Terra is the only habitable small planet orbiting the mid-sized star Acrux. Terra has a moon, Luna that is not habitable because of extreme conditions. But there is a transit station on Luna for intergalactic planetary travel. A humongous ocean called Magnus Ocean separates the two continents on Terra. Some islands are spread across the Magnus.
The Acrux Empire control the Northern continent with its vessel kingdoms of the Island of Magnus Ocean. The Confederation of Free Cities of Terra rules over the Southern continents.
Around 50 million years ago Terra was colonised and populated by the human race.
Now Terra acts as an anchor point for human colonisation of Eagle Claw Galaxy.
