Historical Civilizations

Throughout the Silky Way and it's satellites numerous remains, records, and ruins of bygone civilizations perpetuate the faint echoing memory of these long deceased lifeforms and cultures to this very day. The following database provides us with brief accounts of their former societies and legacy's left behind.
=== Star-Engineers ===
The Star-Engineers (real name unknown) were one of the first lifeforms and civilizations to arise in the Silky Way. Almost nothing is known about them, and their very existence is only a hypothesis, albeit a strong one. The extent of their civilization is unknown, but almost definitely Silky Way-spanning, as their one and only relic, the Cerlus Cluster had to have its million stars imported from somewhere. In addition to that, certain chemical signatures and elements that only form in local areas of the Silky Way can also be found in the Cerlus Cluster.
The Star-Engineers are speculated to have had a deep reverence for life, or possibly a benevolent god-like attitude towards it. They assemlbed one of the most fertile regions in the galaxy for life to form and expand into civilizations. Truly, outside of the Cerlus Cluster, it has been said that it is "ten thousand times harder to thrive."
=== Olorand Stellar Authority ===
The Olorand Stellar Authority was the first documented civilization in the Cerlus Cluster. Its inhabitants were primarily thick grey colonies of cells, the largest reaching sizes of up to ten meters across. They resided in habitats between and around the stars, for unknown reasons, but this is the primary reason why we know about them. Their buildings have been drifting miraculously between the stars for a billion years, untouched. They used trinary code for their computers, which, in all honesty, look quite similar to them, and their main method of propulsion was chemical exhaust drives, though many times more efficient than primitive ones. 
Their fall was the result of a supernova in the space they resided in. It sterilized their habitats, and killed off any of them who tried to escape. Within a few decades, every last one of them was dead. 
=== Builders of the Cache ===
Nothing is known about this civilization, except that they built the Cache of the Ancients, and so had to be cluster, or even galaxy-spanning. Apart from that, we know nothing. 
=== The Society ===
The Society was a militaristic and expansionist civilization employing biotechnology and nanotechnology to spread throughout Cerlus, and gained small footholds elsewhere before they were wiped out. They evolved on the Cache of the Ancients, and spread out quickly, conquering most of the Cluster for their dictator. The colonised and terraformed many worlds throughout the stars of Cerlus, setting the stage for further life to develop down the track. It is largely due to them that Cerlus is so vibrant right not - not even the Star-Engineers could have influenced Cerlus this far down the track to be this lush.
However, The Society overstretched itself. It began to seek footholds in places outside of Cerlus. Societal ruins and artifacts have been found in the Core of the galaxy and the Rim, showing how far their empire spread at one point. But it wasn't to last.
An invasion from a Dark Forest Empire wiped out the Society extremely quickly. Evidence suggests gamma rays and neutron stars were a primary weapon, sterilizing worlds and systems and killing all of the people in the Society.
Before they all died, however, on a thousand worlds, the last vestiges of the Society conjured together a weapon that they intended to use against the Dark Forest Empire, as an act of revenge. Kildathu, as it is called, drew on vacuum energy and, with enough charge, could destroy functionally anything.
It has been charging for 800 million years.
=== Primaformes ===
The Primaformes were a gap civilization and once flourished throughout the local group extending itself across a considerable portion of both the Silky Way, Majestic Galaxy, and possibly the Asharbyel. Little is known about their biology but their technology and ruins have been discovered in over a hundred systems.
The Primaformes have not been definitively tied to a single event but speculation assigns them as the possible builders of Euclid's Expanse, the possible predecessors of the Komters and/or Alkerre, and the Vondunke consider them the first victims of the legendary monster Klathtar.
Aside from Vondunke lore and other speculations, the cause of the Primaformes disappearance is due to an unknown means.
=== Were ===
The Were, literally from the Vondunke word for "were" as in "They were and are no more", They once existed, alongside the Dthalvans, as one of two newborn races in Majestic Galaxy roughly ten million years ago. They are considered possible relatives of the Olerre, Pelarri, and maybe even the nYaucto.
Shortly after they spread across the stars the species was destroyed along with the Dthalvans in the supernova, dubbed "the doom at the dawn" which took place within the Nebula of Oblivion. The race may have survived Ary, a term for radio sources originating from the outer Majestic Galaxy in the Çilae Shoal.
=== Dthalvans ===
The Dthalvans was a species which existed roughly ten million years ago in the depths of the Majestic Galaxy. They are the known primarily for their descendants the Crystalophore which abide in the said galaxy's Choir Nebula. They were a form of living crystal, eventually finding their way into space. And though they could not reproduce in the nebula's void they could survive and traverse the relatively denser space of the Oblivion Nebula.
The Dthalvans met the same fate as the Were in the enormous supernova which light up the otherwise intrinsically dark Oblivion Nebula dispersing a large part of it among the rest of the galaxy. However a remnant survived to form Rei.
