I have been thinking about Darksun for a while now. Problem is, there is little for campaign world rules that I like. So....
Would there be interest in a PbP Darksun if I posted a handful of game rules (mainly with Divine & arcane magic and weapon use) with pre-gen characters?
There is interest so I'll see if I can find my Darksun book I created for 3.0 a while back and adjust it for 3.5.
If you have ideas for characters please post them and I'll see what I can do. Some are easier than others. Thri-kreen is nearly out at 3rd level because I won't use the humanoid Thri-kreen. I really do prefer the 2e Thri-kreen and Tohr-kreen. I'll see what I can create between Savage Species and my 2e Thri-kreen book for racial levels.
As for house rules, most are simple. Like for Clerics, one Domain must be an element and the other chosen domain must relate to the character specifically somehow either by race or personality.
It was alway how I handled defiling that was an issue.
I'll work on it and hopefully in a week or two begin posting something within the Rogues section (I'll set up a link to here).
