One night at Grimmauld place our one and only hero couldn't sleep. He sat at the kitchen table, looking down at his hands, all the while thinking about the prophecy that he was under.
"...and either must die at the hands of the other..." he murmured, narrowing his eyes. Just as he was about to continue with the thought, he heard the usual pop sound of apparition. He looked up towards the door to see Bill Weasley walking inside, his clothes slightly singed, and one eyebrow missing.
Bill looked up, and visibly brightened at seeing him. "Hey, Harry, how is it going?"
"...better than you, I think" Harry answered with a little humour.
"Erm, yes. There was a little mishap with the last tomb that we raided, and I couldn't make it out without some damage, as you can see." The older man chuckled. "Those wards are always nasty, even if they hold long forgotten treasures..."
He continued to explain, while making some hot chocolate, but Harry wasn't listening.
"...long forgotten things. Things that he wouldn't know about!" He said with a crazed look in his eyes. Maybe some sleep would be nice, but no. He was close to a breakthrough!
"What?" Asked Bill, not understanding his genius.
"You know that I have a prophecy, right?!"
"Erm, yes? Dumbledore told us about it?"
"Well, it says that only the Dark Lord can kill me, and vice versa.... that means, that I count as immortal to anything else!" He finished with a too wide smile.
"Bill, I need you to take me with you. I'll walk into the tombs, grab the things inside, and walk out. It'd be easy!"
"Harry, I'm not too sure about this..."
"I'll take a camera with me take take photos of the runes inside"
"Deal."
....
A week later, we can find our protagonist in a dense jungle. Before him, stood an ancient piramid. The air almost visibly rippled with power, as if the wards could feel the intruders already.
Harry took a deep breath, and started walking.
As he neared the wardline, he could feel some resistance, every step he took became harder, but he didn't stop.
As he stepped onto the wardline, it was almost as if the world held its breath. He could almost imagine it, two different powers, trying to force the other into submission. The wards on the inside, fate and prophecy on the outside.
He grinned.
There was a grinding-tinkling-whining sound, as if the wards couldn't believe it either.
And he stepped inside. Alive. Unharmed.
He turned around, and smiled at the gaping visage of Bill Weasley, with too many teeth to be called sane.
"I think... I think this is the beginning of a beautiful partnership, Bill."
...
A fun little prompt about a Harry Potter, who weaponizes the prophecy in a new way.
