Sigma Triumvirate

The Sigma Triumvirate was the original name of the intergalactic peace-keeping organization before it became the Sigma Republic. It began early in recorded history, dating as far back as the arrival of the ancient alien race known as the Wraiths who guided various civilizations into becoming a cosmic coalition. Their job was to monitor their affiliated galaxies to ensure no conflict ever came to threaten the universe. But many had felt they were losing their freedom once the Nova Corp was formed, which served as an active police force sent to participate in each system's affairs to prevent conflict. After much heated discussion in a failed attempt at ironing out solutions to the matter, the Triumvirate was split with one side believing the universe should be reorganized for peace while the other wanted to let their systems choose for themselves. This led to Bardoss III, the leader of the Nova Corp, storming out to begin his campaign against every world he felt were a threat to the society he envisioned, which would go on to become known as the Bardoss War.

While the Nova Corp started with good intentions, their ideology grew twisted as several systems they targeted actively fought against them. It wasn't until the discovery of a mysterious alien product dubbed "Nightmare Matter" that they became the very threat they sought to destroy, with Bardoss fancying himself an Overlord and creating horrific creatures. During all this, the Triumvirate made more allies with worlds against their splintered group and held their enemies back long enough for the fabled League of Mages to arrive and explain what Nightmare Matter was. This group formed long before the universe's foundation revealed that the substance was an unpurified remnant of an expired universe that when left unchecked could lead to extremely negative side effects for anyone or anything that came into contact with it. The League were on their way to make the repairs as intended, but by the time they arrived, Bardoss had transformed him and his forces into something more vile, culminating in the final stages of the war where the entire universe needed to band together to stop his plan once and for all. Together with the Brutes and Thexians, the Sigma Triumvirate fought tooth and nail to put an end to the fallen sub-faction they created, ending with Overlord Bardoss' demise and the defeat of his army across the universe.

With the war over, certain systems like the core worlds of Thex and Aura Prime would cut ties with the Sigma Triumvirate since their partnership was largely out of obligation to stop the Nova Corp; not because they liked them. Many affiliates during the war felt the Triumvirate were to blame for Bardoss' betrayal, which led to the faction being rebranded and restaffed into the Sigma Republic.

Nova Corp
As mentioned above, the Nova Corp was the police force created by the Triumvirate to monitor and engage in the activities of the universe to maintain peace. But their method of doing so led to the systems they protected to feel that their freedom was being stripped away. The group's leader, Bardoss III, strongly felt this was a necessary sacrifice to keep everyone safe. However, the very organization that greenlit the sub-faction began to emphasize with the worlds that were rooting against them. This led to a disagreement that culminated in the Bardoss War. And while their intentions started out pure, they quickly became more corrupt for a multitude of circumstances; the worst of which took the form of NM-23/Nightmare Matter which worsened their ideology. This is what forced the ST (with help from various affiliates) to total the very army they created, slaying Bardoss and his monsters.

Thexian Warbound
Thex became one of the key targets of the Nova Corp, and by extension the Sigma Triumvirate, early on in the organization's run after the anthros of the world overthrew humanity following many decades of abuse. By then, King Chance II was in charge and was approached by members of the Triumvirate over a partnership ensuring his planet's protection while also having the chance (no pun intended) at advancing their technology thanks to other affiliates like the Mechas. Chance at first refused after reviewing their terms more closely and seeing the bias towards his kind that the Nova Corp shared. But while processing his decision, the Bardoss War began and he knew immediately that the group he was bitter about would come after him and his people. With this, he annexed Thex with the Triumvirate, but only under contract to keep the group from meddling with his kingdom once the war was over. During it, however, the King made great relations with the Mechas and Aurans and formed a non-verbal partnership of their own which kept them in each other's good graces even after the war (to the point where its common for Aurans and Mechas to live on Thex). By the time the conflict came to an end, Thex was declared an independent nation away from Republic jurisdiction.
