Genshin Impact: Starts with 12 Spells

In the vast universe. Chu Ge, as an ancient and powerful star god, his destiny is enough to make the stars tremble. However, he holds a secret in his heart - a world he has been looking for for a long time, Teyvat. One day, when the pioneering star god was exploring the endless void, he accidentally discovered a vague planet. This planet was the Teyvat that Chu Ge was looking for. After Chu Ge learned the news, in order to thank the Pioneer Star God for his help, Chu Ge agreed to Aha's condition, which was to prevent him from destroying the train for a period of time in exchange. When Chu Ge set foot on the land of Teyvat, he felt a familiar yet unfamiliar atmosphere. A vision of the future emerged from the depths of his memory: Teyvat would suffer a catastrophic destruction. In order to prevent this tragedy from happening, Chu Ge decided to take extreme measures to return Teyvat to the right track of the universe. He sealed his Star God's power and locked his memory in the deepest part of his soul. Then, he used the remaining power to transform himself into a complete Demon God of Teyvat.
