Not really. All I got from Windel was that he didn't want to explain it, and KoL says I should change what Sonia's Portent does. I never actually got any information about what Sonia's portent actually told her.

My first instinct is to try and kill this monstrous thing, which I'm going to guess is what you guys what us to do. IC, Sonia isn't a shoot-first type of person, but since she doesn't have any information on this thing, all I can really do is ready an action.
