RWBY: World of Remnant Season 3 Episode 4 - Vacuo Episode Title:Vacuo.Episode Description:Qrow remarks Vacuo may be worse off than Mantle was. Located at the western end of Sanus, it was once "a paradise"- an oasis in the surrounding desert bursting with natural resources, geographical defenses and the world's largest Dust deposits. Many nomads settled a thriving lifestyle, but their society became complacent while the rest of the world had to adapt to survive. Soon, the other kingdoms set their eyes on Vacuo's resources, sparking what would be the "Great War". After years of conflict, unrestricted mining and ecological disasters, Vauco was reduced to a barren wasteland: citizens live in makeshift homes, traveling frequently in response to fleeting resources or occasional Grimm attacks. While still a kingdom, its formal government goes unheeded by citizens with Shade Academy considered the only source of order. However, its citizens still have a mutual respect for one another, following an unspoken rule: "If you can survive here, then you're welcome here." Qrow recalls how Ozpin said the four kingdoms represented what mankind is capable of when working together, lamenting that they would need Ozpin now to do so.
