Inconsistencies with the sundering (Spoilers)

[Iscah]

If the cutscene wasn't an allegory/metaphorical, then what's your answer to Hytholdeus walking calmly past a giant man-eating monster with neither of them caring about each other? Did Venat also literally walk down a smoky hallway covered in blood while seeing shades of sad and angry people?

I don't think the question is whether it's an allegory. It clearly is.

The problem is seeing where in that allegory you're supposed to see the allegorical outline of an epic fight between Hydaelyn and Zodiark, given that Venat seems to engage in sundering the world for purely philosophical reasons and not in battle.

There was an event where a person got killed by a monster. There was an event where Hythlodaeus farewelled Hades. They didn't happen at the same time but we see them overlapping.

By that assumption, the argument between Venat and the Zodiark worshippers also happened, but perhaps not in that time and place.

Where then is the room for the clash of primals? When do we shift from overlapping "real" events to pure metaphor? We clearly have by the time of Hydaelyn's "final walk", but that seems different to what came before.
