  Quotations
  But it was much more than a mere ship. Its systems, processes, and technology were so advanced that they dwarfed every accomplishment of the Citadel species. Its grandeur and complexity rivaled the greatest creations of the Protheans—the mass relays and the Citadel. It may have even surpassed them. And if Saren could learn and understand how it worked, he could seize all that power for himself.He’d spent his entire life preparing for a moment like this. Everything he’d ever done—his military service, his career with the Spectres—was only a prelude to this revelation. Now he had found his true purpose; destiny had led him here.
