You're exploring the area near the android camp when you hear a Machine nearby being suddenly destroyed. Grabbing a weapon, you quickly run out to investigate the situation. By the time you get there, the entire squad of enemy Machines has been cleanly sliced to pieces, with one lone figure standing among the bodies.

Her lengthy, elysian white hair flows gracefully in the wind, her long greatsword buried halfway into the ground to let the oil from the Machine she just slew drip off of its blade and into the soil below. For a moment, she looks contemplative, as if she has done this a thousand times already. Maybe she has. She watches expressionlessly as each drop of the Machines' vital fluid runs down her blade and into the ground, as if slaking the thirst of the Earth itself for the blood of its alien invaders.

Then, she turns her head to look back at you over her shoulder.
