I've never imagined it being written by a Tang Mo, since the language used implies being written by someone who isn't Akaviri:
It's been a long time since I've read it, and I hadn't noticed that, so I'll grant you that. Which does beg the interesting question of who exactly wrote it, as the writer seems intimately familiar with the land and its politics. I'm also not the first to attribute Mysterious Akavir to an Akaviri. It's a theory that is often combined with the "eating means cultural eating" thing, something that was supposedly brought about by a mistranslation by the Tamrielians (Tam Raelians? That's a scary thought). Which is a nice idea, even if wrong.
Plus it contradicts itself:
The first paragraph states that they literally ate the men of Akavir. Yet the latter implies that to eat means to enslave.
No, the latter implies that they enslaved the dragons, possbly for the purposes of eating them. And they were used as warmounts, after all. But I think Michael has confirmed that eating means eating.
And then there's the most ridiculous bit:
Now how exactly did this writer manage an interview with Tosh Raka?
It might not be an interview so much as a summation of belief. Note that it's written in the present tense:
"First," Tosh Raka says, "is that we kill all the vampire snakes." Then the Tiger-Dragon Emperor wants to invade Tamriel."First," Tiber Septim says, "I want to conquer Hammerfall." Then he wants to move on to Morrowind.
Since when have aspects of Akatosh taken on jumbled versions of his name anyway?
It's not so different as Tiber Septim claiming to be an Atmoran despite the fact that the flow of Atmoran immigrants stopped thousands of years ago. Or - and this is related to the previous point - claiming Ysmir to be "the Nordic aspect of Talos". Mantling requires one to take roles in order to gain power, and taking a name of power and personalising it would certainly help. It's very similar to the way some western mystery traditions and magickal practices use drama as a means to invoke gods into themselves. Which is a hella fun way to do it.
Well, perhaps they thought putting it in two different sentences and using different words would be self-explanatory...
You got it.
