The CEP is a combination of pretty much all the best hakpaks ever created by the community combined into one easy to use hakpak. You have to edit the campaigns yourself to input the CEP for use in them. Its basically turning your campaigns into modules, then opening them up and putting in the CEP in the Aurora toolset, then saving and converting it back to the campaign. It takes awhile. I found it on the main NWN forums.
One of my advisors will be an average five-year-old child. Any flaws in my plan that he is able to spot will be corrected before implementation.
