Niv was born a regular lasirus, living her life in Centropolis and doing the usual batty things. As she grew older, she developed a fondness for looking her best, grooming her twilight fur daily, and even fashioning her formerly bushy tail into a luxurious, dainty pouf. She enjoyed collecting dark, ornamented things and had a separate collection of mirrors which she constantly used to admire herself.

On one particular evening, Niv found a larger mirror, the black frame carved with detailed roses and twisting thorny vines. Wondering who would throw out such a thing, she clutched it to herself and flew towards her cave. As she flew, she couldn't help but look down into the smooth glass, catching her reflection in the moonlit night. Mesmerized by how she looked framed by the beauty of her mirror, she failed to notice a power line in her flight path, and flew right into it. Her wings tangled in the power line, zapping delicate skin and bones before finally falling towards the hard ground.

Niv awoke in a strange place, surrounded by strong smells and darkness. She quickly learned she was rescued by a sheeta witch named Vivi who had happened upon the little bat during one of her rare trips into the city. The witch did a a great job of healing her wounds, but Niv was horrified to learn she lost her eyesight and her wings had become so tattered, the skin had to be completely removed. Anguished, the poor bat felt bitterness towards Vivi - she should have just left her to her fate. The witch felt annoyance at the ungrateful creature, but at the same time felt an urge to do something for her. So, she spent many long days and nights teaching the lasirus how to sew - a feat considering she had just her long claws to aid her. But steadily, Niv improved and with it, her sadness dissipated.

She sewed cloaks and curtains and all sorts of things for Vivi's small house, and eventually learned to sew delicate lace with black spider's silk. By this point, she had sewn her own eyes shut, just lashes and thread where her large eyes once were. Still, even without her sight, she longed to look as lovely as she once did, so she fashioned her own set of wings from the lace she sewed even if she could still not fly with them. With her spirits lifted, Niv set out on her own, settling down in a cave in Shadowglen where she continued to keep up her appearance for whomever would set eyes upon her, and learned to grow comfortable with the fact that at least in her mind, she was the most beautiful lasirus that lived.
