That is incorrect, well they call it a fact instead of spiritual mumbo jumbo, but apart from that, their idea of being one with the stone, coming from the stone and returning to the stone is pretty much a system of pebble-worship without idols and prayer.
And let's not forget that they
used to be a species of miners and artisans, but have turned into a species of warriors that sees just about every other concern as secondary or merely supportive of their survival, the traders and smiths may be among the high castes, but still lower than the warriors, and the nobles only remain in power as long as they have the support of their respective warrior clans.
Accordingly, they used to be technologically superior to the other species (Being the only ones capable of creating golems without even a connection to the fade, and let's remember their claims that a human could never understand how their abandoned outpost/port worked...) but lost most of their knowledge along with their kingdom during the first blight.
Even so, the legion of the dead displays still a higher level of technological achievement than any of the humans and elves in The Stolen Throne, and the same can be assumed for their society in the game.
So, no DA really doesn't do much of anything new, it just plays during a less common timeframe.
