A wizard should talk about his warlock friend like this: "That guy? He's a warlock. In my pursuit of knowledge, I myself have often felt the temptation to go to the dark side, to delve into those secrets and to commune with those beings that the gods tried to keep locked away - and for good reason. Many who gain such insights go mad. But a true warlock is one who is strong enough of mind and soul to not only unlock such forbidden insights, but to master them. He is cunning enough to bargain with arch devils and arch fey and come out ahead. He is willing to do almost anything for power, no matter the perils. It is fair to say that I regard him with wary respect, and even a healthy dose of fear."
