The minute Draco stepped onto the Hogwarts grounds, he was drawn to the forbidden forest. He would wake up in strange places almost as if he was sleep walking, which had never been a problem before. When he gets sent to the forbidden forest with Harry, the pull becomes unbearable. When he has an excuse to break off from Harry, he bolts towards the source, and finds an ethreal plane. There he feels at home, so there he stays. He visits everyday late after classes, and stays until he has just enough time to get to his common room before curfew. He made it into his own little sanctuary, little did he know it was more than that.
