The story “Two Worlds” (“Due Mondi”) by Francesco Verso was published for the first time in 2011. It was translated into English by Sally McCorry.

After a global climate catastrophe, genetic engineering led humanity to split into two different species: the Aquamancers, who live in the seas, and the Aeromancers, who live in the mountains. When an Aeromancer gets rescued by a group of Aquamancers while searching the Tower of Seeds, a collaboration between the two human species can save the world’s plants.
