Question about NWN

[Semigall]

Does CEP and PRC packs add their content to the main game/main single player campaign or is their content only for user created campaigns/scenarios ?

As far as I know they would not alter the actual Neverwinter Nights Campaign in any way. However, if you play through a module with a character and collect some loot item found only in one of those packs, it can carry over into the main campaign.
