You have been bestowed a Vision, which grants you the ability to use and control one of seven elements of your choosing. A person's Vision represents their ambition, and being deprived of it can cause a person to lose their ambition. Although depending on what your ambition is, you can be unaffected from losing your Vision. A person can be flexible and use their Vision differently depending on how they apply it. You can use a Vision to create barriers, heal wounds, predict the future, fly, and even manifest sentient creatures. But the usage of Elemental energy depends on practice and skill.
Holding a Vision grants passive benefits that normal humans do not possess. You have resistance to curses and Forbidden Knowledge, even energy that is dangerous to mortals is less so for you. It's believed that having a Vision allows someone the chance to ascend into becoming a God.
