The current Asgardians were made from an union of two races. Odin is King of the Aseir, and Freyja is Queen of the Vanir. The two groups had been enemies for a long time, before either Odin or Freyja were born. Odin insisted the way to end the war was for him to marry Freyja, and merge the two groups together to make Asgard. He and Freyjya have kids together. The Aseir/Vanir heirs ended the Aseir/Vanir conflict.
So after the terrigen cloud is destroyed (Inhumans don't need it to activate new Inhumans, that can be done under controlled circumstances, plus it kills some humans and causes dangerous mutations in some Inhumans) why not have the mutant and Inhuman leadership marry each other? Storm and Black Bolt could get married and have a child together. Magneto and Medusa could get married and have a child together.
Thoughts?
