<Hell . . . I don’t know how to put this. The scrivers figured out a way to combine sigils to make a bunch of new languages. Ones that are more specific, more powerful – ones that can convince items to be really, really different. So they can make locks that only open for one key in the whole world, and they’re completely unpickable. It’s not a matter of pressing and pulling on the right lever, or something – the lock knows there’s only one key it’s supposed to open for.>
