I'm not a librarian, [he feels that should also be clarified?? He does office work, sir, and sometimes he organizes stuffed birds.] That said, I would... forbid you from entering the library, I suppose.

[Like, maybe he'd hire a bouncer, who knows. He certainly would not do whatever Kaeya is implying this librarian friend of his does, if only because 1) what the fuck, and 2) he simply cannot. Sad. 😔]

A sign could be hung behind a counter somewhere...

[Like they do for unwelcome rowdy drunks at taverns, specifically. Do Not Serve This Clown.]
