Niamh has dark brown hair, which when it is not braided and  pinned in its usual coif, cascades  in wavy tresses midway down her back. While her face is often held in a mask of polite interest, her every emotion can be seen to flash in the depths of her large, gray eyes which will change color to reflect her stronger emotions.. A delicate nose, arching brows, and sensual lips give Niamh an innocent appearance, yet there is a decidedly determined set to her chin which may cause one to reconsider their initial assumptions.

Short and slender, Niamh favors clothing which will not hinder her as she wanders. She usually wears dark trousers tucked into black, calf-length boots and a nondescript laced shirt under a dark cloak which hides her tail and ears from sight. She is rarely to be seen without some sort of knife upon her person.

The young girl sighed internally as she struggled to copy the sentence before her. She would much rather be out exploring but her father had recently begun to insist that she required lessons in writing. She suppressed the desire to fidget. She did not want to read, write and figure; she wanted to be out learning by doing. The young girl took a moment to calm her thoughts before returning to her copying.

The young girl watched the knife, not allowing her attention to stray any farther than the man holding the weapon. Her father lunged at her, but instead of slashing at her, he feinted and dumped her on the ground. She rolled back to her feet in time to see the man lunge at her once again. The girl turned and grabbed at the arm holding the knife; she knew immediately that she had grabbed in the wrong place and braced herself to be dumped yet again. She knew her father would want her to pinpoint exactly what she had done wrong so that she would not repeat such a mistake. As she smacked the ground, the girl could not help but wonder if she would ever be able to master this.

The young girl felt exceedingly nervous as she walked behind her mother, the mother she so infrequently saw. She had a fierce desire to make her mother proud of her and so did her best to follow and obey without complaint while her mother instructed her. The girl was determined learn what her mother sought to teach her about stalking prey, so determined that she did not mind the discomfort of their travels.

The young girl became a young woman and she became much more adept at the lessons her parents attempted to teach her. As a result, her mother began to take her on increasingly more dangerous missions. Inevitably, the young woman came to a point when she needed to go off on her own.

Daughter of the Lunar, Twilight's Heart, and the mortal man, Bran. Twilight's Heart is part of a Retriever Pack which goes out to retrieve new Lunars. Niamh spent the majority of her younger years with her father, Bran. While Bran normally refrained from volunteering information about the majority of his past, he would occasionally recount the numerous fights in which he had used his knife in order to explain a tactic while teaching his daughter. It is from him that Niamh learned all she knows about knives. Niamh has no idea what circumstances brought her parents together. She knows simply that she had been born and left with her father as her mother walked in places far too dangerous for a small child.

     Niamh left her father's house in order to learn more about her Lunar heritage at her mother’s side. Twilight’s Heart began to take Niamh along when retrieving new Lunars in order to develop her tracking skills. Because of this, Niamh is somewhat known by the Silver Pact for her tracking skills Niamh learned a great from this; however, after having a discussion with her mother, Niamh decided that she needed to go off on her own in order to see how she could fare without someone watching over her every move. She had to learn how well she could take care of herself. Because of this, Niamh has been wandering northward on her own.
