The Library of Certu stands in the northwestern tip of the Sallow, near its intersection with the Fringe, the Grey, and the Green. Its remoteness means that they only get about one visitor a day on average. The library is hidden among the fungal forests, but its observatory spire juts out from the mushroom tops, decidedly distinct with its non-pink color and appearance of carved stone blocks and wrought iron. A person from an entirely different world would call the architecture Victorian.
The door to the library has a sign beside it.

There's some sort of hole beside it that speaks the same five sentences at regular intervals.
