The exact nature of the Hierarchy's space faring technology is a mystery. All Hierarchy vessels are devoid of any semblance of instrumentation, apparatus or computer terminals for systems management and astrogation. The closest equivalent the Hierarchy has to a command bridge is a peculiar structure that is housed within the Archemperor's gargantuan flagship. The control room, for the lack of a more appropriate term to describe it, is a 7 kilometer wide chamber, consisting of 3 concentric outer corridors with a central chamber that houses a large spherical crystalline artifact set upon a dais at the center. The exact nature and function of the sphere is unknown, but it emits intense waves of beta and gamma radiation, immediately lethal to any unshielded organic lifeforms even from the outer corridors. Beneath the dais are massive heaps of biomass, filling the entire central chamber. In truth, the entire structure raises more questions than answers.
Present within the chamber is a seance of 6 tall beings, reported to be at least 9 meters tall each, congregating in silence around the sphere. It is clear that the massive scale of the chamber and the corridors are made for these beings, and are not meant to be traversed on foot although possible, considering how inaccessible the central dais is to grounded creatures. These beings known as Navigators, share a single mind, and they act as the crew of the ship's command bridge. Beyond that, not much is known about how they influence the entire vessel other than the fact that they constantly perform rituals around the sphere.
One thing is for certain, it would be nigh impossible to hijack or commandeer a Hierarchy vessel considering how "proprietary" their methods are. It requires a certain level of macrocosmic agency of the mind in order to operate Hierarchy technology.
