In Over Your Head

My, you are a bright one, aren't you?
I was once like you: full of untapped potential, brimming with desire for more power, and not an idea in my pretty little head of how to go about it. It’s only natural to push yourself to your limits and beyond. But first, you’ll want to know more about cultivating your relationship with Belial, Lord of Phlegethos.
The look on your face tells me you don’t fully comprehend what that means... Oh that’s rich! You’ve gone and accepted this power without first doing your research. Perhaps that should be your first task.
I happen to know that Councilman Aldwin Graves, in Helm's Hold, has recently done some research into your Patron’s kind. Seems like a good starting place. Enjoy the edification.
