Today, Galar's topography is among the world's flattest, and when one looks outside in the distance the tallest thing they see is likely to be a tree, skyscraper, or dynamaxed pokemon. Yet the geologic record shows that this was not always the case. Long before human habitation, Galar had high mountains; it does not today because the Drednaw ate them.

Drednaw metabolism is slow – on a timescale of months if not years – and unlike Snorlax, it is rare for their appetites to prove a problem within a trainer's lifetime. Even when exposed to Dynamax energy for the length of a battle or tournament, Drednaw will typically be renourished by a feast of easily affordable stones, and today are rarely if ever found digging into the bedrock for food. But the nests of the contemporary Wild Area release a small fraction of the Gigantamax energy of prehistoric times. Mount Galar once towered as high as Coronet and was visible from as far as Kalos, but the enormous pokemon on its slopes scared off any invasive species – save perhaps for one.

It is not known where the semi-aquatic Drednaw originated, whether it developed in Galar as a local variation of a species like Blastoise or swam there from across the ocean, too confident or lazy to be scared off by the local dynamax pokemon. All agree, however, that it must have been a terror in its Gigantamax form – and that the grass pokemon which might have stopped it were too entranced by the prospect of more nutritious soil underneath. It took millions of years to build the peaks of old Galar, which radiated endless dynamax energy, yet only a century or so to devour them; today, only scientists and elderly Drednaw remember they ever even existed.
