Pure Aura Manipulation

After you die, you are reborn on a planet very similar to earth. The key difference is that In this world, humans have developed a Pure Life Essence. As such, humanity has been purified of negative traits such as greed and the like. Additionally, humans have gained an ability called Oneness With Nature, in which they can manipulate all aspects of nature around them, purify/heal wounds, and even create new life.

This pure civilization is at war with "The corrupted ones", humans who have refused to let go of their previous life, or previous vices. These individuals have a Corrupt Life Essence, and have gained an ability known as Corruption of all, in which they can destroy nature and corrupt humans
