Here's the list of all the hakpacks and other downloads needed for this module:
Main Stuff The primary hak and tlk for the module. The tlk goes in your tlk folder.
Skyboxes Ok, this one is rather large, but the skyboxes are really cool. I believe this DL is effectively optional, though.
The CEP (Community Expansion Pack). If you don't have this, you should get it for whatever modules you play/work on, 'cause it rocks!
Guns Yes, we're a bit crazy here, I suppose. Gnomes with guns. Well, they're still gnomes. ;)
Mountains A rather keen hak with tall mountains I got off the NW vault. I can't find the original place I got it from, so, here it is.
JXP For convenience, I compressed the required JXP files myself. These are also hosted on the Vault by their author. All the JXP haks are superb.
Override files Unzip to your NWN override directory (This is heads and stuff)
Portrait files Unzip to your NWN portraits directory
The Rest This includes pas_desert_ad_1a, pas_elfcitint_1c, and arabcity haks. I couldn't remember where on the Vault they came from, so.

Totally Optional Stuff
The World Map for the module
World Map with area designations
Guide to the world map (excel file)
