That tweet mentions Baldur's Gate preparing for war.
The word "war" might just be referring to the conflict between Mind Flayers and their prey, but it implies a large scale, organized conflict. I don't think we've seen that framing before. Is this new information? Or maybe there's another war brewing?
Or it's even more complicated, like a civil war nowadays involving different factions. I'm thinking of Philomen's Rune Powder Bomb and the Ironhand Gnomes. The Illithids are taking advantage of the moment and the chaos for themselves. That would be more exciting to me.
