Here's the next chapter of Reunited! Enjoy!

Disclaimer: I don't own Ninjago.

The ninja and company were headed towards the Water Caves, where the legendary Trident of Water was hidden, and guarded. The ninja were out on the deck training. The girls were on the training course trying to learn Spinjitzu, while the boys were sparring of giving them pointers, such as to flip, dodge, bend knees, or roll. So far, Karen was the only one of the girls who could do Spinjitzu, but Clare wasn't far from it. She could clear most of the training course, but she kept falling off balance as she was trying to pass the dummy. Serena kept falling off the planks, as did Crystal, and Sarah couldn't quite yet dodge the swords. But then again, she's only been here for a couple days. After a few minutes, Nya's voice could be heard over the loudspeaker.

"We're about to arrive at the Water Caves. Time to get out the diving gear!" She informed.

"Diving gear?" Cole wondered.

"Dude, we're in the middle of the ocean, and it's the Water Caves! Which means it's underwater." Kai stated. (A/N: Kai is not afraid of water in this story.)

"True, but water caves don't nesscessarily have to be underwater. They can be behind waterfalls as well." Cole argued.

"Yeah, but the one we are going to is underwater." Kai pointed out.

"Guys, please stop arguing with each other, and come on up to the bridge!" Lloyd called out. The two ninja made their way up to the bridge, where everyone else was waiting. As soon as they were all in the room, Sensei Wu cleared his throat.

"As you already know, we have arrived at the Water Caves, where the silver Trident Of Water is located. You will need to put on these wet suits, these oxygen tanks, and other scuba diving gear to get down there, as the caves are way down at the bottom at the ocean." He informed. The ninja nodded their heads.

"Now, let me tell you a little bit about the silver Trident of Water. As you know, it was created by my mother, along with the other Silver Weapons, just like my father created the Golden Weapons. The trident can shoot water out of the tines and the handle. It is in the middle of an underwater cave pond. You will have to swim to the small island in the middle, to get to the trident, Karen. However, it won't be that easy. Just like with the Golden Weapons, there will be a guardian protecting the weapon, same with the other Silver Weapons. All you have to do, is make friends with the guardian, convince it that you are taking the weapon to help protect it, just like the guardian is doing. Then the weapon will be all yours, Karen." Sensei Wu explained.

"Okay," Karen replied nervously. She wasn't sure about the guardian. She knew it was a dragon, because she watched her brother's adventures with Jay, Zane, and Cole, including when they gathered the Golden Weapons. She knew it wasn't might not be too easy, but she had to get the weapon, so she needed to take this challenge. They all exited the room to go slip into their diving gear, and soon they were all in the water ready to go down to the Water Caves. Garmadon, Misako, Richard, Mary, and Dr. Julien wished them luck.

"Good luck and be safe, ninja." Sensei Wu added. They bowed the best they could in the water and the scuba diving gear, then they dived down into the deep, dark sea with their oxygen tanks activated.

"Guys, I think I see the cave!" Jay exclaimed through his helmet. The others looked, and sure enough, the entrance to a cave was there. The ninja swam down and entered the cave, and looked around. Karen looked up, and there she could see the surface of the water inside the underwater cave.

"There!" She pointed up, and started swimming up, as the others followed her. When they reached the surface, they noticed a dry ledge to stand on, a small island in the middle, and most importantly, the Trident of Water shining on a pedestal in the middle of the island. Karen started swimming towards it.

"Remember there's a guardian! You have to make friends with it!" Kai warned.

"Yes, I know." Karen assured. She continued to swim towards the small island. Once she got there, she stopped and stared at the awesome sight in front of her. The silver Trident Of Water was sitting right before her, on a silver pedestal with a silver dragon it.

"Wow," She said in awe. The other ninja watched as she slowly walked toward the pedestal, then she slowly reached out to touch the Trident, which instantly soaked her. Not that it made much of a difference though, as she was just swimming in scuba diving gear. After that show, she grabbed the Trident and pulled it off the pedestal. The others cheered, but quickly stopped, as there was a bright flash of light behind Karen who slowly turned around. Behind her was a menacing, growling, but magnificent and beautiful dragon. The dragon was female with dark purple and silver scales. She had silver spikes running along her back and tail, which had a silver dagger-like tip on it, silver outlining her wings, a silver underbelly, and silver claws, with gills and lungs, light purple eyes and pearly white teeth. Karen knew that this was the guardian.

"Okay, make friends with the dragon guardian." Karen said to herself as she faced the dragon, who growled in response.

"I assure you, I am just here to protect the Trident, just like you are." Karen assured the dragon, who stopped growling and stared at her for a moment, before turning around and looking back at Karen, smiling the best a dragon could, indicating for Karen to climb onto her back. As she carefully did this, her teammates watched her. Once she was on, her teammates cheered for her, as she had befriended the dragon.

"I think I'll call you…Aqua?" Karen suggested. The dragon nodded and smiled her dragon smile, seeming to like the name.

"Aqua it is then. Come on guys!" Karen put the Trident in a protective case, and strapped it to her back, as Aqua dived into the water with Karen on her back, and the other ninja followed suit. They swam back down to the cave entrance, where Karen let her teammates swim past, and she made Aqua wait a minute before continuing to swim towards the surface.

On the Bounty, the adults were waiting for the teenage ninja to return from the Water Caves. Soon nine ninja surfaced, and climbed aboard the ship. Only Karen was missing.

"Where's Karen?" Mary and Richard asked. Kai opened his mouth to answer, but before he got the chance, the Bounty started to shake. Then there was a huge water explosion, and Aqua the dragon emerged from the surface of the water, with Karen on her back.

"There she is," Kai pointed out, as if the explosion of water wasn't enough to alert them that Karen was here. As she landed on the deck, they noticed that she had the Trident Of Water on her back, and cheered. Karen took it off her back and out of its case, to let everyone else admire it along with Aqua.

"I can't believe it got the Trident Of Water, and a dragon!" Karen exclaimed.

"I can't believe it either honey!" Her mother and father cheered, along with Kai, Nya, and the others.

"Btw, I've decided to name the dragon, who I think is a female, Aqua, which I know is spanish for water." Karen informed, which everyone agreed that Aqua was an awesome name for a female water dragon. Then Sensei Wu spoke up.

"Now that we have the Trident Of Water, it's time to search for the next silver weapon, the Double-Sided Scythe Of Metal." He informed.

"Awesome! That's my weapon!" Clare exclaimed, excited.

They have the first weapon! Now onto the next! Idk when the next update will be, because I have so much other stuff, and other stories, but there will be another update, they will find the next silver weapon eventually! Please leave a nice review! Thanks!
