Chalatee

Chalatee is a hot and humid desert/feudal world, that is also the Adeptus Astartes home world of the Dust Knights Space Marine Chapter.

Background
The Chapter's Homeworld is the Desert-Feudal World Chalatee. The people are either scattered into different medieval kingdoms or tribes, many of whom are nomadic, trying to survive against the great heat of the planet's sun, or living near the cool mountains and caves. There are a small number of oasis with plenty of water or plots of land that can be farmed. Most of these areas were artificially made by the Dust Knights, providing the natives the limited amount of necessities so they can birth future recruits.

From time to time, the planet will have cases of severe weather, followed by sandstorms. In rare times, there will be heavy rain, lightning and tornado too. The people of Chalatee see this as both a blessing and a curse, as the storms will provide water for their artificial water collectors, but also because of how violent the storms can be sometimes. The severeness of the weather is what made the Dust Knights so skilled in aerial tactics.

The Scorpion
The Fortress-Monastery known as the Scorpion, it is where the Dust Knights resisde when not in battle. The Scorpion is in fact a massive mobile fortress, nearly around the same size as a Hive City. Its large wheels enable it to trek across the desert and mountains of Chalatee with no trouble. Armed with weaponries to repel both air and ground forces, very few can hope to breach this moving fortress. Its mobility is so the Dust Knights can locate the tribes scattered across Chalatee when seeking out new recruits and ensure that there are no invaders on their world. The Chapter's fleet is stationed at an orbital station around the planet, allowing the Dust Knights to mobilize quickly for campaigns, or for damaged ships to have a place to dock and be repaired. Only the Chapter Command is stationed aboard the Scorpion, along with important relics, the bodies of fallen brothers, the main armoury and so forth.
