General meaning: small triangles means Technology, Society, Forces(Military/Fleet) and Government, all bringing the big triangle forward, the (Vulpex) civilization, which is a equilateral triangle.

Vulpex is a friendly but militant species, they always maintain a naval supremacy around their space and galaxy, and the transfer ability made some of them fearsome pilot, because they can’t die with normal causes and can accumulate experience. Most of them are only going to“ascend” when their organic body succumbed to age or damage, though a redundant body along with binding process is expensive, and only a fraction of Vulpex have more than one redundant body. Vulpex is a species origin in a continental world. Endless strifes and conflict happens before the species is united around their atom age. Once they possessed FTL technology, they build ships which have habitat module and ftl drives and sent them to explore and settle in new worlds. Many of those ships have armaments, which was baptized by fire from stars to other empire’s plasma shots. But they survived, and the union begain it’s way of expansion while intergrate other species into it. Now the Vulpex have 10 gigantic ring world around 10 shielded and crypted system, each acts as production hub, ecological sanctuary and mega ship yard for the union. Alongside with entire galaxy’s planet and countless vulpex. Vulpex are extremely experience at building and maintaining navy. Their ship have excellent physical and energy protection, as well as it is extremely maneuverble, even their super capital ship. (Which only build on ringworld, and have length of diameters of some largest rocky planet. These behimoth can even cause planet wide seismic activity and tsunami even if they are in it’s lower orbit). Main weapons used by those ships are regular weapons, skipper railguns and tachyon beam, and usually tipped with AM warhead or thermonuclear weapons. Vulpex’s culture and society is an martial but friendly environment. People sometimes duel, but with different method, which is non lethal.
And the civilization tend to use unrestricted war only when necessary, most of the time when initial war goals were achieved, they will seek for discussion rather than continue the conflict. They have hybrid economy, which state control vital resources but free market for rest, especially consumer goods. For ships, multiple “State own” company(de facto private, since state only owns 15% of them) compete for bids using cutting-edge technology, so union will always have the best ship design.
In normal time, democratic system take place, but in war time or emergency, a military committee consist of 50 ascended Vulpex, who are the most experienced pilots, make descision.
