I expect it is hard to think seriously about tearing down a prison while you are still chained up inside it. You had to have your own freedom first, didn't you? It isn't - well, those monsters took you from your family. They must have wanted to destroy the magical bloodlines and any sense of kinship and duty you had to one another. I think that a man in a horrendous situation like that would do almost anything to escape, and I cannot fault him for it.
Is your friend here in Night Vale? Are the mages all free now?
