Original Neverwinter Nights Campaign Document

RPGWatch is pointing to what appears to be an early design document for Neverwinter Nights' official campaign. There's no way to know if it's real or not, but it's obvius that someone put a lot of work into it. How about this conclusion?
In Forgotten Realms lore, the Creator Races (of whom Morag's Old Ones were a part) had the power to create entire worlds. The Sourcestone lay at the heart of that magic and it was what made such feats possible. It stands as a symbolic representation of our toolset and of the worlds that our players will experience beyond the confines of our campaign.

The party's shadow members, if victorious, can be seen as having embraced the death represented by the fourth environment. They have found the greatest evil and it is within themselves. Having purged their party of any remaining elements of good and turned on Morag, their Mistress, they now usurp the power of the Sourcestone for themselves. Haedraline is no longer Morag's Wordslave but their own. They have become Lords of the Shadow World, Lords of the Dead. They are Kings over all they survey and, more importantly, over all the Sourcestone allows them to create.

The true party members, if victorious, are rewarded with a symbolic resurrection from the death represented by the fourth environment. Using the knowledge of the dead, they have purged the shadow elements from their party and, in preventing Morag's Awakening, have freed both Haedraline and Neverwinter from the clutches of the '˜shadow world.' Unable to free themselves, however, they must recognize that, in becoming a Hero, they have also become a Monster. Having rejected the '˜shadow world,' it is still a part of who they are and they bear its mark upon their hearts. There is no place for them in an '˜ordinary world' that counts them among its dead. No longer a Wordslave, Haedraline offers the Sourcestone's power to the players that they might create for themselves a '˜new world' into which they can be reborn.
