His eyes slowly opened and he found himself in a very enclosed, wet and cold space, with a bruise on his head and scratches over his body. It seemed someone had brought him here very carelessly...but how? He looked around, something hard in the small space he had. He saw no exit, only hard brick walls and a narrow floor and ceiling. Where was he, and who had brought him here? He would soon find out...the hard way.
Meanwhile, in the deepest chasms of the Ministry of Magic, deep in the departments long locked away by the officials and ministers of the past, Neville was approaching the noble office of Lord Voldermort. He wore a dark purple robe and held the Sword of Griffindor in his hand. However, he had polished it with snake's oil and had covered it in vines, turning it into the more powerful but less moral Sword of Slytherin. He planned to use this newly created sword to destroy Voldermort so he could become the most powerful dark wizard, the true Dark Lord. And now he was closer then ever. With the Ministry in Death Eater hands, no one else involved in the war dared go there, but Neville's bravery and power was unmatchable, and now he approached the wooden door with the golden words OFFICE OF THE DARK LORD embroided on it as he walked down a dim corridor. He stopped walking, and reached out a bony, precise hand, then turned the knob.
He found himself faced with nine different wands pointing at his face.
"Ah." he said.
"I thought you would come here, Longbottom." Riddle snarled, cackling happily, walking towards him and lowering his hood to reveal Neville's angry face, and then beginning to pace across the room. "I am glad of this foresight. What a shame you will not be around to forsee my glorious victory." But Neville had just killed the nine death eaters with a flick of his demoncore wand, an ancient type forbidden by the current wandmakers due to it's unmatchable power.
"No matter." Voldermort said, almost managing a casual demeanor, after recovering. "I have the Elder Wand, and it cannot be beaten." Neville smiled, slipping the ancient weapon back inside his pocked. "Think again!" He said, and raised the Sword.
7 Months previously...
Fred and George sat together on the luxury chairs of the Hogwarts Express, looking out of the window to the beatiful view of fields that surrounded their school, Hogwarts. They were excited to finally complete their beatiful 7th year, and Fred found himself grinning widely. This was going to be a good year, he could tell.
"Would you like anything off my lovely cart, dears?" Asked the elderly Trolley Lady.
"Not now." Said George. "Just go away." Said George, surprising Fred, who eagerly set, "OH YES. I'm so hungry. Everything please!" And he threw lots and lots of money at the lady, who looked very cross.
"You goons!" She shouted.
"You miserable old lady!" Shouted George, all happiness evaporated. "What made you like this?"
She stopped. "Oh you want to know, do you? Well, sonnyjim, here is the truth!" And she raised her hand, revealing the elder wand. Her eyes flashed scarlett. "I AM LORD VOLDERMORT."
7 Months later...
Naevenrashta smiled, revealing yellow-tinged fangs, and bellowed, "THE DEMONS ARISE!" His words echoed throughout the world.
And, as Snape heard this words, away inside his small, enclosed space, he realized. Of course! When he had got knocked back in the alternate world! By getting knocked out, he had created an alternate future for that universe in which everything had gone terribly wrong, them discovering time travel, and now he was in the same situation but in a situation where they were now so evil in this new timeline, they were going to kill him! That had to be it. When he had died, the universe had tried to realign itself by shifting to where he had gone last when his soul had left the universe, but it no longer existed, so he ended up in this alternate-alternate timeline! Just as he realized this, water dripped down and formed a small growing puddle.
Molly took one look at the demon and promptly died...
