Natural treasures under park... this place a reference?
Deserts suck.
Addendum, living in a desert sucks.
It's hot, it's sandy and there's basically nothing to do in them except getting sunburned, dealing with dehydration unless you know an oasis, a guy, or have the ability to see the future and maybe get eaten by vultures...or particularly vicious armadillos...
However, the denizens of Stone Claw City figured out a way to bring little bits of more pleasurable environments into the desert, to be more specific, into giant underground caverns that could be modified with a mix of aether crystals and arrays up the ass.
By carefully arranging both in the right way, one can turn an abandoned mining hub covered with tunnels leading evewhich way, into a brand spanking new nature preserve full of mundsnce plant life complete with small water fixtures.
