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?

The adventure can take place in a slightly shifted reality, where everybody has a totem (an animal guardian). The totem should be chosen randomly and not by the player, it is ok if "Gorflin the Large," a gigantic and aggressive barbarian, has a mouse for a totem.
These totems will assist the characters in small way. It is up to the characters to determine how to get the assistance; the animals won't solve mysteries for the characters only supply the clues. The character may even have a dream where his or her totem actually speaks to them and reveals some sort of clue.
