A/N: So this is a Warframe & Harry Potter crossover, haven't seen it done before. If you haven't played Warframe or Harry Potter you can look stuff up on the respective wikis. This is a small prologue because I didn't quite feel like making a longer one.
WARNING: Spoilers for both Warframe and Harry Potter
Harry Potter and the War Within
PROLOGUE (alternately: In Which Harry Makes A Rather Sirius Mistake)
It was as if the world had paused for that vital moment. The jet of red light had sailed under Sirius' arm, and hit him in the chest. The man had just enough time to make eye contact with Harry before he was blasted into the Veil.
"SIRIUS!" shouted Harry frantically as he ran towards the archway. In another world, another time, the strong arms that reached for him would have grabbed him, held him back, told him Sirius was gone - but this was not that world. Harry dove into the Veil, thinking only of his Godfather, and not of the six friends he was leaving behind.
Remus collapsed onto his knees, battle still raging around him. His fellow marauder, and his best friend's son, both lost in a matter of seconds. He knew where that archway lead. It wasn't called the Veil of Death for nothing after all.
"No..."
Harry didn't know how long he'd fallen, in this strange grey darkness. The whispers that had tantalized him before now spoke truths he could not comprehend into his unwilling ears. He felt a strange power, a presence, that went inside him, became him. It was maddening, and yet Harry held on. Eventually, the whispers reached a crescendo, roaring ancient words, searing strange instincts into his mind. He understood everything, yet nothing. And then - silence.
No, the presence was still there, but the whispers had gone silent. Harry was startled to notice that he wasn't falling anymore
He was lying facedown on a cold, metal floor. He looked up to see a crowd of small children huddled in a corner, looking at him. He sat up.
"Hello." he said tentatively. "Where am I?"
They just stared at him with wide eyes.
Harry looked around. "Where are all the adults?"
One boy, about eleven years old, stepped forwards. "They're all acting strange, mister. We're hiding from them."
"Strange? In what way?"
The boy swallowed. "They don't remember us. All they do is hurt each other." He took a breath and glared at Harry defiantly. "You can't make us go back to them. They got to keep us because they were family, but now they're not. The only family we have now is each other."
Harry looked between him and the group huddled against the wall a few times, before nodding. "Adults are weird, anyway. So, my name is Harry Potter. What are all of yours?"
A/N: And that's how Harry entered the Void.
