Pearl and Elio return to Atlamaria after their encounter with The Heretic God, Khaeros, hoping they will return to their normal lives. Instead, they find that The Triarch was not stopped - let alone slowed down - by their efforts. They have already begun their push for total control, leaving Atlamaria on the brink of tyranny. Burdened with grief and the weight of their new challenge, the pair must navigate their messy relationship while keeping sight of their goal to stop The Triarch. As the clock ticks down for Atlamaria, the line between hero and monster becomes incredibly thin as the pair faces just how far they're willing to go for the greater good.
