The Sentry, Vol. 1

At long last, The Sentry has returned to his fortress... the Watchtower. Here lies the answer to the mystery that has been plaguing him... the mystery of his nonexistence. But even as he brings to an end the world's forgetfulness of him, he is faced with a betrayal at the hands of his best friend... Reed Richards. But the betrayal will have to wait... the Sentry's mortal enemy, The Void, has returned and his very existence threatens more than the Earth. Desperate for assistance in confronting the Void, the Sentry calls for all superhumans to come to his aid in what may be a final battle.
