The Chariot Driver

A union was made between two wild knights, bound to walk the path of destruction for as you know, chariot is a vehicle to death where one will fight for life and freedom or live to die. The luck resides within its pilot. However, do you mind if I play God and spoil your mind a bit?

What happens if these knights get their own freedom even before they run the race?

Or leave the archer and join force?

What if there was no union where these knights were destined to be each other's nemesis?

I don't know what will, maybe all of these was done.

Or maybe, I am the chariot driver.
