So does that mean that Rajaat is alive, or did he die some other way? I assume Tyr is still a free city since that was its central theme, and contributed to the potential weakening of the Sorceror Kings.
Then again, I could just buy the books and answer my own questions (and all the ones your answers will create).
I always loved Dark Sun. I hope they did it justice.
I think they did Dark Sun justice.
Rajaat isn't mentioned at all. The Campaign guide is a lot like the original box set. It sets up all these great locations, themes, and characters, and then wants the DM to use those as tools. They do mention the Prism Pentad novels, and say "that may or may not be the story of your version of Athas". So if you want Rajaat to still be imprisoned in the black with the Dragon as his warden, you can.
It really does hearken back to the 1st box set in setting up this savage mysterious world, and not shackling it with canon. Thats great, since the 2E version got really bogged down in the cannon they introduced. The Prism Pentad blew up the world basically and the revised box set tried to expand it out a bit to give people some breathing room for games. 4E basically hits the reset button, but retains some of the cool stuff that came out afterwards.
The Campaign book is great, and the monster book has lots of goodies. I wasn't taken with the adventure, but I might warm to it after a second read through.
