I'm not entirely convinced, it wouldn't make sense for Blizzard to create an entire language that none of the PCs would ever be able to understand or make sense of, it seems like it would have made more sense to just type random gibberish and simply slap [Draconian] in front of it rather than having it be an actually translatable language, at least at this point I'm pretty sure there's no other time when players are able to read it
