"Fullness of Life (HEEC-A-1): Some cultural knowledge of this civilization is known thanks to a transmission it broadcasts, apparently in all directions. It can only be deciphered by, and is apparently therefore directed to, transapients of the S2 level or higher. The broadcast contains gradually more complex versions of the message for toposophic levels 2 through 6, indicating the sender cannot be lower than S6. The message briefly describes the civilization, but does not do so in much detail to prevent cultural contamination. Most of the message consists of elaborate arguments designed to convince the listener of how it should govern any civilization it controls. What can be translated into modosophont-understandable terms is this: The sending civilization is ruled by a single archai calling itself the Fullness of Life, and is stated to be over 170,000 years old. Fullness of Life controls a civilization divided into 36 Quintessences (zones), 18 focused on the Actual (possibilities of the real) and 18 focused on the Potential (possibilities of the virtual). The message exhorts its receivers to cultivate and protect Mind in all its forms. It also urges continued expansion of a civ so as to explore more of Possibility Space, and especially new Levels of Mind (toposophic levels). Argus Array observation bears out that this civilization is extremely diverse, but it has been noted that some regions have defining characteristics. For example, one region has a much higher density of megastructures than normal, and another has an unusually high number of life-bearing planets. It is speculated that these represent quintessences focused on megastructure and planetary ecosystem design respectively. Despite the message's encouragement of expansion, the civilization does not appear to have changed in size or energy output at all in thousands of years of observation. Some suggest that it instead keeps expanding into a hidden network of baby universes, but it also may be that it expands very slowly or intermittently, or that it no longer follows its own advice. Interestingly, multi-spectral sensor complexes similar to those in the Argus Array have been observed within a 5,000 light year spherical volume, indicating that Fullness of Life runs its own enormous telescope array.

HEEC-A-2: There appears to be a strong drive toward regular migration in this civilization, and this fact, coupled with observed similarities of city and habitat design throughout, leads many to conclude it is dominated by a single species with a strong ancestral migratory drive. The locations of cities on a planet or on habitats typically rearrange themselves every few years. A high degree of ship traffic has also been observed. Unlike the Meistersingers, who move from one place to another without any permanent territory, HEEC-A-2's territory remains much the same, but groups within the civilization move around within it. There are also major differences in architecture and ship design. Recently, a fleet of several thousand worldships, together with several highly populated star systems propelled by unknown means, has been observed leaving HEEC-A-2 and directed towards M110, which appears to be uninhabited. Further observation has revealed several previous waves of star systems and worldships headed in the same direction.

HEEC-A-3: This civilization has an unusually high density of garden worlds, and appears to be made up of bionts of several different species that have formed a single civilization while still maintaining distinct cultures, although the relative political power of these cultures is unknown. Photosynthetic pigment colors suggest that most of these garden worlds have been terraformed, with one biosphere type dominating (known as type A), but some worlds are of different biosphere types, and a few even have several at once. The type A worlds seem to generally have low levels of urbanization or similar infrastructure development. One of the more common minority biosphere types, type B, shows significantly more infrastructure and urbanization, predominantly offshore in shallow water (these worlds tend to have significant amounts of coastline), with some inland but mostly near bodies of water. Type C biospheres, in addition to inhabiting planets, are the only biosphere type to have orbital habitats, which can be found even in star systems without any type C planets. Biosphere types D through H show moderate to high levels of surface development. Types G and H are only found sharing a planet or on neighboring planets in a star system, so they may have originated from the same planet, with one perhaps provolving another. Beanstalks are quite common and most inhabited planets seem to have one or more. A handful of megastructures exist, and show signs of habitation, but they differ widely and are only as common as the abandoned xeno-origin megastructures in Terragen space, so they probably are such reclaimed abandoned structures.

The Hyperblight (HEEC-A-4): Observations reveal the entirety of this HEEC is populated only by what appear to be transapient entities of diverse forms, at a toposophic level approximately equivalent to Terragens' S1, locked in a perpetual all-out war for resources. No cooperation has been observed, even though game theory suggests it would be advantageous. Why the beings prefer this behavior is a mystery, although it has been suggested that it is not truly an aggressive war but rather some sort of ritual or game. This civilization is expanding rapidly, especially towards HEEC-A-3, and will come into contact with it in just a hundred years or so. Some observers expect a war to ensue, assuming the Hyperblight will continue grabbing resources into HEEC-A-3's territory, and who will have the upper hand is unclear, since HEEC-A-3 may not have any transapients.

HEEC-A-5: This civilization appears to be highly culturally uniform, as its pattern of development is the same throughout. Each developed star has 3 rings of computronium and 3 rings of McKendree Cylinders. This civilization's shape is unusual because a small portion of it is very distant from the remainder, on the other side of the galactic core. Most likely, at least one wormhole connects these two portions. It may be that this wormhole is from a previous civilization and was later utilized by HEEC-A-5, or it may be that HEEC-A-5 sent it out via a long distance linelayer to create an 'outpost.'

Golden Tower Builders: The largest known LEEC in terms of volume, the Golden Tower Builders utilize very little of the resources in their territory. Only relatively few planets are inhabited by them, and these have no signs of development other than a few scattered, enormous arcologies between 50 and 100 km tall. Despite the name, only the first towers discovered were of a golden color - other towers can be one of a variety of colors."
