I really like this idea. Thank you for puckona this up!.I think the free form nature is great. I think the presentation could use work.
As a DM it would be much more helpful to have some flow charts of key information along with 3 or 4 suggestions for how to implement the various aspects of the story. I don't want step by step directions because my players are going to go nuts and do things all crazy anyway. But a zoomed out view that gives me a quick and easy to understand map of the entire stories elements across a 2 page spread is much easier than reading a 200 page book and taking notes.
This sounds like a good idea. Since I'm currently structuring a similar (but hopefully different) campaign challenge for the Aslene expansion, I think I'll pick up on this and make a flow-chart suggesting how players MIGHT have pieces of information presented. The information may obviously be presented otherwise, but this would give the SL a structure to consider, as well as an overview of the different pieces.
On a side note, for our international friends: ”SL” is swedish for ”GM”...
