This press release from BioWare announces plans to open an online retail outlet at store.bioware.com on November 10. The store's initial inventory will be three bits of premium NWN content:

Neverwinter Nights: Kingmaker (Developed by BioWare designers Cori May and Dan Whiteside):
Embark on a journey that transcends the bounds of life and death with a loyal band of companions at your side. Evil lurks in a war-torn keep, and the souls of trusted companions must be sacrificed to unearth it. To uncover the truth, you must win the throne.

Neverwinter Nights: ShadowGuard (Developed by Ben “Altaris” McJunkin, developer of “Lone Wolf” series of Neverwinter Nights fan modules):
Your astonishing work at the Imperial Academy has drawn the attention of the Shadowguard, an elite group of secretive Imperial agents that know no failure. Your veil of comfort will soon be torn away and you will be left to solve the mystery of what lies ahead.

Neverwinter Nights: Witch’s Wake 1 (Developed by BioWare designer Rob Bartel):
Recently remastered to bring it up-to-date with the latest new content, this new edition of the classic Hall of Fame module lays the official groundwork for the series. In the module's opening scene, you awake on a raging battlefield to bear witness to your prince's dying words: "Tell the king that she is dead." Those seven fateful words mark the start of a journey that will propel you from the edge of a dying world into its very heart.
