Water is the Element of Change

Water is the element of change, it is to be replaced constantly or it becomes poisonous. Same can be said towards Avatar Korra's reign. An era needs to die in order to give birth to a new one, that includes every person whose actions shaped the era -the great and the terrible. *Sequel to "Reign of Vengeance"(AU), 2nd book of the series: When the Avatar Becomes a Tyrant*
