In the history of the dragon empires, the dragons were never known to be unintentional expansionists.
The dragons hardly went out of their way to subjugate other races and if they did, it was usually temporary.
The only races that the dragons bothered to keep permanently were the few sub-races that came from them.
The wyrms, the wyverns, the drakes, and many more lesser cousins who were not affiliated with any laws could be said to be direct Vassals of the dragon empire.
Besides them, the dragons just never seemed to show any significant interest in expansion for no reason.
After they got their own heaven, they hardly had any reason to fight for resources in the mortalverse.
They were more focused on consolidating and developing themselves while maintaining some alliances.
Anyone who allied with the dragons could at least be confident that the dragons would not suddenly turn to stab them in the back unless it was absolutely necessary.
