The story of "Shield" begins in what would be the '50s and '60s of the Marvel Universe. "This is, of course, relative to Marvel's sliding scale time line. When doing something like this, we have to wink at some of the previous stories from that time period, and sometimes we have to massage some of the others and try to make it all work (the perfect example of this being Sharon Carter from "Captain America," who started out as the little sister of Steve Roger's WWII girlfriend and later had to be changed to her niece - the story just doesn't work anymore if you don't fudge it)," Hickman explained. "Anyway, we start with a normal guy, just like you and me, who's snatched out of his daily life and swept up into something bizarre and wonderful, what is essentially a whole new reality. We'll then, of course, find out that he's much more than a simple boy. Blah, blah, blah... Joseph Campbell mixed with my own special blend of dysfunctional weirdness, and we're off."
The Golden Age of the Marvel Universe is just where the story of "Shield" starts. Early on in the book, the action will flash back to ancient times. "We jump back through time and see the first alien invasion that happens on the planet. I'm not talking about the Celestials or any of that stuff. This is more along the lines of a straight up, 'humans repel alien invaders' event that happens. We see what gets born out of that, how it transforms society, and how that evolves through the history of man," Hickman revealed. "We start our flashbacks in the third dynasty of ancient Egypt with a man called Imhotep. He's considered the world's first polymath, which is another word for what's commonly referred to as a 'Renaissance man'. We never state this in 'Shield,' but that kind of becomes the requirement for somebody to be part of the organization. That's the type of men and women that the Shield is looking for. It's only natural that Renaissance men big guns, like da Vinci and Galileo, feature and feature prominently"
Making up the main and supporting cast of "Shield," Hickman has assembled a collection of historical figures, established Marvel characters, and original creations of his own. "I would say our main cast is around eight to ten characters. Very early on, we're introduced to Nathaniel Richards, the
father of Mr. Fantastic, Reed Richards, and Howard Stark, the father of Iron Man, Tony Stark. The young man I talked about above is named Leonid. He's the Eternal Dynamo... the great engine of the human machine. He represents progress, the advance of society and all that other cool stuff," Hickman said. "There's also a guy called The Night Machine who is the opposite of Golden Age Renaissance heroes like da Vinci, Michaelangelo, and Galileo. We'll see the dark dreams of Nostradamus and we'll unflinchingly answer the long-standing question of whether Isaac Newton was the first man of the age of reason or the last of the magicians. And, hey, why be boring... let's stick a Celestial, Galactus, and the Brood in the first issue and see what happens."
Because "Shield" is a story that flashes back and forth between various time periods and spans thousands of years, it will be structured differently than other ongoing Marvel series. "It's probably best not to think of this series in arcs. It's really not that kind of story. This is a bit like 'Secret Warriors' in that it has a beginning, middle and end, but the comparison probably falls apart after that. "Shield" is not a mini-series. It's an ongoing, but it's also a finite story," Hickman stated. "I'm honestly not sure how many total issues it will be, but it's simply not an arc-driven thing. I know there's a tendency to do that because of the marketplace, and God knows we all want to do our due diligence in being commercially relevant, but this isn't that kind of story. There's no real way to break the pieces up. It simply fits together a certain way."
