The aurora was supposed to be a good thing, but everyone in the higher dimensions that saw it didn't think that way. The Primeval dimension is the location Nivarna Realm is in the plane.
Other dimensions exist in the plane, and due to some unspeakable secret, they block the entrances to the other higher Dimensions but it is not perfect.
Their actions can be said to have some reason, as they also can't just enter and exit the Primeval dimension at will. Only this has not stopped some individuals from sneaking in other dimensions from the Primeval dimension.
It is impossible to cut off the path of those obsessed with the path.
The moment this aurora appeared, it reminded some individuals of their nightmares, as such they would not be able to sit still.
But that was not all as a golden lotus bloomed then the leaves spread out in the Primeval dimension before spreading outwards.
