A super-structure built to oversee a city built by the Kah'Rul, the Citadel is a tall standing monument. Filled with technology nodes and chambers, the Citadel provides one of the most fortified wall systems on Earth, containing a complex city system.
Upper Level
The highest point of the Citadel is build up the side of a mountain range, embedded in the crest between two summits. The mountains provide natural protection while the wall below creates a nearly impenetrable encasing with optimal range for threat detection.
Middle level
Mostly large flats of metal and cement with a few structures here and there, the middle level of the Citadel is for ship/carrier landing/storage and troop assembly platforms. From this level, troops can be housed and assembles in a moment notice for deployment and mass briefing gatherings.
Lower Level
Primarily factories and assembly plants, the lower levels are where the inhabitants of the surrounding city come to work on parts and modular assembly. This method keeps them from being able to interfere with the equipment intended for use by the Kah'Rul.
City
Still within the protection of the wall, the City is a slightly maze like housing area for the inhabitants with no rank or stature. Here, Peace Keepers will patrol and ensure Denizen compliance.
