The Legion of Time series by Jack Williamson centers on time travel and the battle between competing possible futures. The Legion of Time (1938) established the concept of temporal warriors fighting to determine which timeline will become reality, a premise that has influenced many later science fiction works.
After World’s End (1938) and the other entries in the series expand on the temporal conflict. The series overlaps somewhat with the Legion of Space books, as Williamson wove his various future-history concepts together across different stories and novels.
