Yeah the links I shared are the sourcebooks for 3.5 Darksun. There was some stuff in Dungeon magazine #110,#111 there is also some stuff in Dragon Mag. #315 and #319 but it is not the source that I used. Athas.org which has been around since 2000 created 3.0 and 3.5 rules and campaign book for Dark Sun when Wizards did not release it as a campaign setting for those editions.
Hmm...I'm not really sure if I want to change it again. Certainly if more data gets added it's something we should consider. I'll put it on a list somewhere to monitor.
