In late 09.022M42 the situation in the Hadron Expanse was becoming critical. By this time, the Aleph Sector, cut in two by the Cicatrix Maledictum, had two very active warzones. In the Perseus Deeps the Imperium were locked in a titanic struggle with the forces of Chaos to control the strategically vital system of Mordecai. In the far east of the sector however, a new trouble was brewing for all the factions seeking to control the sector.
In 021M42 the Rifts of Hecate, an area of the Hadron Expanse that had been inaccessible for Millenia had become the focus of interest for the many factions of the sector, as the warp storms preventing navigation to the region had developed a navigable passage known as the Hecate Gap. This had been achieved by the machinations of the Lord Inquisitor Huron, who had discovered and activated the necron artefact known as the "Nexus Arrangement", which pushed the warp away from realspace using arcane and unfathomable technology.
The forces of the Imperium, Tau and chaos had sent expeditions into the region, seeking to exploit valuable resources or find long lost knowledge, but they had found the region less uninhabited than they would have preferred. In the Rifts, large ork, necron and tyranid forces had been discovered, and by late 09.022M42 it had become aparent that all three of these factions had become aware of, and intended to exploit the creation of the Hecate Gap. Lord Huron had not foreseen that by opening the Gap, he not only allowed a way in, but a way out.
Now the growing forces of the orks and tyranids in particular looked likely and capable of flooding through the gap and into the Hadron Expanse proper. From there they would threaten not only the Hadron Expanse, but the Zadoc subsector and then the Perseus Deeps. To counter this, Inquisitor Cyrus Esquerra, along with Lord Huron, issued an edict to imperial forces to pull back and fortify the gap while the Inquisition attempted to locate and gain control over all such Nexus Arrangements, as it had become apparent there was more than one such device hidden in the rifts. After obtaining them, the decision would then have to be made. Keep the Gap open? Or somehow close it, taking the Nexus Arrangements with them.
The Imperium however were not the only ones with an interest in this, and by this time all factions realised that the fate of the Hecate Gap, along with the course of events in the Hadron Expanse and perhaps wider, would come down to who held two critical systems. Ergura's Fall, and Haven. The focus of the rest of 022M42 would be a struggle to control these two isolated worlds.
This is a very simple campaign which will run to the end of the year. For each win each faction will get points they can allocate either to Ergura's Fall or Haven. At the end of the year any faction with more than 50% of all points allocated to a each world will control that world. If no faction controls 50%, the two largest factions will nominate a player for a "play off" game for control of the world. If two different factions control each world, there will be a final "play off" arranged for one faction to control both worlds. That faction will then decide the fate of the Hecate Gap (which will likely be to hold it open for Necrons, tyranids and orks, CLOSE IT, for eldar and for chaos/imperial/tau they will need to assess whether they want to take the risk of keeping it open and taking the fight into the rifts, or close it for relative safety but fewer strategic rewards)
Alliances: If you believe your faction has an end goal that is in line with your own faction's goal (e.g orks might believe tyranids will keep the gap open, which is good for them) you may gift your points to that faction. On your head be it if it doesn't pan out as desired.
