Once Upon A God
Traveling parents were killed by giants. Kindly old dwarf found the baby and raised it as his own.
Motherless female halfling was picked on quite often by the other children in the dwarven community. Serenity spent a lot of time alone and angry. Da did what he could – taught her how to use an axe, how to work with stone, and how to use her anger against her opponents.
Then Da was also killed by giants. Serenity spent even more time alone, wandering the tunnels. Soon after, she met an unusual Drow Ranger and decided to accompany him to the surface world. She learned from him for a time, then struck out on her own.
