The Lifelands is where most of the life on Earth lives. Other names include the Twilit Realm and the Safe Zone. In this region water can exist in its liquid form, life is plentiful, and Homo Sapiens flourishes. This region moves around the globe every 1000 years, so the Eternal Migration is a fact of life. Most life follows the Lifelands westward across the globe to have just the right conditions. There are actually two lifelands, on opposite sides of the world. A point on Earth usually stays in the Lifelands for one hundred years.
