Nyx was born in the city of Alliria. Her father died when her mother was pregnant and her mother died in childbirth. She was raised in a very religious orphanage, where, in the library, at the age of thirteen, she found a few books detailing demonic rituals and necromancy, or, more accurately, how to avoid those who practice it. But the books intrigued her, and in one of them was a ritual meant for summoning and controlling Maniae(Greek mythological spirits of insanity). One of these spirits guided her to find, in another library, more books on necromancy. She studied for about a year and six months before a thought struck her: what if she used the magic she'd been steadily mastering to bring back her mother?
Unfortunately, the best time to easily resurrect someone is right after their death, and Nyx's mother had been dead for fourteen years. This didn't stop her from developing an obsession with resurrecting her mother. It took several years of failed attempts and concerned friends asking why she wasn't eating and why skeletal wings were growing out of her back(a deformity that was a result of attempting to sacrifice part of her own soul to speak with her mother's) before she finally decided to give up. She has been traveling the world since then, making a living performing favors for people in need: usually only helping people speak with deceased loved ones(which does not cost a human life), but occasionally bringing them back. She avoids working for anyone well-known, as she likes to keep a low profile.
