The life of a Witcher is hard, a dark path, but for Aclehild is the only life she knows. Since she was a child, in the School of Viper, she has been a test subject in the most brutal physical and alchemical tests to obtein the total immunity to the adverse effects of potions and mutations.
She is the greatest triumph of her school’s arch-alchemist but she carried a only one side effect for that especial condition: the inability to feel again.
After all this, a Witcher emerged with a sharp heart, stocked with poisons and oils to kill any creature and target. The only thing that remains in her heart, since she was a child, is a stronge impulse to survive.
