[Defiance]

Okay, so almost halfway through my reread of DG, just got to the part where Sormo, Nil, Nether, and Duiker enter the warren with the Jaghut ice where the Semk god is. Sormo says: The highest of Omtose Phellack, these rituals never die, Historian. They rise, subside, and rise yet again. Even now, one is born anew on a distant land, and those rivers of ice fill my dreams, for they are destined to create a vast upheaval, and death in numbers unimaginable.

So, the question is, who and where is Sormo talking about. I see two possibilities:

The first thing that came to mind was the Pannion Seer, as he was a Jaghut and the Pannion Domin did bring a lot of death. The other thing I thought of was the ritual failing in the icelands northeast of the Edur homeland; the ice is starting to melt in MT and causes some chaos in RG.

Dunno, I like your first idea okay, but it could also be a piece of land we know nothing much about yet.

[Bauchelain the Evil]

It could be both of those. However the second one happens millenias before the start of DHG. So I'd go with your first theory(although there are still problems timeline wise, which are, of course, not important )

[Jaghut Engine]

Could it be a metaphor reference to an ascending god ?...
The T'lan Imass could also fit the bill with respect to your first comment.

I think he is referring to the diminishing of the Jaghut ritual, the spear of ice, the rising water levels (and the financial crisis).

[Tatterdemalion]

This is bigger stretch, perhaps, from DOD...

Those Undead Ice Jaghut from DOD who save the KCCM?

[D'rek]

I'd go with the first - "born anew" matches that one far better than all the others mentioned which are more of a dying nature.
