Written in tears, blood, and sweat. 

A new threat from the gloom of the unknown presents itself, and against overwhelming odds, the SGC puts all their training and experience to the test against a foe that is a nameless fear, that the Gou'ld, the Replicators, and even the Ori fear. The fight shall be bloody, costly, and heartbreaking, and entirely inevitable. 

 Nevertheless, the teams must fight on, or be destroyed entirely.

For on the Razor's edge, there is no room to flinch. On the brink of death, there is no time to beg.

But even then, it might still be too costly a fight to wage. 

The Ori are bearing down on earth and Atlantis has been compromised there is only one thing that can preserve human kind from earth. Not long ago a tablet was found saying that not all of the ancients that evacuated Atlantis ascended some of them left for the Orion galaxy there was no exact location but it is possible that the ancients that left to the Orion galaxy are still out there. The Odyssey, Daedalus and Prometheus leave for a random location inside the Orion Galaxy.
