Deep within the Lychina System, a fortress of grandiose proportions has been hoisted, cutting through the red, radioactive haze of Baal, the home planet of the Blood Angels. The Arx Angelicum, the Fortress Monastary of the aforementioned Blood Angels, spanning over 50 kilometers of space, this monolithic bastion serves as the heart of the Blood Angels' empire, functioning as a trading hub, housing for the marines, and a factory to build only it's strongest machines of destruction. Within it are several batteries with an array of uses, though their primary used is to function as anti-air, they also have dozens of lance spires, capable of shooting extremely powerful beams of energy at its enemies. However, there are not just guns, there are also layers of void shield, comparable to that of the Red Tear, ensuring that this will withstand any orbital siege from the enemies of mankind.
