What does it mean to pierce the Veil, that which separates our world from the realm of dreams and demons? For the average man and woman, it is a frightening thought to consider just how fragile this separation actually is.
The Veil is not a physical curtain, not a structure limited to a particular place—it is everywhere. It is in their home, in the streets where they walk, in farmers' fields as well as remote mountain vales. At any moment it could be torn to shreds, allowing demons and other horrors to flood into our world like water through a burst dam.
Known lore tells us that small rifts can be sealed... but what about a large one? What if some catastrophic magical event created a rift so large and horrific, it weakened the integrity of the Veil as a whole? Such a "breach" would threaten our entire world, turning concerns about occasional demonic intrusion into a charming anecdote compared to the monsters we would then face.
If there is anything to be done, any reason we should look at magic with fear, it is for that possibility more than any other.
