I remember there was a story about this in the original Civ RP. It began somewhere around this page: http://forum.spore.com/jforum/posts/list/1350/34469.page . I don't remember much of the details but parts included a mystery of the history not resolved even IC.

I'm gonna have to go read some of old roleplay. Memory isn't the greatest and lost a lot of notepads with random stuff I wrote down.
