Emily and Jack stood in front of the old library, the key in Emily's hand trembling with anticipation as she inserted it into the lock. With a click, the door creaked open, revealing a dark and musty room. Emily hesitated for a moment before stepping inside, Jack following close behind.

The room was filled with shelves stacked high with dusty books, and in the far corner, there was a small table with a letter and a map lying on it. Emily made her way over to the table and picked up the letter, her heart racing with excitement and nervousness.
