I'd have to reread the lore but I know that either each umbral or each astral era bore a new element into the world, forget which one. That is the reason the people thought this would be the last era change because there were no new elements that could be brought into the world.

My point is the lore is setting itself up to bring a new element into existance in the coming era so it could be darkness.
