In my new story, Citizen Weevil as you've seen, I have primarily based the Changelings and their culture off Japan. However, I was mulling over a new idea to throw into it. Like there are different races of pony, what about the concept of different races of Changeling.
The changelings we constantly see in the show I see as being the Unicorn equivalent of Changelings, due to their horns. So I was thinking, as this story tackles race relations, I should include the Earth and Pegasus equivalents, so I can discuss their own inter-race relations and cultures.
Here's what I was thinking:
Hornet/Unicorn Changelings - the Changelings we see in the show - their culture is based off the Japan.
Beetle/Earth Changelings - their culture is based of China.
Moth/Pegasus Changeling - their culture is based of Korea.
In this regard, the way I'm writing the Changelings is based, albeit loosely, on different Asian cultures. If you have anything you wanna add or suggest changing, as I'm open to that at the moment, feel free.
