S.H.I.E.L.D, a shadow agency, whose secrets had secrets. They survived the chitauri invasion, and emerged stronger then ever with the Avengers. They survived many more situations on top of this, invasions, threats to humanity (from other humans and occasionally from extra-terrestrial beings).

They scattered to the wind.
