Born to the now-fallen Chelaxian noble house of Spiros, Chrysanthe (middle name Marcella) was the second child to be born a tiefling, the first being her older sister Sotiria (middle name Herminia) after many generations of fiend-blooded Sorcerers.
This taint was the result of the family's past dealings with fiends, as their family was not just known for skilled wizards and alchemists, but also for the dangerous associations they had to the Blackfire Adepts, which once led to a thanadaemon tainting their lineage. Though born into one of the most hated "castes" in Cheliax, the two girls were accepted by their family and quickly had their tainted blood hidden with a mix of illusion magic and well-placed bribes by their parents.
However, their peaceful times came to an abrupt end just as Chrysanthe turned 22, as her family was found guilty of heresy and chased out of Cheliax by agents of House Thrune. This led to the separation of the sisters and to the death of their parents as Sotiria escaped to Ustalav while Chrysanthe arrived at Varisia via Nidal. This experience has left her emotionally scarred and hungry for revenge, which she has waited to gain for four years while adapting to life in Varisia. Despite missing her mansion, she has grown fond of her new home, and has displayed interest in the region's history as well.
