Once they've upon entering the doors, the little mermaid and her companions swam downwards through the narrow caverns. Then the waters grew ominously darker as they ventured onwards, swimming through the tight gaps one person and creature at a time. When they exited the caverns, they were all not prepared for what they've just seen. The aquatic group is at the foot of what may appear to be a triangular temple of the mythical mechanical god. The one ancient machine responsible for the Ragnarok of the Nai'Viqian race. The opposing structure of the temple immediately stroke fear upon the heroic adventurers. Not only that, Abzû notices the same triangular mines floating around the entryway. Despite of Flounder and Sebastian urging everyone to turn back, they refuse to let their fears get the best of them. After all, they've come this far just to help Abzû uncover the pieces of the mystery, there's no turning back for everyone now. They are going to see this journey through, no matter what it takes. So without a slightest bit of hesitation, the little mermaid and the adventurers proceeds to go further without clashing with the mines. With so many of the debry floating around the premises, they carefully evade the mines and successfully made it to the temple's entry. Then the doors abruptly closed behind the group. Thus they continue to swim forward inside the temple.
"What is this place?" Ariel uttered quietly.
"Oooh... I'm scared, Ariel..." cried Flounder as he swims closer to the mermaid.
"Oh mon. I don't know what 'tis is, but I don't like it." said Sebastian. "Not one bit."
"Let's stay close together." says Travannus, guarding his friends with his life. "We don't know what we're up against."
"Travannus is right." says Abzû. "This could be enemy territory. We must stick together and don't let your guard down."
"That's what I'm here for." added Travannus, flexing his muscles.
While they venture through the ruinous hallways, as well as evading the highly functional mines, they stumble upon what appears to be an laboratory. Despite of it being abandoned into ruins for thousands of years, the machines are still enacted. Horrified, Ariel quivers a little bit. But Travannus is here by her side, to ease her fears for a brief moment. Abzû lead his group of friends onward through the broken labs.
"Be careful, everyone." says Abzû as he guide his friends through the dangerous labs.
They found themselves in the center of the lab rooms. Abzû activates the panels, only to his surprise that they still work. As the gang investigates the labs, Ariel makes a shocking discovery. She views the holographic light coming from the panel in lab room number 303. It is a diagram of the marine species and the Nai'Viqian body anatomy. Then it cuts to the diagram of Duncan the great white shark. It cuts again to show the embodiment of machinery itself, the mechanical god. Then before the little mermaid knew it, the last diagram was of the same humanoid anatomy that matches Abzû's appearance. She learned that Abzû is really an instrument of Ragnorak. Created by the mechanical god and it's will. The humanoids's main purpose in life is to carry out the machine god's wishes. And that wish was to spread the roots of all evil from the oceans, to the mainlands and annihilate all traces of humanity's very existence as well as nature itself. The terrified little mermaid sunk to the floor, sobbing away in fear. After hearing her crying from next door, Abzû quickly swam into the lab. He sees Ariel burying her head into her arms in sorrow. He wonders what is wrong.
"Ariel? Are you okay?" Abzû asked in discernment. "What is wrong? Please tell me."
She can only look up at him with fear and sadness in her eyes.
"Oh Abzû... it is so terrible." cried Ariel, softly.
"What did you find?" He asked in a gentle manner.
"I think I've found the answers you were looking for." said Ariel.
This just in, Travannus, Flounder and Sebastian has entered the room, just in time to hear about the discovery as Ariel elaborates.
"When I was watching this thing-ga-bob, I've learn that these awful things were created by this weird monster." said Ariel and she went on. "And those paintings we saw along the way. They were telling us a story. A history of how they built this monster to protect their civilization. Or so they thought it was. But instead, the monster destroyed the entire race. Only a few survived but they unknowingly created another monsters after this one's image. That giant thing has been manipulating the Nai'Viqians for centuries. It wanted to destroy everything and rebuild our worlds into its own dystopian realm."
"Ok? I'm confused." said Travannus, scratching his dark hair on his head. "It does sound terrifying, but what does all this have to do with going through so much trouble for Abzû here?"
Ariel then slowly turns to Abzû, sharing the rest of the bad news.
"Abzû? As much as I don't want to believe this myself, but you're the living instrument of Ragnorak." says Ariel in a shaky voice.
Shocked by this revelation, Abzû sunk to the floor himself. Everyone is stunned by the discovery Ariel shared with them. Abzû doesn't know what to think after hearing about this shocking news. Now that he knows what he really is, Abzû stares blankly at the floor in utter heartbreak. After all this time, he was left adrift on the surface, never knowing what he was doing there in the first place. All that he discovered, all the wonderful friends he made along the way, only to find that he is one of the mechanical god's living subordinates, bound to carry out its wishes of destruction and rebuild the earth into an dystopian wasteland. The world will be filled with nothing but corruption and machinery. It is a devastated truth, even for them to hear. But before they can pause in disarray, they can hear a voice echoing out of the blue. It sounds like a male's battle cry coming from the other side of the temple. With no time to be spared, the unlikely adventurers swam swiftly out of the labs. They pass through the halls and now they have reach the chambers of endless despair. The chambers is filled with mines all over the place. The little mermaid and her companions must carefully maneuver their way through the other side without the mines harming them. This is no easy feat for the heroes. The mines hovered abruptly from one point to another. Ariel, Flounder, Sebastian, Travannus and Abzû were all hit numerous times by the mines, painfully electrocuted. Although in pain from the horrifying experience, the gang must carry themselves forward if they were to make it on the other side of the chambers. Once they've finally made it out of there alive, the group were met face to face with the one monstrosity responsible for the extinction of the Nai'Viqians and all they've created. The embodiment of machinery itself. The mechanical god. It's eye activated by itself and is now glaring upon the little mermaid and her companions. Ariel is terrified by the god's appearance and she never thought that she would come to see it up close. The same goes for Flounder and Sebastian themselves. Travannus was stunned by the sheer size of the thing. He was only frozen with fear inside his heart. As for Abzû himself, he is finally arrived to meet his maker. The mechanical god is suspended in mid water with tubes coming from each end of it. Before they all know it, the only one that took immediate action was Duncan himself, who has come to rebel against the machine god.
"YOU FREAKIN' MONSTER!" bellowed Duncan in rage. "I'M GOING TO DESTROY YOU!"
The shark thrust himself into the god's eye. Ariel and her friends were shocked to see Duncan attack the god that is twice the size of a warship. But his actions are in vain for it only cause the god to malfunction. In its wrathful power, the god charges up and unleash a massive shockwave, electrocuting not only Duncan but Ariel and her friends as well. From the excruciatingly painful attack, the heroes all have sunken into the darkest abyss below. As it may seem that all hope is lost, the mechanical god is too powerful to be stopped. And it has completely won.
