Calixis

Calixis is a sector in the galaxy of the Warhammer 40,000 universe. It is located in the Segmentum Obscurus, a vast and largely unexplored region of the Imperium of Man. The Calixis Sector is characterized by its numerous worlds, many of which are industrial hubs, agricultural worlds, and military outposts. Its strategic importance lies in its proximity to other key sectors and its role as a bulwark against xenos incursions and internal rebellions.

The sector is governed by the Adeptus Administratum, with the ultimate authority resting with the High Lords of Terra. However, the day-to-day governance is often handled by sector governors and planetary administrators, who are responsible for maintaining order, collecting tithes, and raising forces for the Imperium. Calixis is known for its strong military presence, including numerous Astra Militarum regiments and elements of the Adeptus Astartes.

The sector has a long and often tumultuous history, marked by numerous wars and conflicts. It has faced threats from various alien races, such as Orks and Chaos forces, as well as internal uprisings and heresy. Despite these challenges, Calixis has remained a loyal and vital part of the Imperium, contributing significantly to its vast war machine and economic output. The sector's diverse population and varied planetary environments contribute to its unique character within the Imperium.
