Most Warhammer 40,000 fiction is set around the turn of the 41st millennium (about 38,000 years in the future). Although Warhammer 40,000 is mostly a science-fiction setting, it adapts a number of tropes from fantasy fiction, such as magic, daemons, and races such as Orks (Orcs) and Eldar (Elves); "psykers" fill the role of wizards in the setting.
