This year's update, how can I meet the crocodile tribe? I'm Thai, so I don't really understand the language.
Wow, I didn't know that was a thing :o although you should still consider learning it because it's extremely useful and the process is enjoyable too compared to other languages. With knowing english, there are so many things world-wide you could explore, even through the internet, like webtoons, games, videos, movies, series, books... it also gives you a chance to learn other stuffs. The next thing you will see is how open the world became in front of you- just like a book.
As a native speaker of English I question the statement "the process is enjoyable compared to other languages". English has zillions of irregular conjugations and the spelling is a shambles. I'll give you useful, though. It's pretty much the lingua franca of the Internet.
To meet the crocodile tribe you need to travel to the Dwarven capital with ... bartender Dwarf whose name I can't recall. The guy who tends bar by the mines. Once you've traveled to the capital with him you should be able to retrace the route to find the desert. Exploring the desert you have a chance to find crocodile town.
