No incident, however seemingly trivial, is unimportant in the scheme of things. One event leads to another, which triggers something else and before you know where you are, the ramifications spread far and wide throughout history, echoing down the ages; getting fainter and fainter but never completely dying away. They talk of the harmony of the spheres, but history is a symphony of echoes, every little action has huge consequences. They're not always apparent and sometimes, in our game, sometimes effect comes before cause, not after. It makes your head ache.
