Sakhi
Sakhi is a language spoken by feminists who had formerly been part of Thaoa. They had previously been a very aggressive military empire, at times the most aggressive on the planet, but when the Thaoan women realized that the tribes their soldiers were attacking were ruled entirely by women, they blocked their army and forced the soldiers back home. The women then signed a peace treaty called the Feminist Compact with their enemies, and abolished their own military.
Phonology
Sakhi was a northern dialect of Thaoa which early on gained vowel length and lost distinctive aspiration. The phonology of classical Thaoa had been (consonants only)
l j h k kʰ ŋ p pʰ m t tʰ n s x š b ž č ň ʔ
And in early Sakhi it was
l j h ġ k ŋ b p m d t n s x š ž č ň ʔ
The vowel system was unchanged, remaining
a e i o u y
Except for the new vowel length contrast.
