But Arden and the Imperium Cadre will find the road to the past riddled with battle, betrayal and millennium old secrets. To uncover the answers they seek, they must trust in the strength they find together, or all will be lost.
For when the fierce winds of change blow, hidden agendas and powerful enemies are unveiled.
