Unicorns have similarities to Indian culture.
They practice meditation to focus their minds. Some believe in reincarnation. They have gurus like Starswirl who teach magical techniques.
I always thought they had this because I remember hearing somewhere how Greeks and Medieval Europeans thought there were unicorns from India who horn had special healing properties.
It would be interesting if unicorns were a Frenchlike culture with subtle Indian undertones.
I bet Saffron Massala comes from a group of unicorns who kept the old unicorn culture instead of changing like most in Canterlot.
