The Fifth Umbral Calamity
, also known as the Calamity of Ice
, heralded the Age of Endless Frost
. As is the case with nearly the entirety of the Fourth Astral Era
, the great calamity
which would end the period is also shrouded in mystery. Tribal legend does, however, speak of a seemingly endless winter that brought with it bitter cold, raging snowstorms, and giant rivers of ice. Without the ability to grow crops, much of the population perished, or was forced to flee to the south and its more temperate climes.
