This is purely speculation but based on a solid foundation and stemming from a conversation on our comms relay.
The Triglavians use a lot of terminology that appear foreign to our ears and a number of proper names, which don’t appear to conform anything familiar.
Analysis of the Triglavian language is possible by using the same techniques as historical Linguistics, this has been used extensively within the Minmatar Republic for research into the movement and relatedness of the various tribes. The terminology used by the Triglavians seems to be, at least in part some form of archaism, as evidenced by diachronic linguistics. Meaning that some of the words they use resemble terms that formed the foundation of words that we use today. A Synchronic analysis of the Triglavian messages seems to indicate that they use a more symbolic form of expression, some terms change their meaning depending on the context of the message. All the people of New Eden share a lot of DNA, to the extent that we are all very similar at a base level and this has long been held as proof of our common origin, along with elements of language as well. From the elements of the Triglavian language it is fair to say that they also originated from this common stock. Scholars are working on the etymology of their archaic language and, while some terms appear to be unique, there are others where they can be split into recognisable fragments.
From early results I feel that we may be able to get a better picture of their society. The Koschoi/Narodnya/Navka enigma for one. The general aim of Triglavian society is to produce some ideal according to a scheme to winnow out weakness; everything has to be proven of value and in line with their moral code. This is what they refer to as the Struggle.
I was reminded of an old tale, its origins lost to us, and one I barely remember from childhood. It concerned a society where in order for a person to earn a name they had to kill some animal or perform some task of great value to the tribe. We attach great importance to names, our sense of identity can revolve around it. So it is not out of the question to assume the Triglavians do the same. Names like Zorya and Kresnik. The Koschoi, from what we know is some kind of authority, and the Navka references the past. It is very evident in the corruption incident intercepted by the Semiosis modules. There has been a lot of specualtion about their nature, but it might actually be relatively simple in comparison with some ideas, even ones I, myself, entertained.
The Flow appears to be some great repository of knowledge, things are uploaded to it and they store their decisions on certain matters there and refer to it for historical context, as in reverse-time. What if the Narodnya, which is now taken to mean the common people are the ones actually involved in the Struggle. The Koschoi supervise them through some kind of infomorphic link, I did think it might have been the case that they were actually hosting two infomorphs in the same clone, which is theoretically possible, but this would be easier and safer for the Koschoi, retaining their immortality. The Navka, and I am pretty certain their is only one, is some kind of software agent; an expert system that is able to search their knowledge base and come up with historical data. Which would mean that Zorya and Kresnik are Koschoi individuals who have won their Struggle and as such part of the Convocation of Triglav Ouside the Struggle. The Zorya ships we see, are not actually piloted by Zorya, but use a fit designed by Zorya. That to me makes perfect sense.
