Last post I mentioned how I decided to complicate the Scourge of the Demon Wolf adventure. To do this, I decided to introduce a red herring, some bandits who were faking wolf attacks. To tie them into the situation, I added the body of a local tinker that they robbed and killed. Then the bandits made it to look like a wolf attack.
Then I asked myself would there be anybody else involved with the bandits? Having one of the Beggars clans in the area fencing the bandit's goods would be a good addition. To further tie this group in I decided that the Beggar Clan chief's son was killed by the Demon Wolf. Plus they have more information about the the mage's conclave than what the villagers know. From stuff I established in previous campaigns I also noted that the villagers would not be on friendly terms with the Beggar Clan adding another complication to the situation. That where I stopped, I learned that once you get up to four or five distinct aspects to a situation the players get confused.
Now I was ready to plant rumors about wolf attacks. The day of the game arrived and sure enough the players went down the road. They stopped at a crossroads inn and heard about the attacks and decided to investigate. It wasn't the only rumor they heard but it was the one closest in geography.
When faced with multiple interesting choices players are more apt to pick something that closer than further away. It not an absolute however. They could and will opt to pursue something further away if think that would be better for their immediate goal.
I don't remember much about that first adventure other than the fact they encountered every group involved. That they went from the summoning site to the conclave, talked to the mage at which point the final series of events started happening.
The thing to remember I did not write this in any amount of detail. I had two pages of note which you can download from here. And some paper character sheets with the NPCs and the Demon Wolf written up.
What filled in the details was my conception of what life in a medieval village was like, life in a bandit camp, etc, etc. This is part of what I call my bag of stuff. Nothing in there is as detailed as you find in a published work but I internalized it so I can pull stuff out of my memory and combine it with other stuff to create interesting situations for my players. Finally it has the virtue of being able to be done on the fly.
