There are over 3000 Faces spread over the entire continent. I can't imagine just four Dragons getting them all.

Though it does make me wonder what Face really is. It was called a pulse bomb before, which would indicate that it explodes and wipes out magic.

But if destroying them helps, does that mean they are actually magic blockers that need to keep running to suppress magic and that magic will return the moment they are destroyed or deactivated?

I hope this will be made a bit clearer in the next few chapters.
