The only way to breach the Veil and get into the physical Fade is to use magic that requires more blood to power than probably exists in the mountain. The magical anchor on my hand is the only thing that can open rifts to get in. None of the mages here are inclined to figure out how to do it otherwise, let alone having the power or the skill in the first place. I would have the only key, and it can't be stolen or gifted or used without my permission.
