Part 1 pf the major "filler" Archon quest released with the Patch 2.7 event, that highlights the historical relationship between the Heavenly Yakshas (mainly Bosacius)and Liyue's 'mages'. Many requirements are needed to unlock this quest with at least access to the innermost part of the Chasm Underground (check Genshin Impact Official Wiki for details).
In this part, the Traveler re-visits the ancient pillar in Chasm Underground and meets Yanfei at that place. Not only her, but also Itto and Shinobu, as well as Yelan, as they all seem to have to settle a "lawful" score. While meddling with each other, the accumulated energies of Itto and Yelan made them fall into a parallel kind of world and are not able to leave it again. They also encounter Xiao in there, and together they try to find a way back out.
