Editing Desmond Miles (section)

===Sacrifice=== 

:''"You know it's true. It's already started. I need to do this now. So go! GO!"''
:―Desmond's final words, to his father.

After reliving more of Ratonhnhaké:ton's memories, Desmond learned that the Assassin eventually buried the key to the Grand Temple's barrier outside of the Davenport Homestead manor in Massachusetts. The team traveled there and retrieved it from Connor Davenport's grave, before they returned to the Temple. Using the key to open the final gate, Desmond, William, Shaun and Rebecca proceeded into the Temple's deepest chambers.

Upon arriving in the central room, which contained a large orb set in a pedestal, the Assassins were greeted by Juno, who stated that should Desmond touch the orb, the world would be saved. However, immediately following this, Minerva appeared, urging Desmond not to touch it. She explained that Juno had previously tried to use the First Civilization's technology to conquer the world rather than save it, and that she was sealed inside the Temple so she would not be able to do so. While the device would save the world from the impending solar flare, it would also kill Desmond and release Juno, allowing her to continue her quest to rule over Earth.

Shocked by Minerva's appearance, Juno told her to show Desmond what would happen if the solar flare was not stopped. Minerva stated that while the majority of Earth's population would die, there would be a small amount of survivors. Desmond would become a symbol of love and hope for the new world, similar to Jesus Christ, though following his death, his message would eventually be misinterpreted and corrupted by those who followed him, and lead to war, thus repeating the cycle of religious conflict through history.

Despite this, Minerva pleaded for Desmond to let the world burn instead of saving it and releasing Juno. Desmond stated that if Juno was released, there would still be the slim chance that humanity could stop her, while if the world was allowed to be subject to the natural disaster that the solar flares posed, billions would die, and there would be no hope. Acknowledging Desmond's decision, Minerva stated that the consequences of it were his "to live – and die – with."

With his mind set on his choice, Desmond turned to William, Shaun, and Rebecca, and commanded them to get as far away from the Temple as possible. William pleaded for him to reconsider his decision and find another way instead, but Desmond refused, stating that it was too late to find another option. With this, William, Shaun, and Rebecca hurried to leave.

After the three exited, Desmond walked up to the orb. Juno watched as he touched it with his hand, his body shook violently for several moments and shone a bright gold; though, after a brief time, Desmond fell to the ground, sacrificing his life to protect the planet from the Second Disaster. Later, she was seen walking away from his body, thanking him for releasing her.
