The Crio region, well-known for its harsh winters, should be the last game to be revealed. Dataminers continue to research the cold corners before the game's opening.
Many players assume the Krio region is north, and it is known that it extends beyond the Arctic Circle, and insiders confirmed these claims by revealing the position of Snezhnaya in Teyvat in the Genshin Impact.
Snezhnaya is at the top of the Anemo kingdom on the maps, according to Team China via Plusle. The port of Thorns, as well as the rest of the Anemo Archon's possessions, may be released already in December 2023.
Given that at the time of version 3.5, four out of seven regions were released, we can speculate on where the rest of the regions will be. Fontaine is known to be north of Sumeru and west of Mondstadt. Natlan, the Pyro Kingdom, is likely to be west or south of Sumeru, and Snowy, the coldest region, is to the north and possibly borders the Hydro country as well.
