Which race deserves to be the main protagonist?

News for you people.

There were black and brown people all over medieval Europe.

If the fact that both the Roman Empire and the Crusades displaced massive amounts of ethnic demographics throughout their respective time periods (to say nothing of the Mongol Empire, which makes those other two look like baby stuff but was still Asia), and the evidence that they've found in viking warrior burials that there were ancient Norse who practiced Islam (among other things), and that in terms of folklore, there was a Knight of the Round Table who was explicitly black surprises you, consider this, which will blow your mind:

People travel.

People communicate.

People pay lots of money for stuff that's hard to get locally.

This is true today, and has been true since the dawn of human history.
