"You like stories, Guardian?" Variks says in thoughtful contemplation. "Then come. Sit with me. Let me tell you about the time lost Vex, yes?" "The Vex have no beginning or end. They cannot be created or destroyed. They are forever stuck in a long section of time, yes? Racing back and forth. To fix what is broken. Like a ball on a string. "They see our existence as one giant machine. A machine that is in constant need of rebuilding, repairing. Until everything works in a smooth flow. And you, Guardians, are the bugs in that machine. The imperfection that destroys their flawless works. It is why they seek you out. Destroy you. Eliminate you. I know this. House of Wolves kept close track of the Vex. Stole secrets before House broke and I sided with the Queen. But secrets and House were taken by Skolas. Said he would conquer the Vex and make his word their will. "But I was no fool. Knew Guardians would destroy Skolas. So, secrets I stole back. Now, I hand these to you, yes? They tell of a large metal block at the end of this galaxy. Large like a planet and silver in color, it is what chains the minds of the Vex together. Keeps them in constant contact with each other. And replaces the holes in their ranks. Find it. Destroy it, and erase their stories from the pages of our history."
