S.H.I.E.L.D.

Leonardo da Vinci was an agent of S.H.I.E.L.D. So was Issac Newton. So were Imhotep and Zhang Heng and Galileo and other geniuses throughout time. They were the first heroes to defeat Galactus and the Brood and turn back Celestials. They saved the world long before Captain America or Iron Man were ever born, but what does this mean to our heroes of today? What does this mean to Nick Fury? Michelangelo has been pulling the strings for years, but can even he keep da Vinci and Newton from killing each other and destroying the Brotherhood of the Shield? The battle for the Immortal City is on as the truth behind Nostradamus is uncovered, and Howard Stark lays the foundation for the espionage organization you know and love! But the battle that decides our present will be fought in the future!
