There is a 90s computer game with writing far better than most books. Part of it attempts to answer a simple question, “what can change the nature of a man?” Man as in a human of either genders. If you have a high enough wisdom statistic, you can open an item. A bronze sphere, here is a sample of what the muses whispered to the writer…
“ The sphere wrinkles in your hands, the skin of the sphere peeling away into tears and turning into a rain of bronze that encircles you. Each droplet, each fragment that enters you, you feel a new memory stirring, a lost love, a forgotten pain, an ache of loss - and with it, comes the great pressure of regret, regret of careless actions, the regret of suffering, regret of war, regret of death, and you feel your mind begin buckling from the pressure - so MUCH, all at once, so much damage done to others… so much so an entire FORTRESS may be built from such pain. And suddenly, through the torrent of regrets, you feel the first incarnation again. His hand, invisible and weightless, is upon your shoulder, steadying you. He doesn’t speak, but with his touch, you suddenly remember your name…and it is such a simple thing, not at all what you thought it might be, and you feel yourself suddenly comforted. In knowing your name, your true name, you know that you have gained back perhaps the most important part of yourself. In knowing your name, you know yourself, and you know, now, there is very little you cannot do."
Nameless One: What can change the nature of a man?
The Transcendent One: I have seen you live a countless lives, Broken One, I have lived your endless quests that accomplish nothing except spread your torment through the multiverse. Then, this is my answer and you are my proof: Nothing can change the nature of a man.
Nameless One: You are wrong. If there is anything I have learned in my travels across the Planes, it is that many things may change the nature of a man. Whether regret, or love, or revenge or fear - whatever you believe can change the nature of a man, can. I’ve seen belief move cities, make men stave off death, and turn an evil hag’s heart half-circle. This entire Fortress has been constructed from belief. Belief damned a woman, whose heart clung to the hope that another loved her when he did not. Once, it made a man seek immortality and achieve it. And it has made a posturing spirit think it is something more than a part of me.
The Transcendent One: Believe what you will. You will die again, and you will forget again.
