Danuser could say something completely benign like, “Yeah they are a completely different type of dragon, and come from proto-proto drakes” and people would tear him apart for it.
No one has torn him apart for saying that Sire D invented the Dreadlords. In fact, people love the Sire D stuff and the Dreadlord stuff. Although I honestly wonder if Afrasabi had come up with that idea and not Danuser.
I think you’re jumping way ahead. The expansion of Dragons all about Dragons hasn’t come out yet and there are multiple patches to look forward to.
