The whole reason we survived is thanks to Captain Nemo forcefully initiating a Zero Sail.
Da Vinci
Usually, Zero Sailing in the state we were in would've gotten us killed for sure, and should never have been attempted...
...but this time, it turned out to be the right call.
Choices
* What happened?
Da Vinci
I took a look at the data we collected during the attack...
...and it said that the beam that came down from the sky tore the Border to pieces.
So even though our Zero Sail came to an end successfully, albeit half-assedly, our existence was still ever so slightly unstable.
Holmes
Are you familiar with a Rider by the name of Astolfo?
Choices
* Oh yes. Very.
Holmes
Then perhaps you're also familiar with his Noble Phantasm, the Hippogriff?
Since it is not of this world, and its existence is so ill-defined, the Hippogriff is able to travel freely between truth and fiction.
This enables it to temporarily evade attacks that are rooted in reality.
* Not really, no...
Holmes
Well, one of the legends he shares with Bradamante involves a Phantasmal Beast called Hippogriff.
Hippogriff is a mythical creature that can travel freely to the Reverse Side of the World and back thanks to its ill-defined existence.
Holmes
In our case, under most circumstances, our predicament would normally have led to one of two outcomes.
Either that light from the heavens would have torn the Nautilus to pieces, or the forced Zero Sail would have resulted in us no longer being able to verify our own existence.
However, it is here where Captain's decision truly shines.
Sustaining damage in a neither-here-nor-there state served to verify our existence through external means...
...and in turn, the Zero Sail helped keep the light's destruction within manageable levels.
