There isn't really much here to be honest.
It's a whole bunch of opossums who eat people, there's a sphere which is apparently their prisoner, and there are some vague whispers regarding a possible XK event. All in all it just feels like a series of loosely tied stories. I mean I really don't understand what connects these opossums to ancient prophesies of foretold destruction.
It just seems extremely forced. I mean it may have something to do with Powhatan mythology, but considering I'm not exactly a connoisseur in that field, the meaning behind this article is completely lost on me. Thus, my lack of enthusiasm towards your piece.
I dunno maybe this just isn't for me. ¯\_(ツ)_/¯
