I am trying to make a list of wikis for the various NWN games and modules. (I had to create one myself too cause it didn't exist)
If you know of any I missed (or decide to create one for a premium module / a community module that doesn't have one yet) then please post a link here and I will edit it into the first post.

Core Games:
NWN1: http://nwn.wikia.com
NWN2: http://nwn2.wikia.com

Premium Modules:
Wyvern Crown of Cormyr: http://nwn-wcoc.wikia.com

Community made campaigns:
?

I honestly feel that there is no need to create seperate wikis for all the premium modules, as they could be covered in the Neverwinter Nights wiki. Though do as you place, it's not my place to judge what deserves a wiki or not.

Considering each one is as long as some full length games and has dozens of quests and locations and the like it would be a right bloody mess to put them all into a single wiki
