Gaines was hugely relieved, at least until September 1943, when a letter arrived from John D. Jacobs, a U.S. Army staff sergeant in the 291st Infantry, stationed at Fort Leonard Wood, Missouri. “I am one of those odd, perhaps unfortunate men who derive an extreme erotic pleasure from the mere thought of a beautiful girl, chained or bound, or masked, or wearing extreme high-heels or high-laced boots,—in fact, any sort of constriction or strain whatsoever,” Jacobs wrote. He wanted to know whether the author of Wonder Woman himself had in his possession any of the items depicted in the stories, “the leather mask, or the wide iron collar from Tibet, or the Greek ankle manacle? Or do you just ‘dream up’ these things?”
The inspiration to give Diana bracelets came from the pair of bracelets worn by Olive Byrne, creator William Moulton Marston's research assistant and lover. "Wonder Woman and her sister Amazons have to wear heavy bracelets to remind them of what happens to a girl when she lets a man conquer her," quoted Marston in a 1942 interview. "The Amazons once surrendered to the charm of some handsom Greeks and what a mess they got themselves into. The Greeks put them in chains of the Hitler type, beat them, and made them work like horses in the fields. Aphrodite, goddess of love, finally freed these unhappy girls. But she laid down the rule ("Aphrodite's Law") that they must never surrender to a man for any reason. I know of no better advice to give modern day women than this rule that Aphrodite gave the Amazon girls."
Having learnt of Wonder Woman's inability to return to Themyscira, Doctor Veronica Cale, a wealthy and powerful woman, set into motion a plan to use Wonder Woman to find Themyscira. Years earlier, Cale's daughter Izzy had her soul stolen by the gods Phobos and Deimos. They told Veronica that they would only return her daughter to her if she helped them find Wonder Woman, and got the location of Themyscira from her. Seeing no other option, Cale had formed a team called Godwatch, dedicated to locating Diana and Themyscira.
