The Aurora Toolset is a powerful and simple-to-use tool that allows players to change many aspects of Neverwinter Nights, create new modules using themed tilesets and turn many ideas into in-game reality. It does not, however, support plug-ins or other third-party extensions. This is the same tool used internally by BioWare to create the official campaigns (and the modules comprising those campaigns can be viewed in the Toolset, once they are played through or otherwise unlocked).
