its the rumored to be the final premium add-on module to nwn1 to quote gamebanshee
"Wyvern Crown of Cormyr is likely to be the final premium module for Neverwinter Nights. (Originally, Infinite Dungeons was supposed to be the last module, but then BioWare decided to release Wyvern Crown of Cormyr as well, and so I suppose it’s possible that another module might sneak in under the gun as well.) That makes six premium modules in total, and, by all accounts, they did exactly what BioWare wanted: they gave players extra reasons to play Neverwinter Nights, extending the shelf life of the game, and they generated enough money so that BioWare could continue to add new tile sets and equipment and more to the Aurora toolkit, giving fans of the game more things to play with. The modules were all well made, and most were relatively fun, and so, as experiments go, you’d have to say that this one was a success, and I can only surmise that BioWare (or other companies) will attempt similar endeavors in the future."
