The Elder Scrolls XVI: Sworn to Carry Your Burdens

[veti]

It's a Kirkbride post, and thus dubiously canonical, but the Seven Fights of the Aldudagga shows Alduin eating a previous world, and it does at least in part involve physically eating the land.

I... would be comfortable with chalking that up as allegory or metaphor, rather than imagining Alduin literally sneezing out farmsteads.
