[Genshin Impact] Teyvat, but Building Interstellar Relations

After an encounter with the Aeon of Elation, the Astral Express Crew accidentally arrived in Teyvat. Once they learned about the plight of this sealed-off land, they decided to save it and bring it new hope: establish relations with the universe! The Stellaron-powered social butterfly called in a Memokeeper director to make a movie. Thanks to a massive publicity campaign, this miraculous land, which had been closed off for so long, was quickly exposed to all the major powers in the universe. Take the Geo Archon of Liyue, for example. He could turn stone into gold and had fought for years to protect a corner of the mortal world. That golden power of divine rock, which symbolized protection, looked awfully familiar! The IPC: Nothing more to say! He's definitely one of our Amber Lord's missing, kidnapped Emanators! The Geo Archon: ...By common sense, well...never mind. Some scholars discovered that this sealed-off planet contained a place called Sumeru, which still possessed plenty of advanced technologies, such as dream communication, that could only be invented by Genius Society-level geniuses. They say the place is full of talented people... Students in one of its schools have to learn at least twenty languages just to meet the minimum graduation requirements! The scholars: Good grief... What kind of sacred place has Nous's gaze upon it?! It must be hiding an Emanator of Erudition! Lesser Lord Kusanali: ...Well...if you say so... The people of the universe saw that Fontaine's dragon king, Neuvillette, held authority over water and could command all the water dragons. He could transform into a dragon or keep his human form, and could even maintain a thousand-year lifespan and reincarnate better than the Xianzhou's Vidyadhara elders. There's no arguing with this one. No one can question that he's one of the descendants of the Aeon of Permanence! The Vidyadhara elders: Oh my goodness! This surviving descendant of Permanence is so impressive! We didn't lose him, but he looks like just the right kind of talent to kidnap and make a Vidyadhara elder! Neuvillette: ... That's too much. I'm beating them up! Because of certain unknown, unusual properties of this continent, it attracted all sorts of factions: Galaxy Rangers, Knights of Beauty, and even the IPC, the Intelligentsia Guild, the Xianzhou Alliance, and more. After the powers of the universe moved in, Teyvat connected with the cosmos, and its overall appearance underwent a sweeping transformation. Hot lamb milk, cosmic bubble tea, mobile internet, idols, and more became part of the daily lives of the continent's residents. Many people also ventured beyond Teyvat. Yun Jin, Barbara, Furina, and others formed a group and debuted as hugely popular cosmic idols, touring nonstop. After learning how vast the sea of stars was, the Adventurers' Guild quickly joined the Trailblaze faction, hopped aboard their newly built train, and became a new breed of cosmic wanderers! When the Heavenly Principles awoke one day, they discovered that the world had changed. Wait...what the heck is the IPC? Why are there so many stowaways here?! And...why have the Geo Archon, the Anemo Archon, and the others under my command become your Emanators?! You can't just snatch people like that! Hold on...why has an Aeon come to my doorstep? Don't come any closer!! 1. Teyvat's setting in this story has been changed a lot! It will be heavily adapted to the Honkai: Star Rail universe. If anything differs from the Genshin Impact game, it's been changed here. 2. The author is an Imperial Lord fan. Well...you know what I mean (covers face). 3. The details of interstellar diplomacy, national responses, idol debuts, and so on may not be very rigorous, since the author isn't an expert on those topics. I'll write whatever seems fun... If you're okay with that, come on in. If not, please stop here! 4. The timeline in Teyvat is roughly just after the Traveler finished Fontaine, before setting off for Natlan. There may be mistakes in the story, like characters having met during an event, which the author might accidentally misremember. Please go easy on me qwq~ Theme: The path of exploration never ends
