The team was doomed from the start, or so it would seem. All of them hadn't practiced actual fighting in years, while Talon was sending their best fighters, yet they still had to fight over the point if the world had any chance of going on happily. Lena lead the charge getting on the point first and for awhile it seemed like things were going well, until Widowmaker stepped up her game. She shot down several of her foes. Lena couldn't believe what she was seeing. All of her closest friends and companions were dying in front of her. Memories flashed through her mind, and rage boiled in her heart. She began fighting more fiercely, despite being the only one left, but to no avail, as Widowmaker eventually shot her and she fell down into the hole at the center of the point, presumably dead.
Lena woke up. Injured, but not dead. She got up and found herself in a blue cave of bright dots scattered around. She then saw a bright blue disk lying on a pedestal in the back of the room. She found herself drawn to the disk and quickly went to it and touched it. She suddenly heard voices of a language incomprehensible to most humans, but not Lena. She understood perfectly, and knew what to do. She let go of her bonds to nature, and let her spirit converse with the disk, at some point, the blue light left the disk and went inside Lena's body. She herself was bright blue now, and felt incredibly powerful, she then flew out of the cave.
The Talon members were only waiting for the point to be completely taken, when they saw a blue pillar rise out of the whole, Lena's new form emerged from the pillar and immediately brought her teammates back to life, and then immediately killing all of the Talon members.
After the fight, Lena had Winston study her. Winston could not believe his eyes. Lena had become a goddess. Not only that, but she had the ability to make whoever she wanted immortal. Lena decided to use this ability to make all of Overwatch immortal, which allowed it to protect the world forever. She also made Emily immortal, so she wouldn't be lonely. And that's the legend of Lena Oxton.
