[Author's note: The intent for this adventure is to take reader suggestions on what the player/protagonist could do and add pages myself. The details about the protagonist can change dramatically between the different routes, but I have defined personalities in mind for the "heroine" characters.]
It was known as the burst event. It happened just over twenty years ago. Scientists were studying an artifact rumored to have the world's magic sealed inside. The scientists didn't believe that, but were very interested in the strange energy it gave off, which didn't seem to cause any of the harm ordinary radiation would, and it didn't seem that the particles were actually decaying. During a test involving electrical currents it exploded, releasing an untold number of lights that scattered into the sky, unhindered by physical barriers. After hanging in the air a few moments, they seemed to seek out and latch onto people. Those people touched by the lights generally found themselves in possession of supernatural abilities.
Chaos erupted as people began using their newfound powers. A few gifted people banded together and created a time of peace from the chaos. For a long time those who used their abilities at the expense of others were held in check. It wasn't to last forever, as years later another war broke out among the gifted.
A new age begins with you, and your recent victory. You've managed to defeat the opposition, and stand to rule over all you see. But with the war won, it's time to celebrate. You have a number of trophies in your possession. An assortment of magically gifted women opposed your rise to power, but they are now subdued and at your disposal, to use however you wish. Will you try to break their wills and make them submit? Or use them, not caring what they think. Let your minions have their way with them, pit them against each other? Perhaps you can even convince them to serve you.
Or just maybe all of the above, depending on who you're talking about. Each of them is unique in their own way, so you might find it more enjoyable to give each one personalized treatment.
