The problem with that... is whoever manifested this place in the first place dictates the rules about what we receive. When they're generous, we get a library that's bigger on the inside and has access to texts from many, many wordlines. But when it's not so generous, we get things like a knock-off costume shop-laundry facility.

If you're thinking "safe house", that's one thing, but you have to keep in mind the restrictions according to the "rules" this "world" follows.

[in fact, person who knows all about that kind of thing: this guy.]

You can try to find loopholes when you know what those rules are.
