Dang, bottom in my mind I thought so too.
I'll keep my expectation low then, but I'd be happy if we're to be proven wrong.
I hope they're not cocoons either but they look like the same kind of technology cocoons are made from. Even if it's a barren wasteland they still look like they take up more space than a regular cocoon.
While Aelios is rather big, once I got my barings around it it isn't that big. If anything rather boxed in with mountains and oceans. That said if Retem is roughly the same size as Aelios I'd be dissapointed. Especially if pyramid cocoons take up so much space in Retem.
