Homo Sapiens, or Humanity, is the dominant life form on Earth. Like most other life, Homo Sapiens is subject to the Eternal Migration. Despite this, humans built cities which flourished until the Hotlands came over them. These cities would be rediscovered one thousand years later, when the Lifelands came back into that area. Humanity actually lived in both the Lifelands, on opposite sides of the globe. The currently accepted theory for this is that the south pole was once much warmer, allowing people to travel across it.
