Wojira is the younger, less powerful sister of firstbourne, I think. Wojira and Firstbourne we’re both chill with Oni, but Firstbourne was more Reserved about it . Like, she didn’t enforce weird rules or anything but she also . Didn’t stop her kids from being really awful.

Wojira spent more time with Oni than other Dragons. Even her kids (wind and water Dragons) were sort of weird about it. She didn’t really like the sort of power hoarding attitude of the other Dragons and decided to teach them a lesson about it.

When the first master was born she realized that Oni blood COULD bear elemental magic, and she took in two Oni kids (Nyad and her brother who I made up and haven’t named yet lmao) and gave them wind and water (separately) magic. And the other Dragons were VERY mad about this. They thought it was disgraceful.

They tried to get Firstbourne to banish her . Firstbourne refused and so her kids just all worked together to banish her instead. And sort of gave her a fucked up cursed eternal headache (in the amulets) Whoops . Nyad and her brother followed Wojira into the realm of Ninjago and tried to ease her pain for years but eventually it just sort of broke her mind and she started laying absolute waste to everything.

The FSM goes through his whole story (still figuring out details of it in my headcanons) and comes to Ninjago, desperate for a new home. And Nyad and her brother (I really need to name them DIFNDKFM) are scared of him at first. But he shows them his elemental magic and they realize he’s like them (Oni with elemental magic). And they bond over that and tell him about Wojira. The first master decides to help Nyad convince the Merlopians and Islanders to resist Wojira and hopefully bring peace to the realm.

Over several months they become good friends, and they often calm Nyad’s brother by making beautiful little worlds out of their elemental magic for him. And the FSM promises that one day Ninjago will be safe like these worlds, and they’ll all be able to live there.

And these very very lonely people have made a little family.

Of course, the Oni hunters are sent to track down the FSM, and Mystaké is the first to find them. She announces herself and demands the first master return with her. He begs to stay just long enough to make this world safe for the people there, and she reluctantly agrees when they show her the safe world they’re planning to build. It looks beautiful.

Mystaké joins their efforts, hoping to speed along the process of the first master’s return to the first realm, but she finds herself amazed by their magic and (worse) deeply fond of the little trio. She falls in love with Nyad, and starts letting herself indulge in their hopeful fantasies of a safe world where no one will find them. In this time, Nyad gives the FSM a name of his own to use when they have their safer world. Hajime.

When the preparations are as ready as they’ll ever be, the Battle of Nine Days begins. On the eighth day, Nyad’s little brother (who wasn’t even fighting) is struck near-fatally, and Nyad launches a risky attack to try and end the battle once and for all. It’s unsuccessful, but she realizes Wojira’s weak spot. Like in canon, she merges with the sea, desperate to give the others a chance at the world they’d all hoped for, and hoping that her brother could be saved if the battle ended and he could get proper help.

She knows she should kill Wojira, but she can’t bring herself to. And instead of killing her she decides to take the amulets, and send Wojira into a deep, painless sleep, hopefully eternal.

Hajime is devastated by Nyad’s death, and though Mystaké grieves her as well, she’s a lot more accustomed to death, and watches her go, surprised by the ache in her heart.

The brother lives, but passes on his element very soon after the events of the battle, sick of it’s consequence. Hajime builds the new world and appoints new masters, though he doesn’t know where the water and wind elements went (not his domain). Mystaké never even brings up the idea of taking Hajime back to the first realm again, and protects him from other hunters when she can. Hajime lives a long long time before choosing to pass on and find peace for himself. Mystake lives another thousand years, farming strange enchanted teas, occasionally a companion to Wu and Garmadon.

In Hunted, she confides in Lloyd that if or when she dies, she would like to be sunk into the sea where the battle took place (not that she tells him the story. Just the location), and Lloyd thinks it’s just some weird senile old lady talk. But when she does die at the hands of his father and the Sons of Garmadon in Hunted, Lloyd doesn’t get a chance to row her out until after March of the Oni.
