The Utgard Infestation

The Utgard Infestation was a narrative campaign fought between the Genestealer Cult and Tyranids (controlled by Matt) and the Sisters of Battle and Inquisition (controlled by Leland).

Synopsis
The Hive World of Utgard is a minor industrial world who supplies ammunition to the local Imperial Guard regiment, as well as their regular soldiers. It's populated by billions of humans.

This planet is very important to the Adepta Sororitas because there is a convent on this world led by Canoness Commander Selenne. They operate close to the Hive City of Scar where they are the guardians of a Shrine with a relic in it.

On Utgard, they encounter a few political difficulties which cause troubles in the Hive City. The local authorities try to find out what is going on and discover that there is a cult. They believe that this is a Chaos cult and they send forces into the underbelly of the Hive City to take the cultists out. But they fail and get pushed back every time. The Governor asks the Sisters of Battle for help. Canoness Selenne is happy to destroy some heresy.
