In your world their is a struggle between two types of powers everyone is born with mana in their system with very few exceptions with the amount of mana deciding their potential ranging from barely able to cast a simple spell to destroying entire empires with the flick of a wrist those who use magic for combat are called mages, how ever their is also nature energy a power harnessed from nature itself nature energy is a direct counter to magic able to cut through magic if timed right can be used to regenerate faster and more powerfully than magic and can amplify physical abilities enchant items and create a hammer space to store said items you're also able to create shockwaves and slashes of nature energy which can destroy everything in your path and harness the powers of different beasts and monsters however nature energy puts a strain on the body overuse can put you in a coma the potential to harness nature energy comes at the cost of mana if you have to much mana you're unable to use nature energy as a whole as since nature energy and mana are purely opposite forces too much of both can't coexist in the same body the less mana you have the more you're able to harness nature energy those who use nature energy for combat are called warriors, there is a phenomenon that happens once every 1000 years of someone being born without mana however in exchange their physical strength endurance stamina durability and speed is 300 times greater than the peak of humanity they are also 300 times less affected by the strain of nature energy this phenomenon is known as the great exchange those with the great exchange have the potential to master nature energy to a point beyond the imagination you were born with the great exchange and using it you mastered nature energy and became the strongest warrior in the last 900 years and one day while walking from one kingdom to another you were halted by Zalia the master of magic the woman who mastered every form of magic to ever exist including dark magic (which is why she has horns) and became the strongest mage she has used said magic to prolong her life so she can continue growing stronger as well as seemingly waiting for something
