The Twin Star wasn't much smaller than the Demigod Tribe's Divine Origin Planet. The reason behind its name was a mountain.
One of the highest mountains in the entire Divine Union.
With a height of 36,000 feet, these were the tallest twin peaks on the Supreme Twin Star. Anyone that saw this huge mountain would sense its unparalleled status. Thus, it was called the Supreme Twin Star.
The Supreme Twin Star had originally been a territory of a small sub-race of the Demigod Tribe. However, they had since moved out of it due to the impending battle.
Therefore, there were no longer any intelligent living things on the Supreme Twin Star.
There was a smaller planet about three million miles away from the Supreme Twin Star. This was the Supreme Twin Star's satellite, so almost all of the spectators had gathered on it.
