[Genshin Impact] The Traveler's Unorthodox Way of Saving the World

The towering spire collapsed with a deafening crash. As the boy closed his eyes, the golden-braided boy stepped onto the continent of Teyvat with his sleeping sister. At the time, demons were running rampant and the people were suffering. "Saving the world doesn't mean you have to go in a straight line. There's a saying: take the winding road to save the country." Gazing at the chessboard, Aether smiled as he placed a piece. And so... From founding Khaenri'ah, to saving Golden-Winged King, helping Morax build Liyue, and planting a World Tree from beyond this world... "Aether, what is this?" Dainsleif stared in astonishment at the black tree glowing pink. Aether laid a hand on the trunk and smiled faintly. "This... is hope." Hope of saving everything. Hope that the people of Teyvat might see the true starry sky. As outsiders from beyond this world, Lumine and Paimon became traveling companions. While searching for her brother, Lumine journeyed through the seven nations. But for some reason, she felt that the people of this world were far too friendly toward her. "Traveler, would you like some apple cider?" The Anemo-colored bard smiled, trying to coax his old friend's sister. "Traveler, please consider Liyue your home. It will always be your place to return to." The retired Geo Archon gazed tenderly at the golden-haired girl, who was already Liyue's princess. "Miss Lumine, should you face any danger, just call for me. Xiao, the Three-Eyed Five-Manifestation Immortal, is here at your command to protect you!" The young adeptus kept a stern expression, though he was troubled inside. Why does the young lady insist on being so strong, just like her father? Her powers have been sealed. Surely she can call me whenever she needs me? "Miss Lumine, as your companion, I'm happy to help whenever you run into trouble. After all, I could never refuse any request of yours." The lowest-ranking Harbinger of the Fatui toyed with a protective charm, privately wondering when he could challenge the Traveler to another fight. So the teacher was right. Even with her powers sealed, Miss Lumine is the real fighter, compared to a brains guy like him. Lumine: ... Lumine: So there really is something wrong here, isn't there? PS1: The original belongs to MHY. The OOC is mine. PS2: Aether is the protagonist, not Lumine, not Lumine, not Lumine! Lumine doesn't appear until much later. PS3: Aether x Dainsleif, no fixed pairing roles. Zhongli x Tartaglia and Diluc x Kaeya appear later, with a little Kazuha x Scaramouche (Kazuha x Wanderer). PS4: The timeline begins 2,600 years ago, so there are lots of personal interpretations. The one thing I can promise is that it'll be sweet, sweet, sweet. Theme: An outsider saves the world? No, he's just saving himself.
