Harry Potter and Shadow of Mordor/War crossover
Harry, who had been forced by his 'loving family' to clean out the attic of number 4 Privet Drive in the dead of summer, decided to take a break and open a small wooden chest that looked like it didn't belong to his relatives. Inside was one thing, and one thing only. A beautiful platinum ring.
He felt like he could hear the whisper of voices, but looking around her found himself still alone in the sweat-inducing attic. Shaking his head, passing it off as his imagination, he picks up the ring in his right hand. Oddly enough, the ring is almost ice cold to the touch, and starts to glow an ethereal blue. Something within him tells him to put it on his finger, like he'd never wanted to do something more desperately in his life.
After sliding the ring onto the index finger of his left hand, the much-too-large ring sizes down to fit his child sized finger. He feels a wonderful rush of power, which also happens to cool him off, as he was still sweating profusely.
"So.. someone finally found my ring. " A deep male voice resonates within his mind.
"I must be going mad from the heat if I keep hearing voices." Harry murmurs to himself.
"You aren't going mad." The voice states irritably. "The ring you're wearing holds my life force, and lets me communicate with you, as well as a large host of other abilities that we will get into at a later time. My name is Celebrimbor. So tell me, boy... What year is it?"
Harry / Fleur pairing
Apologies for any bad grammar, it is completely up to you how he finds the ring or how the conversation goes from there. I've been playing Shadow of War again and had this pop into my head.
