The information regarding the fact that the beastmen were the first ones to create a kingdom is already spread amongst their force, many races and groups were of course envious of this.
France and Russel wouldn't be able to create a kingdom under their rule because they are busy protecting the interest of their entire force.
Especially France, he was appointed by Shadowslash as the main commander of the entire army, the responsibility resting on his shoulder is extremely heavy.
The elves were disgruntled because the people of this world saw them as treasures or perfect slaves, when they heard that the beastmen managed to create a kingdom, they were only a little bit envious but more so happy when they heard this.
After all, as long as the beastmen educates their subjects quite well, they no longer need to hide themselves, they'll build a kingdom here but only after this world is finally be able to produce Mana naturally.
