Ten Thousand Years Will Give You Such a Crick in the Neck!
I like how you're so incredibly logical and methodical about this. I think I'd just throw some species into the story and make it up as I go. Do you really do all this before you write their story?
Yes & No.
This is the first time that I've ever attempted to go bit-by-bit and actually chronicle the race construction. Most of this is usually done in my head, with just the sketches as reference points. By the time I've got the species sketch and the planet sketch a story idea will already be beginning to form, and that helps kick start some of this other stuff.
I'm already getting to the point now where I’m really going to need a story framework to give me the characters that will unveil more of the world. But I’m not quite there yet. (I'm currently working on a new novel that takes place in a setting where all this stuff is still mostly just in my head).
Today we need to construct a timeline of major world events that occurred on Och over the past ten thousand years. These will be events that will have shaped the Krikicho culture worldwide in one way or another. May not have a direct impact on the story I end up writing, but will help when developing the characters. Some of this will correspond with similar biblical events on Earth, while others will be totally unique.

Obviously this is a very vauge time-line with large gaps and such. But the local history directly related to a story best comes from the characters themselves. What this does for me is help germinate ideas for legends & myths that may play into a story as well as what kinds of things characters may come across in terms of ruins from the past or ancient artifacts. And just helps get an idea of how the culture has been shaped.
