What is the quickest way to get a Dark Wizard?

I have not completed the main quest, but would like to start going through free play to start working toward my 100%. What is the earliest point in the story I need to be and how do I get my first Dark Wizard?

Best Answer

The first dark wizard I unlocked was Snape. He is in a secret area off of the potions area, taken from this guide:

You will unlock Profressor Snape once you have access to the Secret Area in the Potions room. To access this room you will need a Hufflepuff character, a book carrying character, and a character with a key. His icon is located in a chest in the Secret Area.
