As you say, we don't know much yet. And we most certainly don't know for sure what they are "half" of, so I think it's too early to say there will be a lore conflict. Some fans think they're half-demons rather than half-dragons, especially given the look of male au'ra.

I'm sure the Lore Team had thought about the potential scenarios and plotted the story accordingly. Its track record so far has been pretty good, after all.

In other words, please look forward to it!

(By the way, is it "au'ra" or "au ra"? I don't recall seeing an apostrophe in the official slides.)
