The elven citizens on the Ereinrith city, were living their lives normally when they started to hear many different voices infused with mana, warning them of the incoming danger. Most of them chose to believe on what they were hearing, because there were many known faces among the people announcing that news, that it couldn't possibly be a lie.
However, it wasn't everyone that could so easily abandon their houses, because of a vague information like that. There were those that needed to see it happen in order to believe it.
There was another problem as well... It was literally impossible to warn the entire city before something could happen, and that led to the situation they were right now.
Many elves were escaping to a safer place, together with the leaders of the Allakiir and Beihorn families, while there were many more that were watching that crazy scene from inside their houses.
