The person is at Hogwarts, but the system is in Middle-earth!

While at Hogwarts, I awakened a Middle-earth survival system, but the system was acting strangely… [You received your Hogwarts acceptance letter—Main Quest: The Fellowship of the Ring!] [You didn't go to Gryffindor, but instead joined the Hufflepuffs, a bunch of gluttons—Reward: Hobbit racial talent (Stealth + Gluttony)!] [You refused Malfoy's handshake—Reward: Strength +1 (That's how you deal with fallen elves!)] [You wielded your wand powerfully—Reward: Two-handed sword strike (Magicians should have some strength)!] The system actually thought I was in Middle-earth from Lord of the Rings?! …Years later. Voldemort led his army of Death Eaters to attack Hogwarts. Before the Dark Lord could even finish reciting Avada Kedavra, Rowe Baggins, wielding Narsir, rushed in front of him and delivered a backhand frying pan strike. "Shut up, Sauron! You, without a physical body, are only fit to smell the ashes in my pot!" "Also, don't call me a wizard, call me the Sword Saint of Middle-earth."
