Wrath of The Lamb

Severus Snape wasn't always a grumpy professor with a permanent scowl and a brooding presence. He was once "Sev". He was the Half-Blood Prince. He was a Death Eater. He was all of these things before he became the man we know from the canon. Each phase of his life had its own place, causes and consequences, and they all coexisted to create one of the most complex and discussed characters in the whole saga. This fic aims to understand exactly how Severus Snape became Severus Snape. From the age of fifteen until that fateful Halloween night.

...or Severus Snape's slow descent into madness and involvement with a dark cult of wizarding terrorists.
