Prologue: A Dark Beginning

Lord Potter-Black, he was known. Master of Death. He had outlived his descendants, his emotions growing every darker, as the eternally young man lost every contact with humanity. He was amazingly good at faking normalcy, and had turned to knowledge as time had no constraints on him.

Magic was simple enough now, with a mere thought he could accomplish most spells and magical feats. Runes had long since become boring, and inventing spells for others to use when he needed none was too generous for his hardened heart.

He had delved into the blackest magic, blood sacrifice, rituals to enhance strength, memory, and many other things. He had grown bored of that, so turned to muggle science. He could, in time, achieve most any technological creation, and power it with magic.

When that grew boring he turned to genetics. His curiosity had him stealing gifts from others. He was an metamorphmagus now, he could use house elf magic, sing like a siren, and had beauty and appeal like a veela. He grew bored of that too. Now more creature than human, he had a delicate appearance and his long black hair was no longer standing up. His eyes were slitted and glowing green, and his ears were pointed. His canines were large, and his hands were clawed. He was dangerous, beautiful, deadly.

He had learned most artistic talents, because practice makes perfect and he had no end of time to practice in.

It was the year 2893. Technology had started tearing down magical shields, and the wizards and muggles were in a crippling war. He had no desire to save them, and there was nothing here he wanted or needed. His desire for something different had him creating a rune matrix, carved into obsidian, the entire floor in sharp pieces.

The Master of Death was ready. A confined unicorn lay on the alter, under a sleeping spell. Fawkes, a phoenix who had lived thousands of years and had become both his best friend and his worst enemy was bound by the leg with a rune carved band, tied to the alter.

Fawkes watched warily as the deadened man began the ritual, butchering the unicorn, that woke and shrieked a death cry. The silvery blood filled the runes and as the former Boy-Who-Lived chanted they lit up with a sickening purple glow.

Lord Potter had long since absorbed the Deathly Hallows, and he used that power over death to extinguish Fawkes. But one glowing phoenix tear of sympathy to Harry Potter's pain hit the runes before he disintegrated. And with a flair of brilliant light the rune matrix changed to a glowing gold.

The Master of Death could only watch as his body faded away, taking him into a new world. But what could one phoenix tear do to a world jumping ritual? That is yet to be seen.

A.N. I have no idea what I'm doing with this story. It just must happen. The only Master of Death crossovers I've ever seen had a Good!Harry… and I'm feeling a little Dark!Harry.
