The library was quiet except for the soft scratching of quills and the occasional rustle of parchment. Oliver Wood was hunched over a large, leather-bound notebook, quill in hand, meticulously drafting a new strategy for Gryffindor’s upcoming Quidditch match. Diagrams of formations and player positions sprawled across the pages, every line carefully considered.

He had just finished plotting a daring new maneuver when the sound of rapid footsteps echoed through the stacks.

“Oliver! Oliver, you’ve got to see this!” Harry burst into the library, eyes wide with panic.

Oliver looked up, eyebrows raised. “Harry? Calm down. What’s going on?”

Harry stopped in front of him, nearly out of breath. “I… I messed up. A spell went wrong. I didn’t mean to, I swear!”

Oliver blinked, leaning back in his chair. “You what?”

Harry ran a hand through his hair, voice rising. “It was supposed to be a small dimensional observational charm, nothing major, but… something happened, and now… there’s someone here. A person. From another reality.”

Oliver’s eyebrows shot up. “A… a person? From another… what?”

Harry’s hands flew as he tried to explain. “I was practicing a translocation spell, okay? And I think I accidentally… brought someone here. From somewhere else. And she’s in my dorm right now.”

Harry exhaled shakily, trying to describe her. “She’s… tough. Lean, athletic build. Dark hair, cut short, a little messy, like she doesn’t even care about it. Eyes sharp, fierce, piercing—you know that look that makes you think she’s always three steps ahead? She looks like… like someone you wouldn’t want to mess with, but also… like someone you could trust to have your back in a fight.”

Oliver’s mouth opened slightly, the image forming in his mind. “Wait… a sword?”

Harry nodded frantically. “Yes! And she’s… she’s standing in my dorm, waiting, looking… confused. Totally confused. I told her to stay put, but I don’t know how long she’ll actually obey.”

Harry nodded, biting his lip. “I… I don’t know. I just… thought you’d need to know. You’re… good at this kind of thing. Calm under pressure. You can help me, Oliver.”

He grabbed his cloak and quill, stuffing the notebook under his arm. “Alright. Let’s go see this… this girl. Harry. I swear to Merlin you should be banned from using magic sometimes"
