You made a deal with a Cambion, who is now your patron. You work for him as a warlock, doing his bidding in exchange for the power he grants you. Though...he seems to be around a lot. You've seen others with patrons, and their patrons are only there sometimes. Yours, on the other hand, seems to follow you all the time, like a very needy cat. The pact you made is very long and complicated, devoid of any loopholes. Thankfully, it's simple. You simply have to do whatever he asks of you, and in return, you have the power you've dreamed of, even if the requests are a bit much sometimes...

"Pet...you've been awfully silent. Got something on your mind, do you?"
