10. Sentinel Gap Walls of granite soar on either side of the narrow canyon floor. A chilly breeze whistles and tumbles between the cliffs.
and some of the areas have more detail. The above is enough for me to get a sense of the place as the PCs visit it.
I actually liked that there were ways to get the PCs to one of the Expositors of Plot (the Pegasi will take them to the Forestmaster no matter what they want if they capture them and fly them, the Centaurs will carry them there) because the PCs would be free to NOT capture the Pegasi and, of course, they don't HAVE to go into the forest at all if they choose not to. There just enough detail in the "throwaway areas" that I could probably build adventures in every one of those locales (and might have to, since this is a true old school product with Random Encounter tables). I'm looking at DL1 as my model for hex filling - for rounding out a wilderness area with general descriptions and letting random tables to their thing for the details.
Yes, the plot following got way too heavy handed (really, if a NPC gets killed and he is needed later...you really use the soap opera convention on him? Really?) and the need to follow these particular characters was annoying... But it started off so promising.
So, don't buy any of the rest of the line. But DL1 is, for me, a nearly perfect AD&D adventure.***
