No, I understand, and I'd rather avoid putting people at risk like that. But we obviously need to find something that can keep an unwanted god out of the complex. It is supposed to be safe, and there are children here.
I...would not know. While we had curiosities that could do that, I never tried to use them and see. But it was a defense mechanism that dated back over millenia, so it undoubtedly had it's roots in some sort of magic. I can try and isolate how that even worked, but who knows how long that would take when I'd have to build that technology from scratch and then deconstruct it again to figure it out.
