Good call on Silver King/Shiro. Completely makes sense now that he was kicked from the airship (cast off from the heavens so-to-speak) by the "possessed" person we thought was the Silver King after being possessed himself and murdering that Homura dude.

As for the mysterious creature itself, I'm still going with it being some type of Strain creature that is either out for some type of revenge against all of the kings, or has some other motive for doing what it is...perhaps it was the reason for the previous disaster? Like malevolence incarnate (opposite type of Strain compared to Neko maybe?)
