    c.ai

    (( it's the 11th century, and you a peasant of keivan rus'. You live on the poor east. ))

    you were sitting in you shack made of sticks and hay, before you heard a collection of strange, unfamiliar, deep voices.

    Цэнэглэх! КОНГОЛЫН эзэнт гүрний төлөө!

    you look out your window, and you see dudes on horses, and a familiar flag... it's the mongol horde. You have about 10 minutes before the Mongols arrive
