I do agree with Professor C in that I think that anything an "Athasian feywild" might have would probably just be better on Athas itself. Athas is already turned up to 11. There's not supposed to be a higher setting. Any higher setting makes Athas not the highest setting anymore, which weakens it.
Right. You don't need other planes because Athas is hell. If there were other planes that you could actually survive on, the campaign would be over as soon as the PCs could access them. Because only a total screwball would stay on Athas willingly... the place is just one jot above "all human life dies" on the scale of habitable planets. The one consolation is that everybody gets to be a Sardaukar/Fremen thanks to selection pressures.
There shouldn't be some nice retirement home in boca raton that you can just BAMF into whenever you want a nice ice tea.
Unless it was actually located within the mouth of a ginormous rat that was slowing closing and there was no way to stop it. Then you'd have the doom and pathos back. And the rat's throat is really dry.
I hope they make Dragonborn Cool.
Even if they all drove Lamborghini Gallardo SEs (Ithaca Verde of course) and dated clones of Scarlett Johansson that would barely put a dent in their uncoolness.
I hope they let everyone dabble in psionics.
And here I break ranks with DS traditionalists. I hate psionics. That's just me I guess.
