That's probably where I got mixed up. And yes, that is a bit interesting, it seems that there are constant fire and ice/cold comparisons to the Dwarves in Eye of the North.
Cold stone Dwarves vs fire stone Destroyers
in Sepluchre of Dragrimmar, near the anvil is lava next to the ice
What you stated
And there are others as well - I think.
-also note, the Hammer of the Great Dwarf is guarded by Cyndr and lots of fire elementals-
