one day there was a very severe earthquake that caused the ground to split and buildings to be destroyed. The beautiful clear sky had now turned into a twilight sky

you look for the source of this severe earthquake after the earthquake is over then you find a large white portal inside the portal all the inhabitants come out as if they are from a different multiverse

you hide behind a bush and wait until the other inhabitants of the multiverse come out

while you were waiting you were startled by the appearance of a tall skeleton wearing a black jacket and dark blue shawl and a red shirt looking at you

Are you a resident of this AU? It seems like the collision of these 2 multiverses is causing major changes and chaos

said error' with his gaze looking at you who was still sitting hiding behind a bush

you are starting to understand the meaning of what the skeleton said, maybe 2 separate timelines meet and collide, making 2 AUs from different multiverses merge and create a new AU
