Asian includes everyone from the Philippines to the Aegean; from Russia to Sri Lanka. Asian fails to describe them. Should, anyway. In reality, we have the obviously ancient Japanese inspired cartography, architecture, and arms. That, and being the mysterious orient of Nirn.

The Tsaesci of Akavir were eaten by batw lore. The obvious, Japanese overtone is almost insulting.

I'm not seeing how any of that can be insulting to anyone?

Perhaps the Tsaeseci were simply Argnonians.

It's possible that some Tsaesci transformed into men as a result of eating them, which is my personal favorite theory.

In any case, the very concept of "eating" is important to them and will be the key to how they have humans in their ranks, one way or another.

Did the Tsaesci outpost in Oblivion have stairs / ramps or both? I forgot...

I was confused about this as well, so I just assumed that describing Akaviri as snakepeople was just used meteorically to describe their culture.

The one thing I want to know is, if anything in Mysterious Akivir is true; then how did the author learn all about Akivir while everyone else knows little to nothing about them?

Because it's a stupid copout.

If they ever appear in a game they will be humanoid anyway, just for engine reasons. Given that, I think the best thing to assume for now is that they are serpent looking humanoids and maybe normal humanoids as well, mixed together like on Tamriel.

I don't see how the engine would limit them to being humanoid. Oblivion had Spider-Daedra.

For some reason, I always saw word "Eat" with Tsaesci as that they vampirized the humans. It not just explains why they are also called a Vampire Race, but would also explain how men (possibly with some of snake features) can still be there tough they were "eaten".

Apparently you dont understand that they are no longer using the same engine as Oblivion. We have [censored]in dragons.

The engines are obviously the same, as anyone who has played Oblivion, Fallout 3, Fallout: New Vegas, and Skyrim would know. The problem is that people are arguing about things that are not engine limitations. All it takes is for a dedicated animator to do a serpentine creature properly and do the rigging for facial animations while talking. That's all that's required.

It isn't the same engine. Even if it's based off of Gamebryo, it is not the same engine.
