The Task of Chaos

Fate and Chaos are two entities whose followers fight each other, but only a small portion of them understand why they do so, or rather only they know the true reasons.

Most of Fate's followers fight because they believe that Fate is the true good, even among the Fate Knights only a small fraction of them know what Zayne saw and what he heard now.

Why Order, Oracles, and Crusaders fight on Fate's side is understandable. 

It's not that they want power, although they do, and it's not that they don't know why, no, they just realize it's for the best. After all, first and foremost, Fate is about stability.

Fate was both fair and completely hypocritical as it would never help anyone who really needed it. While someone talented or lucky could easily get Fate's attention and become a Fate Knight.
