Our species - Homo sapiens sapiens, "Wisest Of The Wise - has been around for about 200,000 years. Terra Fantasia's setting is 125,000 years ago, before the most recent Ice Age.
It was a warmer world, approximately 3◦ C warmer than today (hippopotami swam in the Themes!) with sea levels approximately 5 meters higher than the present (Scandinavia was an island.)
