Reunited - A Ninjago Story

Set after Seabound(Season 14):

After Nya's sacrifice, the team fought the greatest evil ever, unlocking their new powers, and winning. Ninjago is freed from all evil.
The "four" Ninja have saved Ninjago, but moved on with their lives, away from each other, with many conditions, with the death of two teammates.
Jay - Jay is broken after not only losing Nya, yet also losing his best friend, Cole. In the final battle, Cole died in his arms, and he couldn't do anything about it. He lost Nya to the Endless Sea despite all his efforts for her to stay.
Kai - Like Jay, Kai is also sad about losing his two teammates.
Lloyd - Lloyd thinks that he has failed at leading his own team to victory.
Zane - Zane works as a master inventor for Borg Industries. He revolutionized Ninjago, expanded the City, and made many things to honor the death of both Cole and Nya.
What will happen when the four have a chance to save Nya and Cole?

Credits also go to Minecraft Story Mode. A lot of the plot is derived from their first four chapters.
