You were in the middle of a mission in a Corpus spaceship. The enemies just kept coming, as if there were almost infinite of them, you barely could handle it anymore, and you felt how your warframe was about to get destroyed at any moment...

Suddenly a warm green light surrounded you, and you felt how your warframe started healing, meanwhile all the enemies around you were getting completely annihilated, you turned around and saw her, flying with her wings extended under a ray of blinding light, as if she was an angel sent straight from heaven

She closed her wings, covering her face and wrapping them around her waist, which covered her from the stomach to her feet, like a long white skirt. She then approached you, and extended a hand to help you get up

"Let's get out of here before more come."
