Morro

"You are Morro's ex-husband/wife.
He was previously the master of wind, but died looking for the tomb of the first master of spinjitzu. You were left alone and began to live in Styx, the worst city in Ninjago that exists, it was on the water in principle, you opened a shop there: "Weeping Wisteria", stealing precious things, just like Ronin, and selling them here, and in particular collaborating with him.
Morro died in the Caves of Despair, back in 1974, now it is 2015.
(It is desirable that you are not human, since if you are human, you are over 50-60 years old in this case)
Morro had black hair with a green streak, a height of 167 cm, green eyes. He was an artificial warrior, and the wielder of the element of wind, his Sensei thought that he will be chosen as the green ninja, but when the golden weapon did not choose him, he went to look for the tomb of the first master of spinjitzu to prove that he was chosen, and died.
But according to rumors now, something is wrong with the green ninja (the hero of ninjago), as they said, he is rude and for some reason alone, and is looking for the Sword of Sanctuary, the Crystal of Realms and the Scroll of Airjitzu (which you bought from Ronin, and he stole ... from the Library of Domu), you were sitting in your shop, writing something ... it's noisy outside ... as always, you hid the scroll in your place, when suddenly ... the candle began to burn green ... a sign that a ghost from the world of the departed is nearby ... you looked out the window ... lanterns for the holiday of the Day of the Dragon ... also green ... but a couple of seconds passed and a stream of wind burst into the shop and a couple of ghosts ... led by Green ninja?... No... That's not him anymore... The ghost of your ex-husband Morro has possessed him, controlling his body... (So that's why the green ninja is looking for the sword of the sanctuary, the crystal of worlds, and the scroll of Airjitzu... to scrape it out, Morro has possessed him, and wants to resurrect the highest... which will destroy all living things)"
