Well, I don't recall at any point it ever being stated that Skyrim was completely covered in ice and snow. And although it snows on the southern half (or close to half) of Solstheim, it's still reasonably live-able as far as fauna and wildlife go. The Netch are probably a stretch, but the Kwama could probably survive just fine, given they live primarily underground.
Netch and Kwama are blight-induced monstrusity native of Vardenfell, not mainland Morrowind
Just load Arena (TES1) to see what mainland Morrowind was like
In Arena, Vardenfell was only the location of the dugeon Dagoth Ur
In Morrowind x-pack Bloodmoon, Solstheim is like a mini-skyrim
-wolves-bears-sprigans-a single troll (udeyfrike) - a single frost giant (Karthag) - riekling (sort of blue falmers) - giant boars - draugr
the north is like skyrim northern coast, the south a bit more like solitude (milder)
the biggest difference is the presence of skaal tribes, which are a bit less civilized than nords
they like in houses that ressemble jorvaskr - but let's not forget at least 200 years passed since the morrowind story
**it's still reasonably live-able as far as fauna and wildlife go**
northern solstheim is really a glacier, so it's more like iceland or even groenland - a bit north-polish in the northern part
just rieklings up there
*even though it's on slightly larger than Cyrodil(In in-game scale).*
I tried measuring it. seems each hold is about 30 minutes across. so the whole thing is 3x the width of vardenfell, which is about right
not sure of the exact comparison with oblivion, I never measured it
I used a second technique, comparing screenshots from high peeks,
and comparing with the video done by someone who used the mod that remove the morrowind fog
he went flying slowly giving a peek from high up
because he went so slowly, I could compare things like fort size
again it showed skyrim to be 3x width 3x height, so that's 9x the surface
vardenfell also seem a lot less impressive with the fog removed, doesn't look like a volcano at all,
limitations of that era - it was not built to be seen without fog
*Skyrim in general feels massive because of it's extreme climate, even though it's on slightly larger than Cyrodil*
so no, it's probably a lot more massive than cyrodil !
I recal someone saying he measured it, and it was not much larger than morrowind's vardenfell
the only way you'll find skyrim small is by riding a horse 8D but that's cheating
*cut and paste enchanted forest
everywhere else. *
yep, and not verry enchanted compared to ... riften autumn forest style !!!
the wilderness in Skyrim is magnificient, and it's full of wildlife, including insects, fishes and sometime even birds
*know how the Netch and Kwama survive*
obviously that dlc will need a chunk of vardenfell as well, that's the only place they live in,
except maybe telvani islands, but I don't recall seing them there, it was all boat transportation arround the east coast
If you mean for armors (bonemold) they could do it with frostbite spiders
who knows ... maybe we miraculously get all of morrowind
maybe they're testing the technology for the remake of daggerfall ....
real procedural world ... and this would be the first test
but so far dlc were tiny, so I'm not getting my hopes up,
unless they did it on purpose because of the xbox360 exclusivity
