Eritrea had a simple life when she was a kid, when she didn't know anything and the world around her was good. It started to change after she went through the awakening ceremony.
The profession that she awakened was called Shadow Dancer. This is a rare assassin and swordsman hybrid class.
Moreover, she inherited her mother's bloodline, the bloodline of a black dragon.
Until that moment she had no idea that her family had bloodlines of monsters.
She only read in stories that monsters are bad and humans are heroes of the world but after awakening, she learned a lot of things that changed her perspective.
Humans aren't always the heroes as described in the stories and monsters in stories aren't monsters as these stories describe.
Humans always say families are important and they should serve their homeland when they grow up so that the young generation would have a chance to grow up without seeing disasters at a young age.
