PoV ???
The girl lived off absorbing other people's life force; at first she did it unconsciously, but when she learned how to do it, she started draining all her enemies of their life force, turning her own colder and colder.
That process slowly changed her body; her skin became more and more pallid; it looked cadaveric at best; her hair turned white; and her eyes turned red. The changes did not only affect her physical aspect, as even internally her body was changing.
Slowly she had begun to lose her sense of touch, then the sense of smell, and lastly the sense of taste; however, she did not care; so long as she could follow the trail of chaos and murder of her beloved hero, she was ready to lose even her sight and hearing sense.
She wandered in the lands, freezing everything in her way, turning the once beautiful landscape into an arctic hellhole. Eventually, her powers grew too strong for her world, and she was forced to ascend.
