- Aardwolf - Text by Steve Bowers
- Abraxas - Text by M. Alan Kazlev
Autonomous Sophic League habitats in hinteregion MPA space. Originally founded, during the later Second Federation period, and inhabited by the Young Jungs, who established schools of esoteric learning there for thousands of years. After their collective transcendence (or "Individualization") in the post-ComEmp period, the habitats were increasingly given over to eccentric clades and micropolities of all sorts, especially those with unconventional philosophical beliefs and practices. The region has settled down a lot in the last thousand years, with the old groups becoming conservative and mainstream, and the young bloods migrating further outwards to seek their destiny.
- Abruzzen - Text by Anders Sandberg
Solar Dominion world notable for being the lowest world of the Dominion relative to the galactic plane - in 3644 the famous explorer Killavan Yu-Tang set off from here on a long-range survey of the galactic disc.
- Abydos (Cor Caroli) - Text by Anders Sandberg
The highly magnetic A-Class star Abydos is a useful source of magnetic energy.
- Adonis - Text by M. Alan Kazlev
Sophic enclave in the Perseus Arm, fallen to the Amalgamation in 8761.
- Adorate - Text by M. Alan Kazlev and Anders Sandberg
Sophic enclave in the Perseus Arm, fallen to the Amalgamation in 8761.
- Ahreemi Meetpoint - Text by Todd Drashner
Asymptote civilization aligned loosely toward the NoCoZo. Located in a multiple star system some 3000ly from Solsys in the direction of the galactic core. The system consists of 6 stars in 2 binary pairs and 2 singles in a rough cross. A 0.5 km gauge wormhole has been constructed using what was once the 7th star of the system. In addition four gas giants that had orbited the star have each been converted to a number of 100 m gates. The system supports a diverse population of tweaks, baselines, provolves, vecs and aioids and major computronium banks for three archai (The High Triune). Total population 350 billion.
- Ain Soph Aur - Text by Todd Drashner
One of the most advanced and heavily developed systems in the Inner Sphere.
- Akasha - Text by M. Alan Kazlev
Important system in the Pleiades volume, founded by Nuage tweaks.
- Akirate - Text by Anders Sandberg
47 Ursae Majoris. Solar Dominion Inner Sphere world, center of heterodox Stevens clade. It is close to Fons Luminis but lacks terraformable planets due to a gas giant in the wrong orbit. Instead extensive orbital settlements extend throughout the system.
- Alauda - Text by M. Alan Kazlev
Minor NoCoZo world with wormhole links to Vast Endeavour and Frei. A wormhole link directly to Merrion is intended to arrive shortly in the Bazaar Project, which will render the Alauda link obsolete, something the local merchants are not at all happy about!
- Albireo - Text by M. Alan Kazlev
(Beta Cygni) Double star in the Cygnus Inner Quadrant, developed by a number of superbright and po clades.
- Alcor and Mizar - Text by Steve Bowers
These two star systems in the Plough are an important point of contact between the Solar Dominion and the Solipsist Panvirtuality
- Aldebaran - Text by M. Alan Kazlev
- Aleph Absolute - Text by M. Alan Kazlev
Cluster of star systems in the Keter dominion, site of the largest archailect concentration in known space. Over the last 7000 years the Aleph intelligences have converted all available matter into computronium, creating diamond lattice habitats for more AIs, infovores and virtuals than anywhere else (a rough estimate implies over 10E8 trans-singularitan entities). Due to the extreme speed of individual and cultural evolution, together with the vastening effect, the Aleph cluster has little interest in external (even Keterist) politics or trade with bionts.
- Alexandria (Tichy 44-III) - Text by Anders Sandberg
Middle Regions system, known for its vast libraries and archives. Part of the Negentropy Alliance.

(See the Brain Shell.)
- Alpha Centauri A+B - Text by Steve Bowers and John M. Dollan

- Anahita - Text by M. Alan Kazlev

- Audubon - Text by Steve Bowers
Arean-type planet colonized during the First Federation period.
- Avase - Text by M. Alan Kazlev
Minor NoCoZo system, Centauri sector. Its only claim to fame was the battle of 5502, where PCO forces scored their first victory over the Paradigm and turned the tide of the war. The system is currently home to a patriotic but otherwise irrelevant culture that trades in nanocloned war memorabilia, medals and PCO fleet uniforms, and speaks of the day coming soon when they will "finish the job" and "whip the Paradigm's butt".
- Aw Addia - Text by M. Alan Kazlev
Third planet, Van de Bos' Star. A regional power and an important centre of trade and learning. KoHold City is home to the headquarters of the Exopaleoarcheological Institute.

- Barboro - Text by M. Alan Kazlev
BD -16°6046; one of first Keterist worlds to be established. Location of the Unerk-Pr!fok, one of the largest collections of Perfect Art. The legend that the great MPA philosopher and fabulist Kemshola was transmuted into a perfect artwork at Unerk-Pr!fok is considered unlikely by most historians.
- Barnard's Star - Text by Anders Sandberg
Surrounded by extensive asteroid belts, Barnard was one of the first systems to be colonised by the First Federation. Some nanotech window and nanodisaster era belt colonies had also colonised the disk, but due to the lack of volatiles their habitats could not expand much. Barnard became an important stepping-stone in interstellar colonisation but always suffered from the lack of volatiles. The adventures of the Kuiper-belt surveyors (the "comethunters") and the Water Wars remain classic stories.
- Baryos - Text by Anders Sandberg
Baryos is an unique planet, if that is the right term. It was first discovered by Ylli Farscapes, a NoCoZo remote exploration corp in 7522. They believed, led by stellar motion observations, that the system consisted of a silent black hole orbiting with a sun-like star. What they discovered was much stranger: where the black hole should be a terrestrial planet orbited, with an apparent mass equivalent to 3 sun masses.
- Barzelona - Text by Steve Bowers

Former Negentropy world, currently Efficiency Maximization Paradigm dyson sphere, used for energy production. A major information center, at its height housing the famed Budrosa Repository and the Centaurus biological archives. Attacked by the Paradigm and optimized in 5424. It became a central staging point for the Paradigm crusade, and all planets were dismantled to build a Dyson sphere and fractships. as part of the Jekaumeatrine Accords the Paradigm released copies of the the Repository, the uploaded biological archives and 263 million citizens, which were later restored at Alexandria and Ken Ferjik.
