What “cosmere” means

Wikipedia

The Cosmere is a fictional shared universe created by Brandon Sanderson, serving as the setting for many of his fantasy novels and related works. It includes series such as Mistborn, The Stormlight Archive, Elantris, and Warbreaker, along with novellas, short fiction, and graphic works. Individual series are set on different fictional worlds but are linked through shared cosmological elements and narrative connections.
