God Himself built it, with me in mind, so yes--you could say that it was strong.

[ And the keys to it are here, in this world. Fortunately they don't actually work the way they're meant to. ]

This place is a little different. I mean, I suppose you could say it's a prison, but the Porter is just a thing. It would be a simple matter to destroy it, or reprogram it.

[ Hah. Simple. ]

But this place is more freedom than I've seen in centuries. It has its perks.
