Theros is a set of three expansions to the Magic: The Gathering game, consisting of the sets Theros (September 27, 2013), Born of the Gods (February 7, 2014) and Journey into Nyx (May 2, 2014). The setting was later used for a Dungeons & Dragons sourcebook, Mythic Odysseys of Theros (2020). The lore and aesthetics of the game setting was based on Greek mythology.
