If I were to make theories, I'm pretty sure it would take me years to think about the various outcomes this game will have. But there's one aspect about Teyvat that bothers me: how vast the world of Genshin Impact is. Technically, we refer to Teyvat as a continent, and even Zhongli, during his quest, mentions it is a continent. So, if Teyvat is a continent, there are regions beyond the seven nations, and we don't know how massive their scale will be. So far, with three launched areas in the game, we know how huge they are, and some of them are in the depths of the ground. I'm sure that as we progress through these nations, we will get to know more about Teyvat as a whole and delve into the areas that don't count as a part of Teyvat. Though a lot of people, including myself, refer to Teyvat as the world, in actuality, it is a continent. It's my hunch that down the line, after a few years, we will go through the unknown lands and explore them to seek the answers to the mysteries surrounding numerous events.
