The Paper Trail was not an ordinary bookstore.
And neither was the owner.
Leila did not know exactly the type of creature the old uncle was, but she knew he could not be an ordinary human. She suspected he was either a cultivator or a warlock, but she never saw him display any powers.
In addition, she did not know his name. Some people called him the Bookkeeper, but she never heard an actual name. She called him old uncle because he mocked her the first time she entered the store.
At the time, she was about fifteen or sixteen years old and stumbled to the store after a long night of fighting in the Colosseum District. She entered the store in her fox mask which she used during fights. It was not an uncommon practice for people to wear masks in Ghost City. An open identity could attract danger.
