Something Wicked Comes This Way (смешанная)

Whoever fights monsters should see to it that in the process he does not become a monster. -Friedrich Nietzsche.
After defeating Voldemort and leading the war against muggles years later, the Immortal Master of Death, Harry Potter has grown apathetic to everything. Yet he still dreams of obsidian eyes and a permanent sneer. So when given a chance to live out his life again from the start in another dimension, not as the-boy-who-lives, he takes it.
Harry plans to live a life of peace with Severus Snape as his new guardian but things turn awry as dark lord and death eaters come creeping up to destroy it. They all better remember that monsters never leave, they only sleep, ready to be awoken.
