At 1st level, you have struck a bargain with an otherworldly being of your choice, such as The Fiend. Your choice grants you features at 1st level and again at 6th, 10th, and 14th level.

Pretty much says ride the lightning.
Ehh, I've seen plenty of players mess around with that. I know a player who's warlock didn't make a deal. Instead they quietly steal the power from their patron. If he gets caught, he's toast, but it is an interesting way to flavor it.
