Well, they aren’t often wrong at EB but they are in this case. The people are referred to as Tatars as the term tartar was a misheard term from western Europeans, although they are western Europeans… Regardless, the reason I couldn’t find it was because I did CTRL+F and wrote tatars so it would be nice to have it spelt the same way throughout the system.
Thanks @neobahamut20 for catching that the spelling isn’t consistent with the game! I’ve passed this along to our web team so they can take a look.
