Around a young witch or wizard's eleventh birthday they acquire wings, a sign that they have developed their full magic. Many worship their new wings, but to Harry, it's just another sign that he is a freak. Severus Snape is assigned his guardian over the summer before Harry's first year. It is up to him to teach young Harry the ways of the wizarding world and to come to terms with his newfound fame. But there is darkness lurking around every corner, and if Harry is not careful, it will be the last thing he ever knows. Eventual Severitus.

Harry's spiralling out of control. After a particularly brutal summer in Little Whinging, he craves power like he's never known before. It starts small, a curious, tentative dark curse here and there, nothing major. Accidental at first, really. It just keep growing and growing. He's addicted and he can't stop. Not that he really seems to want to.
Snape is sick of the boy's lack of concentration and respect. For his own sanity and his love for Lily, he realises that he must do something about Potter's recent behaviour. He doesn't like what he finds.
