You know, another idea occurred to me. Maybe my homeland wiped ITSELF out. (They zombie apocalypsed themselves or something, I dunno.) The Sky Kingdom tries to contain the situation at around the same time my faction returns from being somewhere else. It then looks like the Kingdom destroyed their homeland, and I doubt they would be willing to entertain any other explanations.

In retrospect after having written that stuff, that may be making it overly complicated.
