What is the best info avible on Dark Sun? I know a Dragon and two Dungeons had some info recently, but only one is none PDF, and I'm not a big Fan of PDFs. I'm planning on sending my Eberron party there though a portal in Xen'drik. Many of the worlds races orginated there. Edition isn't very important, but I would slightly prefer 3 or 3.5 (I'm just going to use the flavor mostly an maybe some monsters. As a side note, are the two Dungeons and the Dragon any good?
Go to athas.org. They have 3.5 rules for PCs and conversions for every single Dark Sun monster. And they're rather good, and much more extensive than the Paizo magazines had room for.
Both athas.org and the version printed by Paizo are accepted as official sources for Dark Sun material. However, the two do not match, crunch-wise, so you'll have to take careful notes on which of what you want. They're both good, just in slightly different ways.
Thanks a lot. By the way, how do the PDFs work?
