Cosmere Spoilers Reveal Major Plot Points
Brandon Sanderson spoiled major plot points in a recent podcast, confirming that Rock has left Roshar by the beginning of Wind and Truth and that one of Mistborn Era 3's main characters will be Koloss-blooded. Wax performed a unique feat during an explosion involving god metals Lerasium and Atium that no one else has replicated, with details to be revealed in Era 3.
- The Cosmere is a shared fictional universe where many of Sanderson's series, including *The Stormlight Archive* and *Mistborn*, take place on different planets. Characters can travel between these worlds, a practice known as worldhopping. - Rock, a Horneater, hails from the Horneater Peaks on Roshar, which houses a perpendicularity—a stable gateway between the physical and cognitive realms, making it a key location for worldhopping. His departure is tied to a novella, tentatively titled *Horneater*, that will explore his journey after he returned home to face judgment for his actions. - The Koloss were originally monstrous soldiers created through a dark magic called Hemalurgy. After the events of the first *Mistborn* era, the god Harmony altered them, allowing them to reproduce naturally. Their descendants are born as "Koloss-blooded" humans, who possess enhanced strength and can choose to become full Koloss later in life. - Mistborn Era 3 is planned as a 1980s-style story with spy-thriller elements, following the technological advancement of the world of Scadrial. - Lerasium and Atium are the "god metals" of the divine powers Preservation and Ruin, respectively. Pure Lerasium can turn a person into a powerful Mistborn, while pure Atium provides an expansive vision of the future. - The feat Wax performed involved splitting "Harmonium," the metal of the dual god Harmony (Sazed). Previous attempts to split the metal resulted in massive explosions that annihilated any Lerasium produced, leaving only trace amounts of Atium. - Wax's success in creating both Lerasium and Atium is believed to be a result of his specific *Intent* during the event, a key principle in the Cosmere's magic systems. He was trying to preserve things and stop a bomb, not just cause destruction, which allowed for the creation of both metals.
