Natlan crew in Mondstadt Event

There's a new story based event in Genshin, seems to be centered around the Natlan crew (Varesa, Xilonen, etc...), but set in Mondstadt. Sort of an exchange program it feels. Not sure what exactly is the link between comics and the arena event that is being prepared though. It seems to have the usual mini games in each different stall and a main story divided into chapters. Seems like one of the mainline events for the patch.

Not sure the connection yet, but I guess they'll explain it further in the story. Time to keep reading.
