Lux

Lux’s dad is a famous leather worker who is known for super intricate designs in all of his work. In one of his pieces he accidentally inscribed a spell to summon a strong demon. They were amused that this dude had accidentally summoned them and was impressed by his precise work. He began to work their symbol into all of his work so they could keep meeting and they fell in love, thus Lux and her older sister were born.

Her sister always had a natural aptitude as a close combat fighter growing up, but Lux always struggled to keep up in their spars and grew frustrated. Her demonic parent became fed up with Lux’s temper tantrums and decided to take her training into their own hands. From then on, Lux was granted powers as her parent’s patron. Lux is kind of embarrassed that her parent had to help her and hides who her “great and mysterious” patron is.

Lux’s sister grew apart from their father and didn’t want to become a leather worker, so tension started to grow in their family. Eventually came to a breaking point, and her sister left home to become a knight in the army, where she felt her fighting prowess would actually be appreciated.

Lux was (and is still) prone to violence, so when her sister tried to leave Lux tried to stop her from leaving with force. After a quick scuffle, her sister won and left her behind.

Lux left soon after, chasing after her sister and trying to find her to bring home.
