When Lilith Mother of all Demons was freed from Leviathan, her mystical prison, and summoned her Lilin, their presence weakened the dimensional fabrics and this led to a reality rip to occur in Phoenix, Arizona, in a rundown building basement. This rip allowed a hive-minded bacteria known as the Viral Swarm to enter Earth-616. In the Viral Swarm's home world, they were the dominant life-form as they had fed on and consumed all other living beings. The Viral Swarm, seeing the reality rip into Earth-616, saw this as an opportunity for new life energy to feed on.
The basement in Phoenix, Arizona was being used by several homeless people as a shelter. The Viral Swarm bacteria separated and in doing so found amongst the various homeless people individual hosts. This particular part of the hive bacteria would be the only one that did not pick a homeless person that was inside the basement. It was instead drawn to a bitter and angry woman named Maggie who was just outside the building. This aspect named itself Macabre and became the leader of the group.
