On the lost world of Exegol, Sith cultists gather to venerate the ancient Sith Order and swear fealty to the current Sith Lord. Darth Sidious has built this following into a military weapon during the years of his exile, with a generation of children raised as workers and soldiers in secret shipyards, factories and military camps. By combining these forces with those of the First Order, Sidious will ensure eternal Sith rule.
