Sounds better than my theory.

I think the soul king used to be in sereitei, but he has powers like Yhwach and absorbs a majority of the energy of souls he stabilizes across the "universe" in other words he gains a little bit of power whenever anything dies and moves between soul society and back. I think a soul of a person who is reincarnated should be made blank again right? leaving just the foundations otherwise people will have the same recurring soul. So when their soul is wiped clean to be recycled this adds to the SK's power.

He used to live in Soul Society but may have become so powerful it started harming souls and damaging them so he had the Shinigami split apart his power, and seal himself in another dimension so as to not cause damage to the souls he has to recycle where he used to reside or something.

I think the Royal Guard serve the soul king, the title of it not the identity, so they now serve Yhwach. So I think they'll fight the gotei and pals soon enough. I've always thought the Soul King may have some ulterior motive otherwise he would have killed Yhwach the moment he was born.

You'd think the SK's power would be benevolent, but when Yhwach absorbed it, it seemed far more malevolent and "black" than I thought it would have been. It's weird. Somethings up, cool theory.
