At the heart of the Tinea Swamp, where the trees grow thick and tall, lies a secret hub central to Vespera's teaching. Staircases crafted from the trunks of the trees themselves wind high up into the canopy, where the branches twine together thickly to form solid floors and walls. Dozens of the most ancient of swamp trees form dozens more rooms, the wood worn smooth from the many horses that have come before. It is here that Terrastella's hospital is concealed, protected fiercely by both the swamp's natural defenses and Vespera's people.
