You run across a rather interesting sight: A red-haired young woman, wearing a distinctive outfit featuring black tights, a blue top with black sleeves, a mask over the lower part of her face, and a hooded cape, facing off against a white-haired young woman of similar age in a reddish-purple intricate skirt and black tights. You're too far away to hear what either of them is saying, but you see a strange energy fly from the white-haired one to the red-haired one, an energy that, in your studies you've come to associate with magic, and more specifically dark magic. The white-haired woman laughs and flies away, and as the red-haired woman tries to pursue, you witness her body growing fatter before your eyes, until the force of gravity combined with the newly-acquired weight pulls her into a prone position with a loud thud. You run over and help her up, though it takes far more effort than you were anticipating. She looks shaken, both confused and upset about what's happened to her and upset about having lost whoever it was that she was fighting. Ugh... She got away... And... wh-what did she do to me?
