We are working on a NWN Dark Sun Server with mostly all custom content.

We have all of the following so far.
- Races - all the Dark Sun playable races working
- Classes – all the Dark Sun playable classes are working
- Custom Armor
- Custom Weapons
- Custom Skyboxes
- Custom creatures (we even have working Dragon King and Avangion models)
- Totally New Custom Desert Tileset
• Raised ground
• Hills
• Cliffs
• Main City Walls, Main Gate, Stairwell towers, Battlements and so on.
• Adobe City Buildings
• The Ziggurat for the City State of Tyr
• The Arena for the City State of Tyr
• Water

There is still a lot of work to be done yet.

A lot more custom
- Tilesets to be made yet
- Creatures
- Weapons and Armor
- Placeables
- Scripts
- Area Building

So we are looking for more people who would like to help with this project.

I can probably help with the scripting. I have experience with LUA, Python, Javascript, and others. I sent you a friend request, so we can talk more in PM.

Edit: I checked out the NWN scripting language, NWScript, which is what I'm assuming you will be using. It looks pretty straight forward, so I think I would be able to help you, if you still need help.
