Shirren Names
These names tend to have palatal and velar consonants and they do not start with vowels. Though pronounciation guides aren't given, it's likely that consonant combinations are used as continuants, similar to Slavic languages.
When choosing names that start with a letter or letters, keep the prefixes short. One or two letters work best!
