This continuation of the Arthdal Chronicles takes place 8 years after the last installment.  The King's position in Arthdal has started to weaken, throwing the kingdom into political and cultural upheaval.  And as prophecies come to fruition, the legend of the 3 coming heroes gains momentum.  While Tanya leads her followers from within the city walls, Eun Seom brings the tribes from the plains together to fight for power. And this fight will bring him face to face with his brother, Sa Ya, who is currently leading the King's army.  Now the trio will need to determine where their loyalties lie and if they can bring peace and unity to their war torn land.
