So... I just have to wonder, why doesn't she just ask the spirits not to help the humans for awhile? Humanity in that world relies heavily on the spirits, so it's obvious their military might relies on them as well. The spirits will literally do whatever she wants, and it'll force the humans to retreat, thus reducing the casualties on both sides.
@Turkeysocks Now that would be too easy. She's also the person who thought her dumbass "friend" would actually listen to the warning she gave her after visiting instead of making things worse even after years of dealing with her bullshit. I'm not expecting good decision making from her anymore.
