Six months after Itra and Danae were ejected from the Castle of Teskom, an alarming phone call sends them back and not by choice. They're not alone aided by the support of the new alliance of descendants from the bloodlines of Zeus and Mui and the Protectors of Time. They arrive just-in-time to defend the castle from Ember's scorned ex-lover Chronos. But the list of opponents evolves as they uncover an ancient prophecy of a new beginning of time between the four dimensions.
