Fiery Destroyer = Great Destroyer?

I mentioned this earlier on the PC Gamer article thread, but it got lost in the multitude of pages.
Anyway, doesn't the Fiery Destroyer who we will have to work with the dwarves to defeat sound a lot like the great destroyer from the Sorrow's Furnace quest Unspeakable, Unkownable

Quest dialogue
"The Stone Summit are dangerously close to uncovering the Tome of the Rubicon. Inside is the true name of the Great Destroyer, the bane of the living and nemesis of the Great Dwarf himself. If the seals that bind that book are dispelled and the true name spoken... well, let's just say there is no worse thing that could happen in this world.
I could use yer help gaining entry to Sorrow's Furnace and stopping the Summit from getting their hands on the Tome. Will you help me?"

Theories?

Great Destroyer = Ninja robot samurai Gwen that shoots lasers from her eyes and can morph into a herring to ensure extra devistation.

It's probably the same guy, especially that near the end of that synopsis I read here, he is referred to as the Great Destroyer, not Fiery Destroyer. Assuming that's not from the posting member but the article.

My guess is that it's a dragon or winged creature. Again, I remind you all of the Watchtower Coast. All those forts along the three great lakes were built to protect from a dangerous and long forgotten foe to the north.

Yes. The article you are pitted against the Great Destroyer of dwarven lore. What's confusing you?

the great destroyer and the fiery destroyer are probably the same being. it's also believed that the great destroyer is menzies and that the great dwarf is balthazar.

I read somwhere about caves under all the continents or somthing so what's stoping this "threat from the north" going underground and poping up in the shiverpeaks HURRR

The PC Gamer article mentions that the Dwarves call him The Great Destroyer while the Asura call him The Fiery Destroyer. Accourding to the article they are the same being.

The real question is WHAT is he? Menzies sounds like a resonable guess. The "Fiery" makes me think of the Titans. Could he be some kind of Titan leader? No longer under the control of Abbadon who knows what the remainig Titans would be up to? ....just a guess.
