The thunder monsters wanted to know who Adam's ally was, but they didn't dare disobey Marhen. After all, if Bathild weren't their leader, Marhen would surely take her place.
No, that's not even true.
In most cases, it was Marhen who acted as the leader and commander, while Bathild played the role of their strongest fighter.
However, any sufficiently intelligent and wise person could lead the monsters and rule the territory, but not everyone had the chance to become a Lord and gain the power to protect other monsters like themselves.
Marhen was a Lesser Elder, he had only one step left to evolve and become an Elder, but Marhen had been at that level for quite a long time. She had only two steps left to become a Baron.
If she killed Adam and Fromund, she would get the Twilight Crystal and surely become a High Elder.
