Exhacte was the native language of the Exoi people of Toriafas. As they founded and spread the Exoi Kritocracy, it became the official language of all the Kritocracy's worlds, though Minnisiat was a common second language among Exoi. The language had a written form, in which all the scriptures of Salbin were written.
Rin Sakaros "downloaded" Exhacte from an Exoi soldier upon her arrival on Toriafas in 155 ABY.
