I'm currently writing a book that does not take place on our earth, but one that I whipped up with different countries, races and whatnot, however, I'm having trouble describing a characters accent. With two other characters that come from a Scotland or Ireland type of area I describe them as having a Brogue, which is common when speaking of that type of accent. My issue is I have no idea how to describe a Russian or African accent without outright saying "Russian" or "African" accent, as it would take away the immersion in my opinion. Or even an accent similar to Ragnar from the Vikings series. Any words or methods I could use?
