Did Freljord suffer from the magical and technological downgrade?

Looking at Lissandra, I see that her design is very futuristic, especially her helmet. But looking at Tryndamere, Sejuani and Ashe, I'm starting to think that these lands have suffered from a big step backwards. I'll tell you what does it remind me of. TES: Skyrim and nords. Many years ago, Ysgramor and his mighty people have built Skyrim with the power of telekinesis, moving giant stones by force of will. But at the 4 era (the moment when we have visited Skyrim) nords hate magic and stick with the brute strength and agility. http://static-3.nexusmods.com/15/mods/110/images/53581-1-1398784975.jpg As well as Ysgramor was an ancient hero, there were ancient heroes who have beaten Lissandra. Could it be that those heroes also had superior weapons and magic, compared to the more feral Tryndamere and company? And where did their heritage go?
