From the Introduction: Welcome to the world of Phydea, a large planet housing many civilizations, fantastic creatures, and endless adventure. This world is made up of two main continents, Macea and Archaea, both separated by a vast sea dotted with thousands of islands. The cultures found here use ancient technologies that generally conform to the Late Bronze Age on Earth. In fact, this world is a kind of alternate-Earth, where many things are similar to our own world; much of the plant and animal life, minerals, climate, technology and peoples are very similar to those found on Earth in the Late Bronze Age.
