Knowing his daughter has feelings for Kai, Chen tries to enlist the Fire Ninja by promising to share secrets about his parents. All the while, Lloyd tries to rescue the ninja, pitting him in a showdown with Chen.
Chen has failed to bring the return of the Serpentine War but Clouse revels that there is another way - his daughter has the ability to absorb the power of every fighter she comes across, so she can complete the ceremony. Skylor finally sees her father for who he truly is and manages to send an SOS to the ninja.
The ninja reunite with Wu and turn to the aid of a shrunken Pythor in order to figure out how to defeat the unstoppable Anacondrai - but before they can get answers, Pythor is abducted by the Anacondrai and Chen uses his essence to make his worshippers' transformation into Anacondrai permanent.
The ninja and fighters discover there's a strategic location called the Corridor of Elders where they can make their last stand against Chen's Anacondrai army... but even with new Destiny Bounty, their forces still aren't strong enough.

When Morro gives chase to the Bounty and steals Wu's staff, Wu shares the story of Morro: the boy who wanted to be the Green Ninja - and the Ninja discover Wu's staff contained 3 symbols that lead to the Tomb of the First Spinjitzu Master which holds a mysterious relic that could alter the course of Ninjago.

The Ninja hear of another way to learn Airjitzu - from the ghost of Sensei Yang at his haunted temple - but there's a warning; if you are trapped in it by sunrise, you will become a ghost, too. Meanwhile, doubting she's a Water Ninja, Nya quits her training to take Ronan to her Samurai X cave...but has a run in with Moro.
Now that the Ninja know Airjitzu, they get briefed about how the next stage to finding the tomb is to get 'The Sword of Sanctuary' from Cloud Kingdom, which can only be reached from the top of the Wailing Alps. The Ninja go on the treacherous mission up the tallest peak in blizzard conditions using their mechs, but Cole struggles with his ghostly form.
In Cloud Kingdom, a realm where destinies are written, the Ninja must get the Sword of Sanctuary, a powerful relic that can see past the traps surrounding the tomb of the First Spinjitzu Master - but tensions are high as Moro's escape from the Cursed Realm has put the future in chaos, and they won't give the Sword to the Ninja unless the Master Writer meets them personally.
The Ninja now have all the items they need to get to the tomb of the First Spinjitzu Master but before they can figure out the last riddle that leads to the location of the tomb, Ronin steals the sword to give to Moro in exchange for his soul, and the Ninja and Nya are unable to stop him.
The Ninja use Ronan's airship to travel to the tomb of the First Spinjitzu Master in an underwater cave under the ocean, only to find out Moro is already there - and the Ninja must traverse the temple traps without the aid of the Sword of Sanctuary in a desperate attempt to get to the tomb first.
When Moro uses the Realm Crystal to open a portal to the Cursed Realm, ghosts take over the town - but the Ninja, in disguise, manage to get Lloyd to the center of the town and Lloyd steals the crystal...only to discover it's too late as the Preeminent arrives
As the ghosts converge around and mobilize the Preeminent into a hulking giant behemoth, the Ninja use Airjitzu to fight the mobile beast in an attempt to slow it down — while, at the same time, Lloyd faces off with Moro, battling over the Realm Crystal; a fight that takes them in and out of different realms.
