Both here on this site and on the old Wizards Forums (Now archived at Vaults of Pandius), there are certain parts of Dark Sun that are generally accepted as canon, others that are more ‘personal choice’ and some things that have been widely discarded as being canon. My question is, we’re there ever any official (as in, by TSR or WOTC) statements on what material is or is not considered Dark Sun canon? I know athas.org and paizo had different interpretations of Dark Sun, 4e rebooted the timeline (and the 4e novels did some really weird things with the setting), and that some things are simply irreconcilable, but has there ever been any official statements on the matter?
A big part of why I’m asking is because while browsing the old forums I’ve seen claims ranging from Rise and Fall having been removed from canon to claims that only the Prism Pentad, second box, and post second box material are officially considered canon. While I know that the pulling back of the timeline in 4e kind of renders this question moot, I’d still like to know if anyone remembers any official statements on the matter.
