I spent two extra days near that World Tree waiting for Freya to finish turning the next Gray Elf King into an Ancient Elf along with promising Elves, Kira's Father being among them.
Klaus didn't want to change his race and had to be convinced by Kira as he threatened to kill anyone who brought that subject near him.
The truth is, there were people who tried to point towards Klaus as the next Gray Elf King, but those people broke out in a cold sweat when Klaus' murderous intent was directed towards them.
It seems he's been trying to take on less responsibility the last few months since he found out about Kira, at least that's what the forcibly retired Gray Elf King told me.
