The Yehio are a sentient race native to the Erydai system. As the Yehio were beginning to embark on early stages of global industrialization, they were discovered by the Cyrva. The Cyrva felt a need to protect this developing species from the dangers of the universe, quickly disarming the Yehio and 'guiding' them peacefully, effectively turning them into a client state.

Disagreement on the Cyrva's part on whether this choice was ethical led to escalating tensions, and eventually to the outbreak of the Doctrine War, the first civil war in Cyrvan history. Consequently, this led to the militarization of Cyrva space and the formation of the Cyrva Star Armada.
