Eden
Older maps show a continent named Elimorum, home of Eldren people [1]. However, Eden continent is more to west then Elimorum was. Eden is private-owned and has many tropical islands, tropical beaches and a lot of seas to sail. The sims in North-West have all the name 'Eden' while the other sims are named after exotic fruits.
