Shortly after becoming the new apprentice of Darth Plagueis, Darth Sidious accompanied his master to his frozen homeworld of Meghito, where Plagueis subjected him to Meghito's intense cold atop a mountain. Unaffected by the planet's freezing temperature, Plagueis informed his apprentice that his intent was for the frigid temperatures in the dark side to kill Palpatine, so that he'd be reborn as Sith Lord. As Sidious froze, Plagueis forced him to repeatedly recount the slaughter of his family in detail, with the goal of extinguishing any lingering feelings of personal connection to his family, and eliminating all sense of regret or compassion. Additionally, as their time on Meghito continued, Plagueis waited to top the mountain, hoping that Sidious's hatred would drive him to want to murder his master. During this time, Sidious was deprived of food, water, and sleep. While he was forced to climb to reach his master, but repeatedly failed. When Sidious finally succeeded in reaching Plagueis, he learned his master used a mind-clouding technique on him, discovering Plagueis had been a force created doppelganger. Soon thereafter, Plagueis informed his apprentice that it would take him not a standard day sooner than a decade for Sidious to become a truly powerful Sith Lord.
