The
First Umbral Calamity, also called the
Calamity of Wind, was the cataclysmic event that began recorded history, ending the period in which the
Twelve were thought to have walked the world of
Hydaelyn.
It was not until the advent of the
Sixth Umbral Era that, by the process of elimination, scholars were able to declare with certainty that the elemental
calamity which ushered in the
First Umbral Era was indeed connected in some way with wind—possibly in the form of terrible hurricanes, tempests, or tornadoes.
Recent dealings with the moogles of
Moghome in which village elders have spoken of a wind-driven disaster previous to the first five calamities serve to further reinforce this theory.
