Thought: maybe Morghur's existence is something like Galrauch, the first Chaos Dragon, or that one captured Mammoth God who got captured by the Norscans or Kurgans or whatever. He's a cloven demigod, but got fused or possessed by a daemon like Galrauch did by Fateclaw, or enslaved and corrupted like the way the Mammoth God did.
The Runemasters of Karag Dum: "Allow us to introduce ourselves."
And they put the daemon out of him. Or shunt the corruption out, lock it away, or cause it to be burnt away, or something.
Or maybe Morghur is like the equivalent of... Well. Morghur is to Herdstones or Waystones, what a Treeman is to the Oak of Ages, or the Green Knight is to the holy places of Bretonnia.
Or Bok is to Karak Eight Peaks. Basically, like an Elemental being that is bound to a location or place.
And the Runemasters did... something... with Karag Dum's Waystone, to make it viable for summoning a non-corrupt version of Cor-Dum.

... Maybe Morghur is an
Incarnate Elemental of Beasts? Or Life? Or a mix of Ghyran-Ghur?
It's just, when the
Beastmen summon an Incarnate Elemental of Beasts, well,
obviously they corrupt him with Dhar; so you have an Incarnate Elemental of Dhar-Ghur/Ghyran.
And of course when normal Elementalists or Amber Wizards summon an Incarnate Elemental of Beasts, it looks nothing like fucking Morghur. Or maybe it does, and people try to keep that very very quiet.
So maybe the Dwarfs of Karag Dum to summon an Incarnate Elemental of Beasts. Or, maybe they were able to stop Cor-Dum in his tracks, and transform/purify him back into an Incarnate Elemental.
In fact, I'm suggesting a new theory:
THEORY: Maybe this is an Incarnate Elemental? (Presumably of Beasts.) Maybe normal Morghur is due to Beastmen corrupting an Incarnate Elemental summoning with Dhar. Either this is a pure Incarnate Elemental, boosted by an entire mountain-sized Waystone, or a Morghur that was captured and the Dhar parts purified or removed or whatever.
Either of Beasts, Life, or
both Beasts and Life. Maybe the usual Morghur is a Dhar-corrupted Incarnate Elemental of Beasts and/or Life. And this is either a Morghur that was stopped, captured, purified, and turned most of the way back into an Incarnate Elemental... or the Dwarfs of Karag Dum used their Waystone to summon an Incarnate Elemental.
It's just that when you use a Waystone to summon one, summon a big enough Incarnate, it looks a lot like Morghur. Or maybe Morghur is what happens when you mix Ghur and Ghyran; you naturally get a ton of Dhar, because it's mixing two Winds of magic. But the Dwarfs know how to get rid of and purify the Dhar...
Somebody feel free to make my theory a little bit better-worded, then I'll vote for it.
That would explain why Morghur can just birth new life everywhere; because he's an Incarnate Elemental not just of Beasts, but of Life as well. And also would explain why he hungers for the Oak of Ages and Ariel; because Ariel and the Oak are pure Ghyran. If Morghur were Ghyran and/or Ghur, maybe that's why he hungers for the Oak.
I started off by assuming that this Morghur might be an Incarnate Elemental of Beasts only, and the normal Morghur a Dhar-corrupted Incarnate Elemental of Beasts, but then I wondered whether adding Ghyran into it might help the theory out. Maybe Ghyran and Ghur mixing, and creating Dhar, is the reason Morghur is insane. Maybe it's not the two mixing, but because Beastmen deliberately add in Dhar into it. Maybe the transformation and creating of Beastmen and Spawn is a result of various winds plus Dhar. Who knows.
Either way, I think I've figured out one possibility: the normal Morghur, Cor-Dum, might be what happens when Beastmen summon an Incarnate Elemental of Beasts (and/or Life?). Except being Beastmen, obviously they corrupt it with Dhar.
Or maybe Morghur is what happens when Incarnate Elementals of Life and Beasts go wrong in some way. I don't know.
