After deciding on doing a small module design document I started looking for samples that other module creators have used. I did searches on NWVault and the NWN2 forums. I also posted a message on the NWN2 forums to get some feedback from the community on the need or use of one.
I have looked at a few design documents and have decided to use the one from Solvheil as my base. Thanks to Solvheil team for making this available. Here is a link to there development blog if interested.
Because I am recreating a PnP module most of the detail design work has been done for me. So I just needed to add in the Companions, Starting details and details on the village of Silverton. I am about 60% done with the design document depending on how much detail I want to go on quests, companions and such.
I made some great progress on the custom OnDeath script. I have everything just about working right and should have it 100% done in the next few days.
You can download my design document from NWVault link provided below. *Just to warn you there are spoilers in the design document.
