Remnant is the main setting of the RWBY series. Created by The Gods long ago, it is a future-fantasy world filled with airships, gadgets, high-tech weaponry and a form of natural energy called Dust existing side by side.
The four Kingdoms of Remnant are Vale (center), Vacuo (west), Atlas (north) and Mistral (east). Each of the Kingdoms has its own distinct culture - for example, Atlas was known for its martial nature and technological advancement, and Vacuo for its rough-and-tumble lifestyle.
Vale was located on the continent called Sanus, with Vacuo on its opposite end. Mistral is on the continent of Anima. Atlas was on the continent of Solitas. Vytal is the name of the island to the north of Vale. Other known landmasses include Menagerie, the continent to the bottom right.
The last dragon-shaped continent (to the west of Vale, north of Vacuo) remains unidentified. Although its southern region was apparently at one point inhabited, no settlements are currently known to exist on the continent.[1] The majority of the continent is geographically darkened for unknown reasons.
There are also smaller islands around the larger continents. However, it is currently unknown if any of them are inhabited or part of the Kingdoms.
With the destruction of Atlas and Vale in "The Final Word" and the "Volume 9 Bonus Ending Animatic" respectively, Mistral and Vacuo are currently the only Kingdoms left in Remnant.
