Mnemonic

Some ancient elders drove stakes into the earth, scratching deep boundary lines in the dirt. Everyone agreed: the land on this side of the grooves belongs to us, and that side to them. Each carved-out territory became a recognized region, defined by those marks in the soil.
Additional thoughts
Picture elders literally scratching lines into dirt—some on one side, some on the other. The earth itself holds the borders. Regions are earth that some people have claimed.
Quick recall
Some boundaries scratched into the earth create a region.
