The trees are oldest in the northern reaches of the Viride, reaching far into the sky. Those who wander so far may begin to notice the forest changing: overhead their branches interlock tightly together, a canopy that keeps out the weather and, often, the sunlight. The trees grow closer together, their trunks widening into walls that create many hallways, and many rooms. And carved from these wall-like trunks are shelves; hundreds of niches where books and scrolls rest. Every few meters, a lantern is hung directly on a low-lying branch, providing ambient light for reading and studying, and many equines have left blankets and pillows to rest upon. Often it's the most sagely of characters who seek out the Library, but most everyone can find themselves awestruck by the whispering of the trees.
