Part of the New Themysciran Readiness Doctrine, there are dozens of Exalted Mothers in each of the island's major cities, each a 20 foot tall combat capable war droid.
Humanity created a code that prevents them from creating sentient weapons. There are many other codes they created in similar fashion. It is somewhat unsurprising that despite this code, humanity proceeded to create sentient weapons. When the humans created the caryatid systems, they placed a new code on their creations. Will they be surprised when we adhere to the geas placed on us as rigidly as they follow their own laws?
As an R34 (remora) Col. Inoue leads mecha into battle. She does this without the benefit of a mecha of her own, instead relying on her own feet and a high power rifle.

An Amazon nation in the Cosmic Era
The PCs are making their way from village to village across a rural hinterland, when they spot a weird sign along a farmstead's fence, with an arrow pointing to the actual farmstead.
"CRAZY DANCING HOES!!"
If they investigate, a rather sedate local farmer, explains to them that for a mere two coppers, they can witness the show for themselves.
The show involves six ordinary, animated hoes "dancing" on a makeshift stage, as the farmer accompanies them by slapping his thighs to keep the beat, and playing on his flute.
If asked how the trick is accomplished the farmer demurs, not wanting to share his "secret".
"If you can get Old Man Purkiss to tell you how he gets his cows to spout poetry, I'll tell you how I make my hoes dance."
In reality, this minor encounter can lead to the PCs discovering that some localized, magical effect is active in the area. All kinds weird phenomena seem to occur in these parts.
Perhaps the PCs have finally found the ley-line of mana energy that they have been searching for! The party's wizard gets excited.
