Vexia

You may be looking for the old universe counterpart of Ib.

Vexia was a country founded on Earth in Millennium 2. It survived until Millennium 10, and then created a colony on Urness, which was named uR-38-4 at the time.

After its mainland on Earth was captured, and it was destroyed in the War of uR-38, it waited for the radiation to dissipate, and then re-established itself, quickly becoming the most powerful country on the planet.

When the Earthlings attempted to colonize the planet, Vexia managed to keep its territory, and created an alliance with other Urnians to defend themselves.
