ability as a divine spirit however is the ability to wield Authority, which is the divine right of gods, given to them by the planet itself, to shape and alter the world based on what phenomena or concepts they embody. These are tremendously powerful and esoteric capabilities; they allow for miraculous feats such as creating a world, event shifting and inducement, time-flow manipulation, and kingdom-building, and much more. While normal Skills and abilities "achieve a certain result based on some logical process or principle," Authorities "realize a result simply because the user has the right to do so."
You can freely use your Authority without inducing strain or having damage inflicted upon you, just as it was during the Age of Gods.
