Galactic 4th Edition
At one point in time, every race has dabbled with arcane energy, using the magic to improve life or to destroy it. Races that left the magic behind in their world’s history vary in their reasons. For Humans, they started to focus their energy on technology, a method that was faster, easier, and cheaper than magic, at least at the time.
The original fey-like residents of the Sylvin System called this magical arcane energy Chaotics, as their descendants still do. It pulls at the strings of reality, and is reshaped to the manipulator’s design. It takes great force of will or personality to manipulate the fabric of reality, and few find themselves with the ability to do so.
The Sylvin method of combining Chaotics with technology is unique to their society. Other societies that use Chaotics for star travel usually have organic based technology.
