Genshin Impact 'Yakshas: The Guardian Adepti' story teaser released

Alatus is the Golden-Winged King who is also the Conqueror of Demons. None knows whence he came, nor whither he went.
Only at springtime, during the offering of lanterns at night, might the people see the glow at Guyun and declare: "Behold, the Vigilant Yaksha ends the dominion of daemons!"
Or they might hear the sound of a flute amongst the marsh reeds, but find none who play the flute, and thus declare: "Hark, the yaksha calls to summon his old friends to their homeland."
