Paying The Price To Become Krishn World's Lord
This, of course, wasn't accepted in the political big circle of these two races. As that would mean a common dude from a weak race would inherit the throne of their two mighty races.
In other words, the weakest race would be in control over the two big and mightier races. So the higher ups of these two races decided to wage war, wipe out the weakest race off the planet!
But that came at a hefty price to pay! After all, weapons of mass destruction weren't just a sole trait of foolishness of humans. Even if that race was the weakest, they still got weapons of mass destruction.
