Myumbiae AA-A h3 has earned the name Cthulhu's Slumber for the nightmares that await the unwary traveler. The system holds impressive vistas, several of which double as navigational hazards. Pilots should use caution while visiting these attractions.

The system's central star is a 46 solar-mass black hole, requiring Commanders to zero their throttles either while in hyperspace to the system or immediately after exiting hyperspace if they wish to avoid a collision. The black hole itself provides an amazing panorama, refracting the Milky Way and tens of thousands of blue-white stars within the crowded Elysian Shore.

The system's neutron star is a 0.71 solar-mass body with three distinct rings. Pilots are advised to approach with extreme caution due to the radius and low visibility of the outermost ring. It extends from 62 light-seconds to an incredible 250 light-seconds. The middle ring begins about 1,000 km beyond the inner ring and extends to 2.7 million km. The innermost ring begins 100 km from the star's surface and extends to about 172,000 km. The A and B rings are rocky while the C ring is metal rich. They contain 0.012, 2.98 and 64.7 lunar masses of matter, respectively; for comparison, Earth comprises about 81.3 lunar masses. Particularly dedicated pilots can scan the A ring to find an alexandrite hotspot, though this requires avoiding the ring and diving perilously close to the neutron star's exclusion zone.

The neutron star's rotation is also anomalous at a whopping 81.7 years. Possible explanations for this extremely slow rotation could include a lack of rotation in the star preceding its supernova and tidal interactions with its ring system. It's also possible that close interactions with the central black hole earlier in the star system's history could have slowed the neutron star's rotation.

Bodies 2 and 4 are both Class K orange-yellow stars with 0.55 solar mass and 0.66 solar mass, respectively. Each of these stars hosts a collection of rocky worlds, and while some of these planets have atmospheres, none have any form of exobiology. Bodies 2 a and 4 a each have volcanic activity owing to tidal forces from their parent stars.

The planets around each of these stars offer good views of gravitational lens effects around the black hole, though these pale in comparison to the view near its exclusion zone.
