Midnight Journey Home from Hogwarts

Wren Prince is the adopted son of Severus Snape. He has the blood of the Prince family in his body, and he is extremely talented in potions. He also inherited his adoptive father's unforgiving and poisonous tongue. But his talent brings a curse: his soul anchor is inherently unstable and is easily disturbed by powerful magic fields at night. If you spend the night at Hogwarts, it could trigger a magical riot at best, or cause your soul to leave your body at worst. Therefore, he became the only day student at Hogwarts. In 1991, Wren entered school the same year as Harry Potter. Each night, while other students gathered around the fire in the common room, he walked alone across the moonlit lawn toward the black-robed man waiting in the shadows.
