Hello, Camelfox -
This sounds like a nice idea. For those who have a nice story idea, but can't put it coherently, I've got a handy little table:
Script/Story Outline Template
I. Set up!
Who, Looks & Personality 2.
What do the characters need/want? 3.
What do they think, say, or do? 4.
The End/Turning Point: 1.
Climactic Resolution 2
How is the problem/conflict solved? 3.
(It doesn’t have to end happily) 4.
Moral Message 5.
Hope this helps you to create another adventure.
