Making things up. These forums are the only reason I know the names of any purchasable adventures. I'm sure there are some good ones, but I didn't come up with them, so they'd just make me spiteful. And the ones that aren't good, I don't want those. It's a lose-lose situation. I'm groovy without book adventures anyway. I still plan the campaign, and try to break it down into little adventurey bits, and I come up with locations and characters in any important locations. Otherwise, if someone is interested in something, maybe I'll make up a story about it. Now, if I've got an idea that I really dig at the time that I want to incorporate into a sidequest, there will be some way to throw it in. That is, if I was contemplating using a group of renegade deathless monsters to confuse the cleric and paladin (since positive energy heals them, and good clerics rebuke or command them), and someone in the party decides they want to do something worthy of a sidequest, they'll run into these renegade deathless somewhere along the way.
