In addition, the map of the Warhammer world included several locations not covered by the game, with such original names as Nippon and Cathay (Cathay is even protected by a "Great Bastion"). At the very North and South poles of the world were the Chaos Wastes, a nightmare realm from which the greatest evils of the world originated.
Other locations of note are Ulthuan, the island home of the High Elves, and "The New World", which has two continents, Naggaroth in the North, home to the Dark Elves, and southern Lustria, home to the Lizardmen. The Warhammer verse was closely based on our own, with continents laid out in a similar pattern, and the action was mostly located within "The Old World", roughly analogous to 16th century Europe. until 2019, when it was announced that the Old World would return with new rules akin to the Horus Heresy spinoff for 40K. It was officially discontinued and replaced with the Warhammer: Age of Sigmar game universe by Games Workshop in July 2015, and all official GW support for Warhammer Fantasy Battle was discontinued. "Warhammer" was a tabletop battle game that began in 1983 and was previously known as Warhammer Fantasy Battle (WHFB), its last official edition (8th edition) was published in 2010.
Warhammer was the generic name of a number of tabletop battle and roleplaying games marketed by UK firm Games Workshop. If you were looking for a character who uses a warhammer, that's Drop the Hammer (though the setting certainly isnt lacking in this).
