It is a very uninspired choice to make the King a more capable military commander than the Elf who has fought for at least 120 years as an officer. But she is a woman, I guess. And this is a Japan insert.
Gustav was also a veteran, wasn’t he?
Dineru said he started building the country after the battle where she also fought.
Okay so elfs are not born and the orks only have a baby every 10 years. Man war would kill them off in the long run. Like humans and other races would just out breed them in a war.
The orcs would celebrate if they could have even a single baby born in a decade
They maintain their population because they’re so damn hard to kill.
But in addition to their long age, there’s their glutton, so nature probably made the choice to keep balance.
