The consecrated grounds of Homura's residence had been silent for quite some time. Usually there would be at least some form of activity in the form of sacred rites being used to maintain the protective powers that surrounded the building, but it has been left dormant for some time.
Until now, wherein a sudden breach in the Immaterium somehow ripped through, even going past the defenses of the holy grounds - most likely because of negligence. Yet the one who arrived was Homura herself, forcefully ripping through reality to make a hastened return. The Grey Knight had returned after some time of being missing, and she was just finishing a battle with a Daemon of Nurgle.
The holy grounds acted like silver to a Vampire against the Daemon, causing its very being to burn away before its corruption could even take route in Real Space. Yet before the Daemon had a chance to return to the Warp where it may one day be reborn, Homura trapped the foul creature within a Tesseract Cube, sealing it in stasis and preventing its eventual reincarnation.
As quickly as the enclosed storm appeared it disappeared, with help of the warded grounds that patched up the tear in reality like nothing happened. The Grey Knight placed the Cube within her Time Shield, sending it to the pocketed dimension that also resided in the Warp to be stored hopefully indefinitely.
Yet Homura arrived as quickly as she could for the next campaign she would set herself. She had somehow found word of a previously befriended Madoka; being not only attacked and knocked unconscious, but split into several metaphysical pieces and stolen.
Homura was pissed. She would go out and both recover that which was dear to her, and bring vengeance to those that had wronged her.
"Ego sum malleo."
