Oh, I hadn’t even noticed that. One possibility is that one continent evolved faster than another. And that actually happened in our own world. Remember that China once had technology far more advanced than Europe’s. Many of the technologies we in the West credit to Europeans had already been used in China long before.how can we have some kingdom on the verge of discovering guns while another cant fucking make glass
Not to mention some quite curious cases, like cities of Indigenous peoples in the Americas that had very advanced sewage and paving systems, and even more advanced knowledge of astronomy than Europeans. Yet, for example, they hadn’t discovered the wheel. So, that could be the case here as well.
