Hello! ^^
I'll try giving you an answer.
What are those modules for? what do they add to the main mod?
There are so many modules and options - it would take us hours to write everything down and to explain each module. So that's maybe the reason nobody has replied yet.
Buuut everything is clearly explained on Nraas website. If you click on the different modules it redirects you to the explanation and information about the specific module you've clicked. It takes some patience and time to read everything carefully, but it's fairly easy.
For example:
StoryProgression FAQ

http://nraas.wikispaces.com/StoryProgression+Interactionsdo i need Fairies And Werewolves module to add Supernatural criatures to main mod?
I'm afraid so, yes. You need the EP Supernatural. No Mod can give you supernatural creatures without having the right EP installed.
Will StoryProgression populate a whole new neighborhood? bacause i will install Sunset Valley 2013 and it's unpopulated
Twallan's StoryProgression Mod deactivates the EA storymode and replaces it with individual settings that you can decide. But using the StoryProgression can also totally crash your game if you don't read the instructions carefully. After installing StoryProgression and playing with it, you can
not simply remove it. So, if you wanna have it in your game then you really should read the infos on Nraas site carefully - and maybe look for some tutorials as well. That would be the best.
I hope I could help a little bit at least.
