Estrangement begins as a water-dwelling creature, and learns to swim through the air using psychokinetic powers as its body evolves. Adult Estrangements like to travel far and wide, but as a result, their children spawn alone in foreign places, away from any guidance or sense of who they are. Some young Estrangements tend to find their first homes among populations of Lonely, where they manage to fit in due to their similar body shapes and mutual love of water.
