In Roma I, Marcus Americanius Scriptor's family home encompassed an elongated island between the Malum and Magnus rivers on the east coast of the American continent. It was discovered during the reign of Romulus Augustus when three ships carrying salt from Africa were caught in a wind that carried them across the ocean. The island was around fifteen miles long and four miles broad. It contained a central park, several theatres, a marina, the largest atrium in the world, an underground railway, a tower that was the tallest in the world when it opened, and several renowned statues, squares, and galleries. In the bay south of the island stood the Jupiter Libertatis. 130 thousand slaves worked there maintaining the villa and tending its grounds. (PROSE: Warlords of Utopia)
