I am an inexperienced DM and currently about half way through "Shadow in the Sky", and have found the module difficult to run, simply due to the open endedness. I'm not used to having to pad so much, and have had difficulty keeping the party focused. Riddleport has so much potential for adventure, and i've tried to allow the PC's as much 'sandbox' time as they like, but they've pretty much stayed focused on doing Saul's missions, and keeping the GG running smoothly. The ideas in this thread are good and helpful, I just don't have access to Freeport, or a lot of other content to use to pad the story.
Any info, tips, resources, or advise to a novice DM would be appreciated. I considered starting a new thread on this topic, but there is so much info already flowing here.... ;)
