In the lore of The Elder Scrolls V, the Snow Elves have been driven underground by the Nords. But the in-game legends about the mystical race make it sound like they’re former badarses who’ve been laid low and are ripe for revenge.

Bethesda’s already on record as saying that DLC for Skyrim will be rolling out in the style of expansion packs and these files certainly make it seem like that plan will be going into effect."

cool

I'm on my second play through (blood on the ice wouldn't work) and I have found a million and one quests I missed the first time. Dwemer ruins are my favourite place to explore atm, especially with all of the texture mods I've added, the Falmer look sweet.

Yay can't wait for the expansion! Though I think I was a bit more hooked on Oblivion than I have been on Skyrim

Sounds great, hopefully it won't be too much of a breeze for higher levels because that would be a bit disappointing :)
