Speculation Specialist Wizard
I'm wondering the same thing. I was almost sure that including the thri-kreen in the Spelljammer UA meant Dark Sun was on the horizon, but including them in the SJ book (along with those Dark Sun minis) makes me think it's off the table.A bit surprised just how many Dark Sun creatures are apparently in new Spelljammer. I wonder what this means for Dark Sun itself.
I may still keep hope alive, though!
