According to my readings, the reason for the storm was an accident involving a large amount of Dark Matter and Dark Energy being trapped in one place. The results were catastrophic, resulting in the disaster. The origin point is at the north end of the Large Dark Matter Storm, and exhibits strange gravitational properties. My conclusion is that the explosion was a White Hole, which expels matter from it's center faster than the speed of light.
We have not figured out how to solve the problem just yet, but we think the artifacts on Amorgos might provide some answers to our questions.
