Been a while thinking on this as I wanted to play them a bit first. But best post it before I forget! -zzzZathabarrr
The Snithereal home-world was a place of contradictions, violent deadly contradictions. With the planets axis nearly facing their parent star. Hellish heat and frozen wastes vied with each other for harshness.
With unlimited heat to warm them, the early Snithereal throve in the humid twilight band around the equator. Rising from a simple predator, to an integrated and highly technical species. Mastering technology to keep them warm in any conditions they first subdued the dark half of their world stamping out any life form that might have also risen to challenge them with a calm indifference. Centuries later they considered the twinkling stars above them with an unblinking, hungry, gaze.
The First Ravening - Early Expansion
With the discovery of the first Warp drives they Spread from the Nestworld, ruthlessly devouring worlds leaving no higher life form alive to challenge them. Who knows how many potential space-faring societies and races disappeared in this cold emotionless advance of destruction across the stars.
Then they met the “The Metal ones” Baffled by this chance meeting with hyperintelligent cybernetic creatures, that they could not consume, and could barely match in technology, there advance was halted. Nursing their first real setbacks they redoubled there efforts to refine their technology, developing the multilayer ablative scale like armour that is a trademark of their vessels.
Eventually this false war petered out. The two species shared very little in common, and even the most belligerent Snithereal saw less and less sense in fighting creatures that could not be consumed and worlds too usually too cold for easy conquest. However, seeing the metal ones successful use of slave species in their own war efforts: the Snithereal reevaluated their indifference to other creatures.
The Second Ravening - Conquest and Enslavement
Exploring a little more cautiously, they catalogued and analysed new intelligent creatures learning much from these hapless civilizations. The Great Queens determined some could remain as useful slaves. Unless they were needed for the next mating season of course. No longer under certain sentence of death, races instead lived in fear that at some day their lives would be demanded as well as their labour!
Eventually their rapaciousness led to the great dispersal. United together, a band of their oppressed sub races managed to smuggle a cryonic bomb onto the Nestworld. The bomb overloaded the Photonic shields erected in the heart of the great dessert where the crown city lay. Millions of Snithereal were slain as the searing heat swept in, including all the Ancient Queens that formed the governance of the race.
The War of Queens - Civil war and dispersal
Of course younger Snithereal Queens existed off planet. They lost no time in pressing their claims of seniority by Age, or blood, or influence. For a century the Snithereal preyed largely upon themselves as they squabbled for power: much to the relief of the universe.
But all such conflicts end and a victor was eventually chosen as the the Great Queen, and once again the far flung coils of the Snithereal are reaching outwards to the greater universe.
But perhaps this time the universe is ready…
