Cadia

Cadia is a terrestrial Fortress World on the edge of the nebula known as the Eye of Terror. Cadia's natural environment is similar to Terra's, with a large Ocean covering 70 percent of the planet. The land mass that does exist is divided between incredibly thick pine forests and vast glaciers. The planet is slightly cooler then most but not to the point that it adversely effects growing conditions. Cadia was settled sometime in the early 32nd millennium by Humans, who quickly became the dominant species. Cadia's proximity to the dangerous Eye of Terror has made it necessary for the people of Cadia to fortify the planet. After the first chaos invasion soon after the planet was settled cadians cities changed from a plan of broad avenues to one where the streets of its cities arranged in zig-zag patterns meant to make any intruding enemies fight for every block. It is here that Abaddon the Despoiler, Warmaster of the Chaos Legions, brings down his continual assaults or Black Crusades from his hold in the Eye of Terror. At the heart of each cadian City is a fortress or castle called a Kasr in the local dialect. The Largest Kasr in 241.M41 Was Kasr Derth. Cadia is the home of the Imperial Guard Cadian Shock Troopers regiments, widely regarded as the best soldiers in the Imperium short of the superhuman Space Marines.
