The geography of the Warhammer world closely resembles that of Earth because of manipulation by an ancient spacefaring race known as the Old Ones. This mysterious and powerful race visited the Warhammer World in the distant past. Establishing an outpost, they set about manipulating the geography and biosphere of the planet. With the assistance of their Slann servants, they moved the planet's orbit closer to its sun, and arranged the continents to their liking.
