The Library of the Song of Truth is a dilapidated building that houses a book called The Song of Truth. Unfortunately all of its pages are blank because the words are locked behind a very powerful seal. This seal also protects the book from all altercations including ones that would damage it, which is why its in perfect condition. Most of the other books and scrolls here are in poor condition due to being exposed to the elements, only some of the furniture is still intact but are occupied by lizards.
The place is full of plants reclaiming their territory over the library, things like flowers, moss, and ivy to name a few. There's a section dedicated to the plants Brespawn grows here.
