Minerva's past is unknown, but she apparently left her home to go adventuring, having lost all meaning in life. During her travels, she became an expert knife fighter and became a mercenary until she settled with Esther's tribe. When she's not travelling and selling her services as a mercenary, she serves as Esther's chaperon, teacher and mother figure. She's well respected in the tribe for her vast knowledge, strength and charisma. She is accompanied by an ostrich companion.
