The Necromancer grinned. He had waited years for this night, the night his slaves come home.
Aracniphobics were shifting through the woods, carrying the corpses he desired for his experiments.
His slaves, The Arachniphobic, were once children who lived in another dimension that could use horrific rituals to cross into other universes. The group of children were trouble making kids, always playing pranks on their town, but then one day, they killed all the livestock in the town accidentally, so on Halloween, while the group of kids were Trick or Treating, the town captured them and exiled them into our universe.
They found themselves in the woods, and came across The Necromancer, who tore off and burnt the children's faces, and made them his slaves, making them rob graves or steal children in the night. The Necromancer told them how to train spiders to capture their victims and hold them down. Then they found out that the only way to rest in peace is to find their faces again, so the Arachniphobic walk across the Earth, trying to find the double of them in this universe, so they can tear off their face and die in peace.
