Ah ha... I'm not really sure despite being the one to help keep it below threshold. Lady Yae might have answers, though, if she has some time to spare. [ true to any fox youkai, Ajax tells lies in the most casual and using ways. ]

My guess, though, is someone or someones is tampering with things they shouldn't, like the lingerings of fallen gods. I can only imagine the current state of Inazuma's people helps feed that remnant miasma from the hate and suffering under the shogun's iron fist if not one of her own. There are not so many vision bearers, but there are far more poor people in the countryside left to fend for themselves in addition to the rebels.
