[Skyrim] Are the Ideal Masters more powerful than Akatosh? Seems the magic of the Soul Cairn > Dragonborn's ability to absorb Durnehvirr's soul upon victory over him.

Upon slaying Durnehvirr in combat, I'd have assumed that the Dragonborn would have absorbed his soul as per the usual Dragonborn action of absorbing dragon souls. Hell it should even be automatic, as the Dragonborn doesn't even realise they're different until defeating (and absorbing the soul of) Mirmulnir. 

But instead, Durnehvirr disappears, and reconstitutes outside the Boneyard as would be determined by the curse of the Ideal Masters. Does this prove that the Ideal Masters' curse is superior to Akatosh's divine gift/Dragonblood, and therefore the power of the Ideal Masters is beyond that of Akatosh?

I think it's a similar situation to Miraak's, who you also aren't able to eat. Durnibro's soul was already spoken for. 

Fun fact though, if you come at him before killing Mimjhrh3g5oj, he says he feels an urge to call you a fellow dragon though he can't explain it. He still names you Vanquisher in the end though.
