Greyhawkian History

I talked to everyone and it seems like the history of Greyhawk is a little hard to follow, which makes sense. I'm giving the initial founding of Greyhawk as the starting date even though it happened a good deal ago and will add as you uncover more about the history of the continent. I'm using tidbits about the canon lore of Faerun, but literally none of any other canon lore. This specifically affects the lore surrounding the Gods of Greyhawk besides their alignments.     I'm using years in a very clear format instead of giving specific dates since the overall history is quite long and I wanted it to be easy to read. This means that the most recent events are at the top of the timeline and the ones farthest from the present are at the bottom.
