This is loosely based on the idea – fairly common among Hetalia fanfictions – of a school for states, counties, and other regions. I've read a couple of those, and started thinking about how the more obscure regions might interact, particularly those around where I live, including the areas in to the north of Adelaide, which seem to idolise Cornwall and all things Cornish, but which – to my knowledge – have little to no actual contact with Cornwall.
I don't own Hetalia or any of the lands or regions depicted. I don't even own any land full stop! Any resemblance to real persons is coincidental. Any resemblance to real places is strictly intentional.
"Kernow!"
"Kernow!"
Devon looked on in amusement as two small blurs ran up to wrap their arms over his more westerly twin. "You have admirers, Cornwall."
"Ugh, gettoff," Cornwall muttered, trying to detach the two. "Who are you?"
"Boss 'm Kernow Bichan!" the first, a little girl in a floral dress, white pinnie, and a crown of flowers on her head of messy blonde curls, beamed at him.
"Boss 'm Map Kernow!" the second, a swarthy lad in trousers, a sturdy jacket with rolled-up sleeves, and a flat-cap, his face liberally smeared with dust, added happily.
Devon's smile turned to laughter. "You have children, Cornwall?" he asked breathlessly.
"No!" Cornwall exclaimed. "Um... I don't know. Maybe?"
"Mid-North! Copper Coast! What did I tell you about running off?"
The two teen-looking lads turned around at the shout, spoken in an accent that didn't seem quite Australian, and saw a teenage girl dressed in what seemed very much to be hippy attire, paint-splashes on her clothes. She was trailed by another a small group of similar-looking youngsters, as well as a teen Aboriginal boy.
"Look, it's Kernow!" the little girl beamed, running over to grab the older girl's hand.
"Yeah, we found Kernow," the boy echoed.
"You're Cornwall?" the older girl asked in surprise. "Who's he?"
"I'm Devon," Devon held out is hand. "And who might you be?"
"I'm Adelaide," the older girl shook his hand firmly. "Sorry about the pastoral regions. We won't bother you again."
"But, Ad-lay," Kernow Bichan – or was it Mid-North? Or Copper Coast? – whined. "It's Kernow!"
"Yes, yes, you can bother your father later," Adelaide told her. "Come on. Sydney's running out of patience with us. Perth is beginning to talk about succession again. See you later, Cornwall. Devon."
With that, she led the entourage away.
Devon turned to his brother. "What just happened?" he asked.
"Kernow Bichan" is the Copper Coast, probably the whole Yorke Peninsula and possibly the Eyre Peninsula as well. The Copper Coast is pretty much the centre of Cornish culture in Australia and has the largest Cornish festival in the world, Kernowek Lowender. Kernow Bichan's appearance comes from the maypole and furry dancers (local schoolgirls) and their costumes during Kernowek Lowender.
"Map Kernow" is the Mid-North Region, which includes major Cornish/copper districts such as Kapunda and Burra. Kapunda is perhaps best known for its seven-metre stature of a Cornish miner, called the "Map Kernow (Son of Cornwall) Statue".
