I have to admit that I am genuinely impressed by the ingenuity of what you're describing here. I don't know much about magic, but I do understand engineering and programming and I know that making something with working parts such as these can't possibly be easy. It's genius work. And that it's a rework of something you did in school, it's more impressive skill.
That said, I also understand why you're asking me this privately. This is...
Very close to spying. It's potential to be invasive is strong, and you're clearly aware of it. It can be used as a weapon for someone creative enough to do so.
A few days ago, I would have really liked the ability to know if my kid was still here or not. It wouldn't have stopped me feeling horribly, but knowing would have maybe been better than not.
I guess what I'm trying to say is that I don't know. I'm not sure, and I know I should be better than that. I took charge of this place, and I need to have answers, and not just my own opinions that have to do only with myself.
