You can think of the timestream as a small tube moving through a large space of probabilities: of all the things that could have potentially happened, the path that the tube takes in this space is what actually happened. Towards the bottom are the potentialities for shadow, toward the top those for light.
Originally, throughout all of our history, our timestream has crawled through shadow and darkness. With the healing of the tear in the fabric of reality in 2010, this could begin to change. However, our long past of violence and hatred would still affect us for many generations to come.
To change the impact of humanity’s horrifying past on our future, Kirael re-plotted our timestream through this space of potentialities, creating a golden path from 10.000 years ago up to the present. The expected result is that all of modern history will change radically.
