Trying to figure out the EU timeline / history

[Daedalus]

I like to think that the Frozen Horror was the very general that retreated with Zargon to the regions of Ice Mountain, north of the Sea of Claws. At some point hundreds of years ago the two must have separated so that Kelvinos was able to overthrow Mr. Ice. The world is a wide place, and the likes of Zargon, even weakened, aren't going to let it lie when other plans outside of the Empire can be sown.
