I have been working on a custom module since soon after the game’s release, and I think I finally have it finished. It is available for download here. NOTE, I just uploaded version 1.6, it may not show up for a few hours at this site. v1.5 is playable but there is a quest and a merchant that do not function properly in it. If you go to see it and it still says 1.5 you can still have fun with it (the broken quest is one of the most difficult to do and the broken merchant is often overlooked by players).
This module started out as just a silly experiment with the module-building tools, but as I learned to do more the scope of the module expanded, and now it’s rather large and full of custom monsters, custom scripting, and custom items. It is basically a parody of old bad dungeon crawls I’ve played in the pen and paper game, but there is backstory and some rather dramatic writing hidden away that I’m rather proud of. Have fun with it.
BTW, if this module gets enough positive votes it will get more exposure, it has slid off the new releases list and though it was the 28th highest rated module they no longer show those that far down the list. If you like it, give some feedback at the site.
