A coalition formed to fend off the extra-dimensional invaders. They are known only as the Breach Invaders. The founding members of the coalition are the Dominion Peace Corp and the Hesukar Directorate. The Breach Defense Cooperative is a junior member of the coalition. They were included because of their efforts to suppress the single breach manifesting outside of Directorate space. As a community made up of class two and class three civilizations, they should not have been able to withstand the invading forces. Dominion intelligence suggests that the Breach Defense Cooperative is only able to suppress the breach for this long due to the intervention of a higher-order entity. The associated members are a part of the coalition in name only. Their contributions to the war efforts are minimal. Dominion insistence to include them stems from their desire to stop them from abandoning the armistice achieved in the Karkish-Adranarian War.
The coalition forces are primarily made up of Dominion (65%) and Directorate (32%) vessels. All remaining vessels are either part of the Breach Defense Cooperative (2.9%) or run by independent captains. In terms of military strength, the Dominion vessels outshine the other coalition members even more (~85%). The biggest space ship is the Dominion Super-Class Carrier Ashendon. The key to successfully closing the breach is the destruction of the infrastructure keeping it open on the other side. With conventional means, this is nearly impossible. However, the Dominion can deploy nova bombs capable of destroying entire solar systems. The Dominion uses disposable drone ships to deploy the nova bombs safely.
The coalition was formed after Dominion long-range scanners confirmed the existence of more than a dozen breaches within Directorate space. In accordance with Dominion protocol, they entered into negotiations to ensure that they would not have to fight a two-front war after entering their space. After years of isolation and confidence in their ability to continue the suppression of the breaches, they were reluctant to enter this coalition with the Dominion. This changed the moment the Directorate Hierarchy confirmed that Dominion had indeed quickly and easily closed the breach outside of their territory. After short deliberations, the coalition was formed and the Dominion forces were allowed to enter Directorate space. Once the Dominion forces began the operation to close the breaches they were able to quickly end the conflict.
The coalition was disbanded only 3 GSY after its founding. It was replaced by a series of smaller treaties between the various coalition members. The most important of which is the non-aggression pact between the Directorate and Dominion forces. The Breach Defence Cooperative began a major restructuring of their association under the guidance of the Dominion which ended in the formation of the Nesklar Federation.
