Slaved Archmage
She was a child from a peaceful uncivilized village. When she was 11 years old, the kingdom they belonged to, burned their village to ashes, robbed their resources, raped the women, slaved the children and the elderly, and claimed the rich land as theirs.
To avoid being a victim of rape, at the start of the colony, the villagers forced her to live as a boy. As the only one gifted with noble intelligence, she had ideas unique from the general. She silently practiced magic and mastered the mana manipulation to appear she didn’t have a talent in magic.
Living as a slave, she faced thousands of difficulties daily for nine years. She was patient, taciturn and docile. Whatever her owner asked her to do, she did it, to live and realize her goal.
On her 20th coming of age, the owner sold her to a royal brothel for 100 crystals. In an environment where the painful memories reflected the past -- her resolution to avenge her family and the rest of the villagers, surfaced.
