"It’s a secret library built by one of the Potters from my genealogical tree," he explained softly. "The secret was passed from one generation onto another, along with the key. The last time I visited was almost two decades ago and I don’t remember much, but the key was preserved in my family’s vault at the Gringotts. As far as I know, the place is a bit forgotten, not really maintained, but it’s not hexed or anything. You’ll just find a lot of dust and eerie silence."
