It's really unfortunate, I never see people talking about TES Travels games in lore discussions. I can't find much information about Dawnstar or Stormhold. I don't think we even have confirmed time periods, and no one's bothered to deduce them either. But these "Ice Tribes" and "Crystals" stick out to me as lore-bait. Shadowkey, http://www.imperial-library.info/content/elder-scrolls-travels-shadowkey, is the most interesting. It has this concept of "http://www.uesp.net/wiki/Lore:Shadow_Magic". It's unfortunate that no one, not even Bethesda, has been referencing these games. I'm interested to see how the community reacts to the lore from these games
