The three great factions of the Milky Way ruled the three spiral arms respectively. The relationship between them was very subtle.
On the surface, because of the previous cross-spiral arm war, the Erehuana Military Treaty Alliance launched a powerful attack on the Declan Empire and fought with the Noctem Chamber of Commerce. Although they were finally forced back, it also caused an extremely strong conflict between the Erehuana Military Treaty Alliance and the other two factions. They even openly faced the enemy.
However, as the three super factions of the Milky Way, how could their relationship be so simple?
In fact, ever since the Milky Way stepped into the era of the Milky Way Civilization, after these three great factions were formed, they had always been involved with each other in history and had their own attacks and defenses. No matter which side was too powerful, the other two factions would join forces to suppress it.
