The term "Dûnyain" refers to a fictional group from the series of novels written by R. Scott Bakker, particularly in the Second Apocalypse series. The Dûnyain are a sect of philosophers and warriors who focus on the mastery of self and the manipulation of others through understanding their motivations and desires. Central to the Dûnyain philosophy is the concept of "the Outside," which represents the world beyond one's own perception. They believe that true power comes from transcending emotional attachments and mastering one's own will, allowing them to navigate the complexities of human interactions effectively.
