It is shortly after the Day of the Departed and all has returned to normal in Ninjago. While the Ninja are back at the museum cleaning up the mess they made, Master Wu waits alone at his old Monastery. Soon, there is a flash of LIGHT and an old enemy mysteriously appears. Wu and the stranger engage in an epic battle which we soon learn is actually the finale of a fight that began forty years ago between the Elemental Masters and the Hands of Time. Who are the Hands of Time? KRUX and ACRONIX, two fallen Elemental Masters who could once control time itself before Wu and Garmadon barely managed to strip them of their time-shifting powers and transfer them into four TIME BLADES! Wu and Garmadon sent the Blades into a temporal vortex and Krux and Acronix followed, leading our heroes to think the threat was over.
They were wrong.
Now Krux and Acronix have returned and each moment a Time Blade appears in Ninjago, it wreaks havoc. Even worse, Wu made a mistake going to the Monastery alone and is been hit with a punch that causes him to rapidly age. Now the Ninja are without the day-to-day services of their master as they try to retrieve the Time Blades before they fall into the hands of their new enemies. Even worse, Krux and Acronix have at their disposal the VERMILLION ARMY – a force of armored snakes descended directly from the Great Devourer himself – and they’re using them to steal people, materials and even Cyrus Borg for a mysterious project…
It’s against this backdrop that Kai and Nya finally learn the truth about their long lost parents, Master-in-Training Lloyd tries to fill in for a weakened Wu and an all-new Samurai X returns. And not a moment too soon! The Ninja are going to need all the help they can get before the Hands of Time use the Time Blades to return to the past and undo Ninjago history. Because as Krux and Acronix say:
Control time, control everything!
