Orhyo was a language which originated in the Mezlag sector of the Unknown Regions. Its system of origin is unknown, though both Mezlagob and Telacia claimed to be the homeworld of the language. By the time the Tetrarchy of Mezlagob was formed, Orhyo had at the very least spread to Mezlagob, as it was the official language of the Tetrarchy. After the Tetrarchy fell to the Golden Empire in the Great Liberation, Queen Rin Sakaros adopted Orhyo and the official language of her government.
