Reunited. 

Glad you asked! Yes, they're in a desert, and I get iterators mainly revolve around using a bunch of water, but the ancients building Tested Dunes obviously didn't have much of that to work with, so they decided to go with something else just as abundant- the sunlight. TLDR: Tested Dunes is basically just solar powered lol

The water the other iterators use is for cooling their systems down so they don't overheat.. How does this one keep cool in a desert?

@@femboygaming64 never really thought that far yet, but i'll try and think of something lol :)

underground water reservoir ​@@chocoramenLOL

That's a good idea tbh
