Being since the claming of the Mizar System the ruling dynasty, the european House Libra was always present at the Imperial Court and due to it's position always interested in the expansion of the empire.During the Great Holy Wars their ancestors fought on first line in battle, many of them with religious motivations, which is one of the reasons, why the libra became after the 5th millenium an important part of their rulership. It was mainly motivated by the selfless sacrifice of Lady Celestine Libra and the remainings of her fleet to stop the Great enemy's movement until the fleet of the Empire was ready to reunite and trap one of his fleets afterwards near the Mizar system, before it was able to reach the core worlds. According to later lords of the Mizar system it was a proof of those, who believed in the laws, given by Promethean Creed, as it is rumored that Lady Celestine's suicide command was motivated by higher motives for saving the emperor and humanity, since she was also known as a pius lady.
This belief was one of the main reasons, why Mizar became mostly a place, from where most lawyers and judges came from and why the highest concentration of criminals from the Old Worlds is located in the system. Three moons, the largest of them around the capital planet Protheon, have been turned over the centuries to pure prison cities, guarded by the Legions of the system and the fleet above them. Though conditions in the Mizarian prison camps are compared with the situation in the slaver systems more than attractive, prisoners on the moons have not always a good life and have to bow in front of the Legion's orders. At some periods of Mizarian history, even corruption among the guards had spread on the prisoner cities. Even today House Libra suspects that among their Legions still subjects exist, who abuse the lawful structures of the system for their own advantages.

The main industrial branch of Mizar was, independent from justice and religion, always focused on agriculture and the production of food.
Apart from persons, involved into the courts of the system and religious-motivated men or women, people who work in the industry are well seen and paid wealthy, as Mizar is dependent on the export of their goods. 1/3 of Protheon's total area is covered by huge farm districts, while the rest is mainly the city and the industrial sector.
Other planets in the system are more focused on farming and have small city areas, but due to the growing of population during the millenias, even those worlds are in danger of getting overcrowded.
Only few worlds like Pollux, which is classified as a pure mineral world and mainly inhabits the mighty dockyards of Mizar have not faced this problem, as they are either inhabited or serve as mineral worlds.
There are varios noble Houses existing next to House Libra, most of them being descendants of Libra. Only few of them like Scaleri and Descartes are notable, as the other counts have either high positions inside the courts of Mizar or are consulting the industry without having too much influence to the system.
Apart from the rulers of House Libra, the real controll over the Mizar System lies within the Military, the High Courts and the Food Industry. Since the courts are mostly controlled by House Libra, as it is also the House with the most Lord Justicars in history and the admirals and generals of the Military obey traditionally the noble family, only the industry has sometimes other interests than their overlords. For this reason, Mizar is also mainly profit oriented and always interested in closing contracts with legal institutes.
Not all too surprisingly, the current System Lord of Mizar holds again the position of the Lord Justicar. Though he is known as a loyal and fair man inside the ranks of the Empire, he also had faced a grave past. Especially criminals and corrupt men, who suffered from new investigations by the Mizarian Legions and Police to fight crime, have not already killed the wife of his first son, but also kidnapped once the Lord Justicar's grand-daughter - and though she was freed in time, the three-year old child unfortunately lost both her arms in the process.
During the next ten years after this accident, thousands of criminals and their operations were detected by the increased investigation protocolls and imprisoned and piracy around the system was nearly erredicated. Since these anti-terror-movements, which still are in process in the Mizar system, twenty years later, no further assassination attempts on House Libra were executed, but the actions of the past nearly turned the system into isolation from the other worlds, as former trade partners have been lost due to higher controlls at the system borders.
