If that's the shade of Khan's mana, could it be that the Nak intended for shade of Khan's mana to be 'feel inferior/ afraid' of Nak, hence compromising his ability to fight them?
I wonder if Chaos is actually a very powerful and noble mana quality that runs through the Nak. Maybe being Chaos' heir is like being the heir to the dynasty of the Nak and he just doesn't know it yet. Would explain the Nak saving him and maybe planting him on earth as a way to save their species
