Tiamat Hostilities

The was the opening salvo of an escalating proxy war conducted by the growing Confederacy of Former Covenant States against any non-aligned state or entity, with the aim of cementing their power on the Frontier. In an entirely one-sided conflict, the allied forces from the Jiralhanae Kingdoms, and the Union, steam rolled themselves through the rough alliance of human states called the Coalition Bloc. By the end of the campaign, the Bloc ceased to be, with every state either being conquered, seceded, or switched sides.

Background
The Frontier had a long history of being a difficult place to settle.Serving as a nexus between human space, and former Covenant territory, any attempts to settle it always met with resistance, usually in the form of slavers, pirates, and other raiders. In the past, aside from Covenant Remnant attacks, there was never any organised conflict, just random raids. In order to better secure themselves, several break away governments in the Frontier formed a single power Bloc, the Coalition Bloc, in order to have mutual defence and protection. For a time, that worked, allowing them to flourish and grow. However, the desire to keep themselves out of UNSC affairs distanced them from the larger, better equipped Frontier Coalition, a UNSC sponsored buffer state.

After Demiurge influence in the Jiralhanae and Kig-Yar civil wars, both factions saw one another as allies, and eager to curb human expansion. Overlord Marius had secretly provided arms and armaments to a number of Kingdoms of the periphery of his domain, with the objective to take these sectors. In exchange, they give a tithe of their haul. Likewise, Arku K'hban, a high ranking official in Dekd Nok's new Union, had egged on several pirate captains to offer out their services to the Jiralhanae, and used it as a means of bringing the state military in, with the intent of seizing several colonies he viewed as Kig-Yar owned.

Aftermath
The war was entirely one sided. The Jiralhanae and Kig-Yar forces, directly or indirectly sponsored by state forces, utterly steam rolled the Bloc. While attempts had been made during the mid stages to mount a counter-offensive, it was too late to prevent the end of the war. Ongoing resistance and guerilla conflict would cease by the close of the next year.

No less that 18 worlds were captured, being claimed by the captors in victory. The Navak Compact, Veles People's State, and Arrandale Free Traders having changed sides during the war, to varying degrees of success. The Returik Trader Coalition suffered a coup d'etat and the new ruling party aligned themselves with the invading Kig-Yar forces. Of the remaining worlds, only the Hibernia United Colonies remained free at the war's end, by leaving the Bloc and joining the larger Frontier Coalition, although this was more a stay of execution, since they would be conquered during the War of the Confederacy.

With the Bloc gone the Confederacy came closer to controlling the Frontier. Major space links between Jiralhanae and Kig-Yar space were seized, and forward staging areas established for attacks further afield. These worlds would, in time, service the war machine of the Confederacy, helping them conquer further colonies.
