Chapters:

Chapter One

[unknon the player’s gender, so use pron. “they”]

Player woke up in the sound of calling. They knew it was from Zoe, the researcher, yet they were unsure why she was so fretful. The noises made by various devices reminded them that they were in the laboratory, other than that, they could see nothing but plants in the lab faintly illuminating.

(restore power to continue, task by researcher)

As soon as the power was back on, they saw someone laying weltering in blood. (find clues from the body, task from Zoe) It was Nereus, the princess of Atlantis, who was the guardian of this land. Her death meant the fall of Atlantis. After scanning the body, player found out that she seemed to hobble here with all her strength [conclude from bloodstain]. It was an assassination. The wound on her waist opened up more while she was on her way to the lab, slowly taking away her life. Her scales used to be glittering with a riot of colors, but now it was shattered and lifeless. (get one shattered scale)

(discuss with researcher to continue)

Zoe calmed down immediately to analyze the situation. From the dialogue, player got to know that the scales still remained part of Nereus’ memories which would fade away in three days. Player had to collect the scales to solve the case while trying to save the sunk Atlantis (general tasks, not from npcs).

Chapter Two

In order to find the murderer, the player had to get out of the lab. (find the wetsuit to continue) As they were on their way, a woman seemed to be attracted by them. She rushed to the player, staring at the gloomy scale held by them as if she was crazy. Never had the player seen such a terrified expression on anyone’s face. It was like a mix of shock, pain and disgust. She asked the player if the princess was dead. In the gaze of startle, the woman told them that Nereus was murdered by a man who was close to her. Neither did the princess suspected him, nor saw the assassination coming. Everything went normal until the man hugged the princess. The woman seemed to have the ability to read the memories on the scales. Yet since the scale was too broken to store more information, the woman could only hear the voice and see the body shape of the murderer. Before the player left, they got to know that the woman was called Metis. (player can get clues from her after collecting the scales)

Fortunately Atlantis was quite small. The player went to the village and saw Doris was sitting in her garden, looking upset. A scale was held by her. Even if the scale’s original owner had died, it was still trying to shine in the hazy underwater sunlight. (Talk to Doris to continue)

Doris was blaming herself for not keeping the scale well enough. The scale was a gift from the princess a couple years ago. Nereus believed that her scale could protect the ones she loved even when she was not around them. Doris carefully treasured and wore that as a necklace until yesterday. When she was looking at the mirror, part of the scale was turning grey because of the death of the princess. Of course, she wasn’t aware of that. She heard some ways to brighten the jewelry so she wanted to give it a try. Please find some Fluorescent corals for Doris. (Find some Fluorescent corals and give it to Doris to continue, task by Doris)

{ps. i didnt set the amount of corals or where they were. you guys can set as you like}

The scale didn’t rejuvenate, as the player expected. Player offered that they would take the scale away to analyze the reason for turning grey and promised they would give it back. She seemed frustrated but she chose to trust them. (get one dying scale)

Chapter 3

*if the player chose to get back to Metis, she would tell the player that the scale was too damaged to be read. They should head out to restore it.

The people arguing on the street caught player’s attention. As they walked through the crowd, they saw one man screaming at another person, with eyes blazing with fury. Heph, the bad-tempered restorer, was known for his superior skills and his weird personality. A small damage of his work could trigger a fight with someone random on the street. There were rumors saying he was good at repairing only because he had to learn restoring the things he broken into pieces. (go check the situation to continue)

Maybe the Heph can help restore the scale, the player thought. They managed to stop the argument and dragged him aside. In order to persuade this stubborn man, they told him part of the story, except the death of Nereus. A lie needs more lies to cover. It was not long before Heph detected the lie. Apparently, he was furious. In spite of unknowing the whole truth, he still agreed to help them for the sake of the scale. But the prices for that were more things to collect. “It’s a fair exchange.” Heph sneered. (collect seaweed, Fluorescent corals, jellyfish, task by Heph)

*i was just randomly listing things. you can add or delete as you want.

(after giving them to Heph, player will get a normal scale)

Heph gave back the repaired scale, mumbling the people’s carelessness. Orpheus hurried to him last week, begging him to save his irises, whose pedals were like being ripped off by someone. The poor musical actor was about to give the irises to the princess but somehow the plant was dead before he sent his feelings to her. Player decided to go to the theater to meet this man.

[if it is possible, you can make player to collect stuffs and sell them to Heph for the theater ticket. otherwise just next chapter?]

Chapter 4

(After getting the thearter ticket)They successfully came to the theater,finding Orpheus crooning a sad melody.The gorgeous clothes couldn't hide the gloom in his eyes.Looing down with his eyes,a few wilted irises scattered on the ground. Players thought Orpheus knew about Nereus' death,then went up to comfort him."
