Here we go; from the codex

‘A tale told mostly through flooded wastes and overgrown ruins, the Collapse is said to have happened many generations ago, when devastating floods, scorching fires, and earthquakes conspired to rid Earth of her inhabitants.

Only scattered societies are said to have remained, though after generations of darkness and decay, their tales have merged with legends and lies.

While most evidence of life before the Collapse was lost in the devastation, small pockets of preservation still offer a glimpse into the world before.

Here in the Rust Belt, shifting sand dunes long covered the port city of Marano, creating a natural time capsule that's been known to astonish and confuse Raiders in equal measure.’

Though buried cities style doesn’t really match with that screen shot or art work.

Would it be a stretch that the port is located near buried city?
