The Seventh Umbral Era began when the Sixth Astral Era collapsed in its 1,572nd year, heralded in by the events of the Calamity. The Divine Chronicles of Mezaya Thousand Eyes, an ancient prophecy, predicted six cycles of astral and umbral eras, one for each element. The authenticity of the more recently found seventh verse was considered debatable until the Sixth Astral Era collapsed, leading many to fear that this final umbral era would represent pure oblivion and herald in the end of the world.
