Prologue: Death

Everyone has a soul mark. It is not inherently romantic, it just means someone fits you, completes you. Lord Voldemort grew up believing he did not have such a thing, that he was above common folk.
Then, one day, a prophecy happens. Someone who is his equal. And the Dark Lord would laugh at the very idea, but not a month later he finally earns a soulmark. Harry James Potter.

The war kind of goes downhill from there.
