Simply Complex

Harrison James Potter-Black saw two wars in his lifetime.

The first was as the Savior of the Wizarding World. The Chosen One of the Light. He fought the Dark Lord Voldemort, also known as Tom Marvolo Riddle.

The second was as the Traitor to the Light. The new Dark Lord. Protector of those with Dark Cores. He fought against the Light Side. Primarily the three he thought were his closest friends: Hermione Granger-Weasley, Ronald Weasley, and his ex-wife, Ginerva Weasley.

Loosing everything finally woke him up. That was when, using his powers as Master of Death, he went back in time.

Harrison James Potter-Black became Hadrian Antioch Peverell, a first year Slytherin in 1940, best friends with Orion Black, and a thorn in Albus Dumbledores side.

It was Simply Complex.
