Is the database used different for each country?(Easter,Western)

First off, I live in Korea (not up north), and while today is my first time using Firefly, I'm not new to AI illustration programs.

I'm trying to make new Firefly Image based on this image that i made from Midjourney about few month ago.

This is the prompts to make that image in Midjorney, and the important part is 'medieval man'.

I tried to make new illust like that image, just a medieval man walking over a dirt road.

After few fail of poor stuffs, I realized something is basically wrong.

Does that looks like 'Medieval' outfit?

Does that white, blue colors are with in 'Medieval' theme?

So I experimented with creating a "medieval" themed image.

REALLY?

Where the hell is medieval theme images?

Do you think this really fits the keyword "Medieval"?

As an Easterner, I don't think it really fits the keyword "Medieval".

All same results output even I entered US version of Firefly website.

I am deeply saddened by this.

Is there any way out of this disappointing outcome?

Or is anyone else (in the western world) typing this prompt and getting the same result as me?
