Little is known of the culture, former civilization, and even biology of the skrandar species. Extreme xenophobes, they had little interaction with the species of the Worlds even post-contact. The destruction of their homeworld along with the rest of Skranpen (Charred Waste)’s1 inner system in the self-induced nova of their sun (on detecting the relativistic approach of the Serene Fleet) has left little archaeological evidence available for study. Even the name of the Skranpen system, like that of the species, is phonemically generated and institute-assigned. What little is known of the skrandar is based on abstractions from damaged and disabled examples of the skrandar berserker probes and the two identified replication sites captured in the Exterminomachy.
What has been extracted from these sources (see declassified reports tagged PYRETIC PHAGE) suggests that the skrandar were in the grip of a peculiar type of madness at the end. It is believed among crypto-archaeologists that the skrandar had a preexisting cultural obsession with the Precursor Paradox: namely, why, when we see evidence of elder races and Precursor civilizations aplenty, and both life and intelligence appear to be relatively common within the Starfall Arc, has the galaxy not been colonized and/or hegemonized long since by ancient civilizations?
(Indeed, given the relative isolation of the Skranpen system, this paradox must have weighed even more heavily on the minds of the skrandar than on those species which originated in more populous galactic neighborhoods.)
The leading hypothesis, therefore, is that xenognosis came as a severe trauma to the skrandar; upon seeing the impossible, in the light of a presumed filter preventing starfaring civilizations from existing, they collectively went mad. If, they reasoned, there was – must be – some reason for the destruction of starfaring civilizations, then they themselves could only escape that fate by becoming that reason. And so they turned as a species to the manufacture of berserker probes designed to cull all other sapient, starfaring life.
It is easy for us today, looking back on the Exterminomachy, to attribute the tragedy of the skrandar solely to some inherent flaw in the species. But consider this: the skrandar were isolated, by their own choice. They had the opportunity, therefore, to go mad quietly, unknown to the rest of the civilized galaxy, hearing no voices but their own unreason.
For this reason, among others, the Exploratory Service at this time maintains its pro-contact, pro-intervention, pro-socialization policy towards emerging species. Whatever the short-term cultural impact of xenognosis might be, in the longer term, they very much endorse the view that an ounce of prevention today is better than a gigaton of cure tomorrow.
