A History Of Teyvat: The Archon War 

A thing with the archon war in inazuma. We know that ei killed herself and let makoto be the archon. While archonhood, makoto made a new body for ei to inhabit. Then catalysm happened then makoto died and ei made scara and the shogun. Orobashi fled from the archon war to inazuma and hid himself in enkanomia and became their god. This is my personal theory, but in ei's teaser. We see her friends slowly dying, first was the tengu warrior who died due to orobashi which then in turn ei killing orobashi. In kokomi's words, ei killed him because he disturbing the peace in yashiori. Since we know ei is alive at that point, it was after the archon war since makoto already revived her. And if we continue the teaser. The oni got currupted by the catasym and kitsune saiguu died protecting inazuma from the catasym with other yokai. Then at the end of the catasym we see in the teaser makoto dissapearing next. Additionally, the other god in inazuma was the thunderbird which was also killed by ei.
