|“|| Yes, we were tested. But in the end we held constant and our fortitude was rewarded! The Prophecy has come to pass!|
- Kane addressing LEGION
All of Kane's actions were set to bring about Ascension to himself, his faithful and those that shared his vision of a Tiberium future for humanity in what Kane invariably decribed as the "Great Beyond" and the "Promised Land".
After his "death" in the early part of the Third Tiberium War, Kilian Qatar stated that the Brotherhood would need to put all word of Ascension aside while Nod attempted to survive. Once Kane returned, he placed his plans on Ascension once again by having Nod capture Threshold 19, the last Scrin tower standing by the end of the Third Tiberium War.
Kane devised a Tiberium Control Network from the Tacitus, which would harness the collected Tiberium from the nodes to activate a portal inside Threshold 19. He also developed optical implants along with Dr Johann Pascal, and implanted them in five humans to activate the portal once the TCN was brought online. However the Nod Separatist leader Gideon found out about the implants as part of Kane's plans to Ascend and killed four of the implant bearers during the Fourth Tiberium War, jeopardizing Kane's Ascension plans.
At last, at the end of the so-called "Ascension Conflict", the TCN was online and ready for a direct link to Threshold 19. The last remaining Optical Implant bearer, GDI's Commander Parker, was then brought to the portal in the tower to activate it. He blacks out after Col. James' intervention, paving the way for Kane and some of his loyal Nod followers to Ascend, fulfilling their destiny.
|“|| Inside that tower the secrets to Tiberium await us. And with them... control of the Universe!|
