This region is the first level of the planet, which contains a number of tiers like a wedding cake, separated by vast mountain ranges.

Okeanos consists of a beach, an ocean, and a small forest and is populated by nymph like humans who originated in and near ancient Greece.

In this new world, Wolff regains his youth and vigor and falls in love with a local woman named Chryseis who lived in Troy at the time of the Trojan War.

When Chryseis is kidnapped, Wolff follows after her, climbing to the next level of the world, Amerind, a plains region populated by Native Americans and centaurs.

At the end, Wolff/Jadawin is reunited with Chryseis and restored to his rightful place as ruler of the World of Tiers, his experiences as a human on Earth having tempered his previous cruelty.
