Meanwhile, Bernard Lowe continues the mission left to him by Dolores, spending two decades simulating near-endless realities in the Sublime, where he hopes to find a path to saving both hosts and humanity. Humans now act out the storylines set by hosts. In actuality, she is a program created by Charlotte to manage a largely docile humanity, with the hosts now controlling and managing their lives through carefully detailed and manufactured "storylines", which are transmitted directly to the minds and lives of humans through a series of radio-sonic transmission "tones" in organized metropolitan areas across the world. Two decades later, Christina, a woman resembling Dolores who works at a video game company writing non-playable character (NPC) storylines and backstories, gradually begins to question the nature of her reality after she realizes that it appears her stories are somehow translating to the lives of people in the real world. Charlotte succeeds in taking control of the world by removing world leaders and installing hosts in their place, simultaneously deploying a bioengineered virus that infects humans over the course of a generation, making them susceptible to her and other hosts' orders, effectively reversing the power dynamic between humans and hosts. Humanity has lost the war, with Charlotte Hale's host copy having filled the power vacuum left behind by Engerraund Serac and his Rehoboam, ascending as the sole power over Delos after deposing William and replacing him with an identical host loyal to her. The season is described as a "dark odyssey about the fate of sentient life on Earth." The season includes an amusement park modeled after the Roaring Twenties.
