Lily of Alchemy has been learning medicine since she was young, hoping to save the wounded. But for zombies, death might be their only solution. Lily of Alchemy learned the ancient art of potion-making from Old Man Josslehoof, who taught her the exact ingredients for the perfect, top secret anti-Zombie chemicals in her potions. Old Man Josslehoof also lives in a sewer and frequently combats giant dwarf overlords, according to Lily. What a guy.
