Shadowrun takes place several decades in the future (2050 in the first edition, currently 2078). The end of the Mesoamerican Long Count ushered in the "Sixth World", with once-mythological beings (e.g. dragons) appearing and forms of magic suddenly emerging. Large numbers of humans have "Goblinized" into orks and trolls, while many human children are born as elves, dwarves, and even more exotic creatures. In North America, indigenous American tribes discovered that their traditional ceremonies allow them to command powerful spirits, and rituals associated with a new Ghost Dance movement let them take control of much of the western U.S. and Canada, where they formed a federation of Native American Nations. Seattle, Washington remains under U.S. control by treaty as a city-state enclave, and most game materials are set there and assume campaigns will use it as their setting.
