Lofnheid is the youngest of five siblings, born to the dwarven blacksmith, Hredimar and the dwarven healer, Svarri. She was born in the year, 2851, and lived in her childhood years with her family in a village of Woodsmen of Mirkwood, near Rhosgobel, the dwelling place of Radagast the wizard. Her early life would have been lonely, had it not been for her older siblings, Lyndheid, her sister, and her brothers, Fafnir, Regin and Ottr.

Of all her siblings, she is the least adventurous, preferring to spend her days working on the needlecrafts and jewellery making that her mother passed on to her, and looking after the sheepdogs that her mother bred. As such, she is known as a keeper of collies. Her early life with her family among the Woodsmen was a happy one, even if at times it was fraught with the difficulty of her family not living among their own kind. As they were the only dwarf children in the village, there was often conflict with the children of the Woodsmen because of their differences and when she reached the age where she started to grow a beard, she, like her sister Lyndheid, took to the practice of shaving it off, an habit which she continues now.

There were dangers growing up in the forest due to the increasing incursions of spiders and orc attacks, so in her early years she hardly left the village. Her two oldest brothers, Fafnir and Regin and Lyndheid were much more inclined to fight the darkness than she was.

Life was far from easy in the forest, being away from the riches of her people, and poverty was a constant problem for her parents, so when her brother Ottr was killed by a powerful being, and gold, plus a magical ring were given in ransom to her father to compensate for his son’s death, it was initially greeted with enthusiasm. Unfortunately, there was a curse laid upon the ring, and Fafnir and Regin both hungered for the possession of it and the gold, which resulted in the deaths of the brothers and her parents. Lyndheid, vowed to destroy the ring, so that it wouldn’t cause harm to anyone ever again, and took off on a quest to destroy it, leaving her sister in the Woodsman village. As time passed, there was no word of her sister, so Lofnheid began to suspect that her sister had joined her brothers and parents in the Halls of Mahal.

Harassment from the spiders increased, and eventually the village was destroyed, and assuming that Lyndheid would never return, she took her mother’s surviving sheepdogs and set out for a safer place to live, taking along with her the weapons that once belonged to her father and brothers. Lyndheid had taken their mother’s sword when she left to destroy the ring. After a dangerous journey, she eventually arrived in Lake-Town, where she lived until Smaug was woken from his sleep and destroyed the town. Eventually, after the Battle of the Five Armies, she took up residence in Erebor and met her future husband, Andvari and his brother when dwarves returned to the mountain. In addition to meeting her One, she discovered that her Aunt Bild was still living, who had taken on Andvari as her apprentice. She married Andvari and they had their first child, Nali, together, who was born in 2942.
