Genshin Impact's first update of the Western new year hits on January 5th, 2022, and it's a pretty big one. Introducing the new Enkanomiya area, an ancient underwater island filled with dangerous enemies and constantly eroded by the Abyss. The center of the city is an artificial sun, and players will have to find a way to use it in the puzzles at the center of the island.
In addition to the new region, the Lantern Rite festival is back, with the chance to get a free four-star Liyue character. Additionally, this year's Lantern Festival will herald the return of the Jade Chamber, Liyue's extremely cool flying palace. On YouTube, you can find a roughly 40-minute video going over the whole 2.4 update. It's embedded below, too.
The two new characters showing up with the patch are Shenhe, a five-star character, who uses Cryo element polearm attacks to boost other Cryo teammates. The other, Yun Jin, uses Geo Vision, and buffs teammates' attacks and defense. Perhaps better, however, Yun Jin is an opera singer with a performance voiced by an actual artist from the Peking Opera.
