AU. Voldemort kills Dumbledore but is defeated by a child. In the aftermath, Snape becomes the Headmaster and radically changes Hogwarts. Harry Potter of House Slytherin begins his Third Year at Hogwarts Battle School and realizes that friend and foe are too similar for his liking. Competing with allies and enemies, Harry finds there is a cost to winning.

Some men live their whole lives at peace and are content. Others are born with an unquenchable fire and change the world forever. Inspired by the rise of Napoleon, Augustus, Nobunaga, and T'sao T'sao. Very AU.

Why is Harry Potter considered the worst firebender in Gryffindor? Why doesn't he want to be noticed? Probably the same reason he dreams of drowning every night. [Harry Potter characters in an AU with magic replaced by the elemental powers of Avatar: The Last Airbender / Legend of Korra. Full summary inside.]

1000 years in the future Earth is no longer habitable. Humanity now lives on board large dome ships in Earth's orbit. However the Grail Wars have not stopped. New Masters, New Servants, New challenges. A new kind of War has evolved.

COMPLETE. Firefly: :Harry Potter crossover Post Serenity. Two years have passed since the secret of the planet Miranda got broadcast across the whole 'verse in 2518. The crew of Serenity finally hires a new pilot, but he's a bit peculiar.
