In May 2012, a member of SHIELD was killed in the Chitauri invasion. Not even days later, four of his most notable agents disappeared without a trace, leaving nothing behind but stories of their missions. Only the director, deputy director, and two of the Avengers knew anything about them.

In September 2013, one appears in Chicago, Illinois, another in Manhattan, New York. A year later, a third comes to Chicago. After the Triskelion and SHIELD falls, the last makes his way from Manhattan to Chicago with a warning - beware of HYDRA at all costs.

To the streets of their cities, the Four Crowns are heroes. To the highest rankers, they're stories that deserve to be left as that. After three Crowns strike at the same time against their highest targets yet, there's no denying they're just stories any longer.

And with more enemies swarming than ever, the lives of those working at Firehouse 51, the 21st District, Chicago Med, and the Manhattan Special Victims Unit will turn on their heads when they see sides of their coworkers they never have before.

One day I will stop thinking of crazy plots for my fandoms . . . one day. That day is not today, apparently.

My love of the Chicago and L&O: SVU shows kind of exploded towards the end of summer when on my days off of work, my mom would be watching them and me, either napping or working on my computer, would start getting more hooked, too. Thus, here I am, planning on mixing them with Marvel, of all things. I think something's wrong with me. XD

Oh, well. Y'all get a new story out of my madness, so hopefully it's a win win. XD Stay tuned for my main pairings . . . though if you've paid attention to my message board and the cast list, you might already know. XD
