Forgive me if this has been covered exhaustively elsewhere. Additionally, I no longer have any of my Dark Sun books and can’t really reference them with regards to my inquiry.
I seem to recall the Wanderer from the 1st edition boxed set waxing poetic about the Green Age being such an era of prosperity that warriors could afford to encase themselves entirely in metal and undertake violence for the sake of mere honour. That, and a few references to castles and the like in the rpg books, as well as a few in a Kevin J. Anderson short story I read once (featuring a minotaur merchant seafarer from the lost age, no less!) lead me to think the Green Age was analogous to the idealized medieval Europe of most fantasy rpgs.
That said, Mind Lords of the Last Sea, if I remember correctly, purportedly centered around the intact Green Age city of Saragar, which seemed to have a Bronze/Iron Age Aegean look and feel.
I realize talking Dark Sun canon is a bit like trying to talk Traveller canon (the gulf between Megatraveller and the New Era alone…), but I’m curious what everyone’s impressions are, even if they’re merely preferences and interpretations.
With regard to religion, I remember a passage from the first Dark Sun novel (the one with Fabio wearing a leopard skin on it… Agis of Asticles, perhaps?) in which the characters encounter a forgotten temple in under-Tyr. The temple springs to life in the their presence, suggesting at least a residual divine power. Is Athas similar to Krynn in that the gods abandoned it, or are we meant to believe there never were any gods? If the latter, can anyone think of any references to the religions of the Green Age, be they merely the mention of lost temples and the like?
