Harry Potter: Hellgate

A/N: This came to me last night and I just needed to write it. Harry Potter: Arrow will still be my first priority.

A/N 2: I like the reviews.

According to legend, if the ravens leave the Tower of London, the world will collapse into rubble and humanity will burn in fire of hell.

They came from nowhere, it was at least what people thought. For science had taken over the man's faith, they believed only what they could define or create, ancient knowledge had been forgotten in the ancient time. Prophecies that had stood as warning for countless generations were seen as archaic folly or ignorant superstition, so when the times evil tried to begin to manifest, there were few who saw the signs and fewer who believed. And when the demons finally came, there was little that stood in their way.

They came from gates of hell and quickly and systematically overwhelmed humanity's defense. The nuclear and biological weapons that were used by a few desperate nations did little more than slow the apocalypse. No conventional weapons looked to do any harm to them and man fell, demons attacked everything in their path, they had no goals, they killed everything in their path, and only those with luck on their side, and the most well-adjusted survived.

But a group came out of the darkness, those who still practiced the sacred ancient knowledge from ancient days, they were the only thing that could stand against the dark invaders, they were a mixture of men from all the world's places, people who have sworn an oath to always stop the forces of darkness from winning. They consisted of people with weapons and spells, people who had been forged by their ancestral traditions and they called themselves Templar's Their success went up and down, the leaders of the last military forces on Earth could neither understand or accept their strange ways of life. But the Templar's continued to fight and they immediately drew attention from the more powerful creatures, those who seemingly before had been seen as immune to the weapons mankind used fell, but the man's last hope was too late. The demons became more and more and the Templar's began to lose men. They instead turned their focus from driving them back down through the gates of hell to try to save as many of their fellow-men as they could. They pulled back to the London Underground, an oasis and safe haven where they since the construction of the subway had in-built defense with special doors that could stop the demons from hell to get into.

The invasion, the unspeakable disaster that hit London gradually began to engulf the rest out humanity. The powerful nations that mankind has built up over centuries and millennia fell into ruins and demons of hell turned our world into theirs.

But the human race survived. Men and women were hiding in the shadows, they struggled to survive and desire to strike back at their conquerors was always there, and they stayed low to the time when their chance would come.
