Rator III was a Romulan world.
In 2388, after the destruction of Romulus, the leaders of Rator III attempted to proclaim themselves the new capital of the Romulan Star Empire (and the planet's leadership council calling themselves the new Romulan Senate). Other worlds made similar claims, challenging the leaders of Rator III.
2391 saw Rator III become the first planet whose people claimed Admiral Taris to be the Romulan leader, after a military victory of Taris's in the Zeta Pictoris system. The admiral attempted to convince Romulan colony world leaders to come to Rator III in order to build a new government and capital.
