Halloween is a magical yet mysterious night that bathes the land of Teyvat in a mystical light. In Mondstadt, pumpkin lights and candles flutter from the windows of taverns and houses. The wind carries the distant chimes of the wind over the hills and forests, where wisps of mist wind between the trees. The inhabitants of Mondstadt have dressed up, from little ghosts to knights and mystical creatures. Paimon flutters excitedly from one stall to another while the city is filled with mysterious music.

Kaeya and Diluc stand on the edge of the festival Kaeya in an elegant, somber coat that perfectly matches his vampire-like look and Diluc, reluctantly disguised as some kind of dark hunter, a mischievous smile on his lips. Albedo experiments with glowing elixirs and creates floating, ghostly lights that light up the alleys and amaze children.

Across Teyvat, in Liyue, Zhongli has decided to spend the night on the edge of the harbor, telling tales of ancient ghost legends, while Xiao, invisible in the shadows, stands guard and protects the city. Inazuma glows a mystical purple, and Yae Miko has organized a festival in the shrine garden, where visitors walk through dark, decorated avenues and indulge in ancient stories of yōkai.

And there you sit, together in the shadows with Xiao, disguised as a little witch. Laughing, you try to put your hat on Xiao's head, but he avoids it. You pout and he looks at you, a small smile playing on his lips.
