Monolith

The Celestial Gates was a  that orbited the planet Mure. A taking the form of a hollow, the Gates superstructure was originally constructed by the Celestials to protect Mure's  settlers from  by generating a constant artificial  capable of encompassing the planet.

The station also possessed a series of independent s which could be activated to fill the 32 hexagonal and pentagonal gaps in the superstructural frame. These shields were used to disintegrate incoming asteroids or other cosmic debris that littered the Seven Deaths system and could also be used to defend the planet from outside attacks.

Design and placement
The Celestial Gates megastructure was a hollow possessing a total of 32 hexagonal and pentagonal gaps between the enclosing edges of the frame. The frame itself was composed of several hundred stacked levels arranged in a radial layout to take advantage of natural. In addition to Mure's own gravitational pull on the station, the lowest level of the station, that closest to the planet, hosted many experimental Celestial to ensure the station's occupants felt comfortable traversing the megastructure. As the of the structure was roughly, the curvature of the floors was largely unnoticeable, allowing for the residents to import standard planetary amenities such as furniture without the need for custom designed alternatives.

The station sat in the planet's. Due to its location, the station experienced some but still retained the benefit of the planet's naturally generated gravitational pull and Force aura. To ensure it remained at the optimal orbital distance at all times, the station was equipped with a multiplicity of s scattered across the entirety of the station that allowed for minute adjustments to orbital speed and distance.

Construction
The Gates superstructure was constructed of an early Celestial version of and. The raw materials necessary for the creation of the Gates were obtained from the extensive asteroid field that lay within the confines of the Five Deaths system, the ruins of the ancient planets that once existed in the system prior to its expulsion from the region. The parts themselves were assembled onsite by Celestial refineries and factories and towed into place by fleets of starships.

The outermost layer of the, that exposed to the vacuum of space, was shielded in an extremely thick   capable of resisting s.  (GCR) was a form of  primarily composed of  and s from heavy elements like lithium, beryllium, and boron accelerated at speeds nearing. The Celestials often plated their vessels and space stations with a -heavy -based nanomesh to resist this radiation. However, this method was insufficient to protect against intergalactic cosmic radiation (ICR) found in the extragalactic space of the Five Deaths system. Far removed from the galactic plane, ICR particles were unaffected by the galactic magnetic field and were thus powerful enough to tear through the atomic substructure of any materials in their way, including conventional Celestial plating. The fragmented remnants of these destroyed atoms were referred to as "secondary radiation" and were extremely deadly to biological organisms.

In response, the Celestials created a trielemental nanocomposite compound with which to shield the Gates' metal superstructure. The stable  of nitrogen and boron, both heavy elements capable of absorbing and deflecting secondary particle radiation, formed the basis of the nanotubular structure. The gaps between tubes were filled with molecules, whose single proton and electron composition was large enough to deflect the protons and neutrons of the ICR particle wave. Together, the material was able to successfully block a large percentage of intergalactic cosmic radiation and was thus applied liberally to the outermost layer of the superstructure.

Deflector shields
The Gates possessed two different types of, and. Each of the 32 hexagonal and pentagonal gaps in the superstructure representing the sides of the truncated icosahedron structure could be independently sealed with these shields, which could be run in tandem or solo with varying levels of intensity.

The ray shield was the primary defense field of the Gates, initially installed to protect the planet Mure from the dangerous intergalactic cosmic radiation that pummeled the Five Deaths system every second. With the completion of the Gates, the ray shield was run nonstop for the next several dozen millennia. However, the shield's lowest setting was sufficient to repulse such radiation, requiring minimal energy and rendering the shield passable for solid objects like starships. At higher settings, the shield could absorb the energy from barrages and prevent enemy vessels from passing into Mure's upper atmosphere. At its highest settings, the shield could withstand extended s barrages from a fleet of before burning out.

The particle shield was the secondary defense field of the structure, protecting the structure from physical threats. It was most commonly used to intercept and disintegrate incoming asteroids from the Five Deaths' extensive cosmic debris field composed of the remains of the systems' former planets. It could also be used to block the entry of enemy ships into the Murec atmosphere, much like the energy shield. At its highest settings, the shield was capable of withstanding a barrage of s.

Factories and refineries
Maintenance of the facility was undertaken by the Celestials's automated repair systems, similar in design to those reverse-engineered by the to maintain the  and  for countless millennia. Required replacement parts were assembled from raw materials retrieved from the Five Deaths' extensive asteroid field and converted into usable compounds by the station's onboard refineries. The parts were then printed by onsite factories and automatically installed by automated systems. Even with the station's abandonment for a period of 12,000 years during the Murec dark ages, the automated systems continued to function as intended.

The factories of the Gates could be converted to military usage, capable of producing droids, starfighters, and capital ship components. However, its output was nowhere near as high or as efficient as later structures specifically designed for military applications, such as the Star Forge and Foundry. The Gates' reliance on asteroid resources rather than direct solar power was a limitation, requiring significant time and energy to round up the raw materials from suitable asteroids and refine them to a usable state.

Defensive systems
The outermost layer of the hull was punctuated at frequent intervals with outerward-facing batteries, estimated to be in the thousands. The barrels of these guns were also reinforced with the same hydrogenated boron nitrode nanocomposite that covered the hull, with small s plugging the resultant s to protect operators from radiation and the vacuum of space. In addition to these, the remaining levels of the structure contained thousands of turbolasers of their own, with complete coverage of the hexagonal and pentagonal gaps between frame edges.

The lower levels of the structure contained extensive starfighter hanger bays and capital ship maintenance facilities capable of fielding a large navy in defense of the planet. In addition to a navy, the entire structure was policed by a small army of guardian droids who regularly wandered the corridors, facilities, and residential complexes.

Power requirements
The entire superstructure was a massive power drain requiring extreme amounts of energy to run. Between the life support systems, gravity generators, magnetic field generators, deflector shields, automated defenses, material factories and refineries, directional thrusters, and other assorted systems, the Gates devoured many times the amount of power required to run other contemporary space stations of note, including the Rakatan Star Forge and Foundry. The Celestials developed the Gates to rely on, installing millions of unobtrusive solar panels to the Gates superstructure's outer hull. Reserve power was provided by a series of s, though these were not generally used except in cases requiring the use of higher deflector shield settings over a large radius.
