Roostock

Roostock is a fictional city featured in the *Warhammer 40,000* tabletop wargame and its associated lore, set within the grimdark universe of the 41st millennium. Located on the planet **Koronus**, Roostock is a sprawling, industrial metropolis built atop a massive, floating platform known as the **Roostock Sky-City**. The city is a testament to the Imperium of Man’s engineering prowess, though it is also a symbol of the grim realities of human survival in the far future.

The Sky-City itself is an enormous, reinforced structure held aloft by powerful **gravitic lifts** and **anti-gravitic fields**, allowing it to hover above the planet’s surface. Below, the planet’s surface is largely uninhabitable due to extreme radiation and hostile environmental conditions, making Roostock a critical stronghold for the Imperium. The city is densely populated, housing millions of citizens, including Imperial Guardsmen, bureaucrats, and various support personnel. Its architecture is utilitarian, with towering spires, cramped living quarters, and vast industrial complexes.

Roostock serves as a key administrative and military hub, housing the **Roostock Garrison**, a regiment of the Imperial Guard tasked with defending the city and maintaining order. The city is also home to the **Ordo Xenos**, a branch of the Inquisition dedicated to hunting down heretical and alien threats. Despite its strategic importance, Roostock is not without its problems. Crime, corruption, and the ever-present threat of xenos incursions or heretical uprisings create a constant state of tension.

The city’s name is derived from its unique construction, with "Roost" likely referencing its elevated position, akin to birds perched on a high vantage point. Roostock appears in various *Warhammer 40,000* sourcebooks, novels, and game supplements, often serving as a backdrop for political intrigue, military campaigns, and larger-scale conflicts within the Imperium. Its isolated yet vital role makes it a compelling setting for exploring the struggles of humanity in the face of an endless war against the unknown.
