[@Vec] If you mean when Ull went to sleep on Cygnea and woke up to find a fully formed biosphere there, probably several hundred years ago. It was before the foundation of Alefpria, before the Urtelem were given language, before the first Ogres, and before Gerrik discovered fire (other places had it though). The timelines might not be very consistent but I think we can safely say that it was a [i]very[/i] long time ago.
