Heres an idea then:

On the western border of Vigilius sector was the planet Volharian which the Mechanicus claimed becouse of it's vast mineral resources. However, due to the planets extreme teutonic activity, turning it into a forge world would have been impossible and so they converted the moon instead. While converting the moon, the Mechanicus forces stumble upon ancient technology dating back to the Dark Age of Technology. Elated, they message the greater Mechanicus about their discovery before all contact ceases. After 5 years of silence the other Mechanicus forces grow concerned and investigate. To their horror, they find that the Mechanicus have fallen to the corrupting powers of Chaos due to the corrupted nature of the recovered technology. In the five year time period of silence, Volharian's moon has started the process of becoming a Hell-Forge.

When they arrive the Heretic Mechanicus are building machines whose designs were drawn from the corrupted Archeo-tech and putting the machines into orbit around the solar system's celestial bodies. Seeing themselves outnumbered, the loyal Mechanicus forces attempt to retreat in order to call for reinforcements and the heretic forces try to stop them. Despite outnumbering the loyalist forces, two Mechanicus ships manage to make it to the system's Mandiville point and make the jump to warp. Knowing they will bring too many Imperial reinforcements for the heretic forces to match the Heretic Arch-magos decideds to activate the devices early, creating a warpstorm. However due to the early usage, before all were made and in place, the warp storm merely engulfed the system and not the whole sector as they had hoped.

Now, nearly 4 millennia later, the warp storm still rages, growing and shrinking over time between 150 and 200 AU. The Imperium suspects that within the warp storm, the machines still exist, causing the warp storm to continue. However, every attempt to invade the warp storm has ended in faliure as even the geller fields of Imperial vessels could not continue to function within the storm. For millennia it has raged and the long silence from it has led the Imperium to believe the Heretics perished when it first activated. But now, when more threats assail the Imperium than ever before, the storm has begun to roil with activity as heretics see their oppertunity arise.
