Avengers #29, an Original Sin tie-in, goes back to some earlier Jonathan Hickman plots for the Illuminati.
The Illuminati, a secret cabal of the Marvel Universe's greatest minds, was brought together for a single purpose – to protect the world from the threat of multiversal armageddon. But to save our entire universe, Iron Man, Dr. Strange, Mr. Fantastic, Namor, The Black Panther, The Beast and Black Bolt would have to do the unthinkable.
To protect their secret, they tampered with the memories of Captain America – erasing his knowledge of their terrible acts. But no secret stays buried forever. And Steve Rogers is about to discover the betrayal of his closest allies.
We remember that…
Because, you know, if that was the Original Sin, then… well, it wasn't that original, was it?
More original sins to come, I'm sure.
