Hmm. I feel that I should write more. Okay.
The Jairaekt practice a strange science based zealousism, lighting ancient pyres with blue torches of plasma and choosing to fight and kill with staves of magnificent alloys in ceremonial fashion. Scientists are revered often being thin and lanky, their shells spotted with a blue gray, similar to smoke, pattern with short, thick tufts of black hairs and considered priestly and mysterious.
Assassination is considered legal as long as it is practiced with no ill blood using the proper bureaucratic channels, and paying the debt of course. This practice is as ancient as the cycle of war and is how every cycle begins. A massive amount of assassinations are committed between houses beginning a war.
Precision and capture is stressed, most wars result in little structural and informational damage due to specific methods of architecture and datacaching seeing as no one wants to wipe out everything. This practice carries over into most tactics in combat, trying normally to capture the enemies ships, colonies, or stations, rather than obliterating them, most would in fact consider this action rude and worse than retreat or decimation.
Consistent overcrowding has made the push to leave the planet very strong in the last century leading to the discovery of ftl. Small arms are very progressed but ship to ship weapons (beyond the suicide cannon) are few and far in between. That is to say they are not popular, these technologies occur but only in specific occasions have heavy mining equipment and scientific machines been repurposed fir destruction. These cases have been archived and could be used... If the situation absolutely required it.
