Gliese 581

Gliese 581g is the name human astronomers have given to a "newly discovered" planet.

In truth, this planet's name is Kurodana, and it is home to a very humanoid race known as the Alio.

Unlike Earth, Kurodana is not in danger of being eradicated by World's End or The Alpha Conspiracy, as the Alio do not harm their planet in such a way.
