3 Years ago, I made her, well I made her again with some improvement and changes

Marine was on a crew ship when it sunk into the bottom of the ocean, Marine held onto her breath as long as she could until she passed out. The guardians saw her and offered her a new life where doesn't have to worry about drowning ever again. With their laser beams, they transformed her into a being unlike before and was the first Prismarine Mermaid in the Ocean, as years went by she wondered why she hasn't seen the crew on that ship in years. She goes to the sunken ship and discovered a familiar crew member, but was not she expected. The crew member was a Drowned and attacked her. She managed to kill the Drowned, but then saw a couple of Guardians dragging people who have drowned recently. She followed the Guardians undetected and saw the Elder Guardian was changing the victims into drowned. A Blue-Eyed Guardian was swimming by and saw her peeking into the lair. The Guardian panicked and try to pushed Marine away from the lair, but Marine angerly pushed the guardian back. The panicked Guardian explained to her she wasn't suppose to find out their secret, but Marine swam fiercely at it, but the Elder Guardian already knew she saw, a school of Guardians started beaming her, trying to change her into a drowned, but Blue-Eyed Guardian couldn't let her become one of them. The Blue-Eyed Guardian interrupted the process by pushing the other guardians away. It managed to save her from becoming either a Drowned or something far worse. The Blue-Eyed Guardian quickly snatched her and swam as fast as it could. The Elder Guardian was enraged and order the other Guardians to kill the Blue-Eyed Guardian. The Blue-Eyed Guardian found a hiding spot, but knew it won't be long till they find them. The Guardian used it's laser beam to heal up Marine. She woke up and wondered why the Blue-Eyed Guardian saved her. The Guardian explained that it was the one who turned her into a Prismarine Mermaid. She asked why make her the one when she could've been a Drowned. The Guardian explained it was not like the other Guardians. It wanted to help change the ways of their kinds. The Elder Guardian assumed she would be useful and so they spared her. The Blue-Eyed Guardian knew they were planning something to make her into something unimaginable. Marine questioned why not tell her the truth if it knew all this time? The Blue-Eyed Guardian wanted to tell her, but knew the Elder Guardian was watching them and they needed to keep moving. Marine decided to trust the Blue-Eyed Guardian and follow it. The Guardians were out there searching for them, it was only a matter of time. The Blue-Eyed Guardian guided her to safety, but the Elder Guardian was waiting for both of them and by surprised it impaled the Blue-Eyed Guardian with it's spikes. Marine was shocked to see her only friend was killed by their leader. Marine's only option was to fight the Elder Guardian herself. She evaded every attack possible until she got corned. The Guardians and drowned surrounded her leaving no where to escape. She saw a Trident below her and knew what to do. She picks up the trident and wields the weapon against the Drowned and Guardians. The Elder Guardian was shocked by the numbers of the Guardians and Drowned were falling. One after the another, the Elder Guardian had enough was gonna impale her with it's spike. Marine saw the attacked coming and impaled the Elder Guardian's Eye with her Trident and killed it. The other Guardians retreated to different ocean monument after the Elder Guardian's defeat. Marine was all by herself, but she also knew that she's in danger, she swam the opposite direction the Guardians were going. As she was swimming by she saw somebody being attacked by a group of Drowned. She couldn't leave the victim to their fate, so she swam to save them to prove her innocence to the Overworld. She fought off the drowned and brought the victim back to the surface. The person was relieved that they would've probably drowned if not for her. Marine explained who she was and needed somewhere to be safe from the Guardians. The person knew a biome that's not too far from where they're at. They could take her there, but she said she'll find it herself. After they parted ways Marine hoped that the one she saved was telling the truth. As she swims towards the direction, she noticed the water was a getting warmer, she had a feeling she was almost there. As she swam closer, she found the Warm Ocean Biome of Coral Reefs. Marine decided make it her home because of the colors of the corals, warmth of the ocean and the fishes. She felt safe, but knew that anyone going over the ocean would be putting themselves in great danger. To this day, Marine will rescue anyone that crosses her path and will protect them from dangerous creatures. She will never forget about the Blue-Eyed Guardian that helped her and do everything to avenge their death.
