To me this card sounds more like the Collapse than the Red War. Think about it. We see from the trailers that nobody knew the Cabal were coming. And by the time we knew they were here, they had descended upon the City already. There would be no possibility of aerial escape, much less getting out of the atmosphere. We scattered remember? We are the Last of Humanity and we are centralised in one City. We don't have the kind of fleet to evacuate Earth against a force like the Cabal on such immediate notice. That's why we run into the EDZ. Closest place to seek refuge and launch a counter to get our home back. The simile of the flower is used to describe a ship; how it explodes into flames. I would not think that the Cabal would use a combustible shield to capture the Traveler. Considering during the Golden Age, we spread out through the system, I would imagine that the imagery on Jupiter is also about the Collapse.
