I did not feel like stating every country in Asia with tigers, but you get the point right? (Tigers are not exclusively Chinese)
I'm guessing you are under the impression that Tang Mo is one region with one culture based on China and Indonesia, this is not so.
The Tang Mo Empire, has four regions, each with it's own culture and it's own monkey race.
About the weapons, "Chinese/Indonesian" does not mean one set of Tang Mo "hybrid" weapons, i can't even imagine what a Chinese/Indonesian hybrid weapon would look like... but i like the idea :lmao:
You can see our weapons in Corthians progress thread, it does not show everything he made, but they might include some pictures of Chinese weapons (a Jian & Dao i think) and some Indonesian weapons, Corthian did create a model of a kris (cris, creese, keris: a Malaysian knife or sometimes a sword, it is said to come from Java originally).
Obviously, those weapon models are not a hybrid at all.
By "Tascei", do you mean Tsaesci? And no, let's not give them Gothic plate armor
Crossbows is not a bad idea actually, and cannons are possible too, but not Dwemer cannons ofcourse =)
Dispite the very little official lore we have, it's safe to say Akavir is more or less Asian, Katana are from Akavir after all, and that makes it asian.
But the fact remains, there is not much lore to go on, so we can do whatever we like, it's like you said, "since Tamriel in the TES series seem to have anachronistic elements (ie. Roman segment & Gothic armors), I suppose there could be a mix of various elements for Akavir", so it's ok for us to mix things if we want to.
