Nearly ten thousand years ago, a little ship called the Pilgrim is being pursued by a new and terrible force. It escapes, but just barely. It leaves behind a galaxy that sees the rise of a dangerous and evil new race of beings that will, in the years to come, chase out the dominate and more advanced Lantean people. Fast forward to the present day and Dr. Daniel Jackson, having spent the last few weeks on Earth to be with his ailing friend and leader, Major General Jack O'Neill, is preparing to return to the Pegasus Galaxy and the Ancient city of Atlantis. He and a small team of scientists have been searching through the Ancient database on Atlantis for a way to track down and reach the mysterious ship Destiny, lost somewhere on the other side of the universe. Their search leads them to the discovery of a forgotten computer system known as Seegan. Seegan holds many secrets and many solutions to their problems, including Stargate Command's inability to find the Destiny. While Seegan tries to locate the missing vessel, he recounts to Daniel Jackson and the others the lost history of a figure very familiar to Daniel and the Stargate Program. It's the kind of story Daniel has been wanting to hear. It's a tale about a time at the height of the Ancient's history. It's a story that starts at the beginning of their end.
