There would be something of a cultural renaissance following the wide release of Kendall Stone's documentary about the potential Cheimeron surrender. The documentary became a huge hit, and quickly spawned an enormous number of tangentially related jokes and one-liners.
Unrelatedly (but very much as part of that cultural climate), a new social network sprung up, with no official name but known colloquially as SevenThree, in the immediate aftermath. Quickly it gained a massive monopoly across the system, and its influence reached into others too. It is suspected by some historians that this was a major contributor to the Mass Unification of Kybele, due to its anonymity and end-to-end encryption. This allowed massively wide, confidential inter-clan and even inter-system communication. Kendall Stone himself found a new type of fame on this platform, leaning into the frequent jokes made about his presenting style and impressing everyone with a few very well-executed public pranks. It is rumoured that, to pull them off, he frequently uses time travel (which is, as you know, very much illegal).
At first, of course, you had clans using the system to organise turf wars, but as the Unification progressed it increasingly became a locus for inter-clan communication and understanding. Usually this would be achieved through very opaque jokes and images. Running jokes on the platform would be understood across cities, planets and even entire systems. Though still Kybele's worst-kept secret, it looks as though the platform is about to make a major splash across the galaxy, with celebrities on Achelia known publically to use it.
Perhaps as expected, counter-culture took a remarkable turn in the years following. The Tungsten Roses had decamped in large numbers to Kybele immediately after time travel was made illegal; there had been a healthy Achelian-Kybele exchange of people and goods for a long time, and this relationship strengthened at first.
As SevenThree gained traction, some major Tungsten Roses figureheads left to return to Achelia - straw polls in major Achelian cities suggested a feeling of disillusionment with the new Kybele culture. Still more Roses members, however, embraced the differences between Old and Neo-Kybele art and spun off into cultivating their own strange responses to it. And, as Kybele artists responded in turn, the cultural scene became increasingly weird, esoteric and dreamlike. To this day, understanding and critiquing the Tungsten Roses' art is considered a marker of very high intellect and taste.
Lucas and Lartius Ace (aka Gordon Fox, their shared name on Internet channels) are known across the system as two of the most skilled criminals in the galaxy. So much so, in fact, that “being Aced” is now a regularly-used slang term for corrupt politicians and police officers receiving their just desserts. The two of them are known for their intensely daring heist operations, near-telepathic ability in wordless communication, and completely awesome secret handshake. They continue to perform large-scale criminal enterprises to this day. Several anonymous but very large donations to inter-system charities have recently been recorded; it is suspected that the brothers are responsible.
