The aquatic gang venture onward through the pathway, leading them into the halls of another ancient paintings on the walls. Whilst swimming by them, it appears to tell them another story. During their time, the Nai'Viqians has also worship another god. It was a great white shark that might have resembled Duncan. The one shark whom Ariel and the gang encountered on their journey. As the story unfolds, it seems that most of the Nai'Viqians have had enough of their mechanical god and the traditions the alpha rulers built within their civilization. So they turn to worship a majestic shark instead. The shark embodies the strong power and wonders of the seas itself. The little mermaid and the gang read the ancient paintings of the historical accuracy while swimming through the exit of the hall. They've had entered the abyss, where there's no floor beneath them or anything else. Just a big school of fishes swarming around the place. A wondrous sight to behold. With Abzû leading the way, they all have swam through the funnel of swarming school of fishes. At the end of the path, the sound of the whales' songs can be heard. The gang stops by a lone shark statue for a slight moment.
"I wonder where's the sound coming from?" wondered Ariel.
"Beats me, Ariel." added Flounder, shrugging his flippers.
"Let's just hope it's not the sound of us becoming someone's lunch." said Sebastian in a concerning tone of voice.
"Oh Sebastian. You worry too much." teased Travannus, folding his muscled arms. "It's just the sound of whales singing a tune. No harm to that."
Abzû sat on top of the sculpture and he went into his deep meditation. His sonic telepathy envisions the whales passing by the ravine. Then a tiny tropical fish swimming along and multiple grey sharks passing by the triangular door at the edge of the cliff. Now he knows where to go.
"Everyone, follow me!" Abzû called out to them. "I know where we can go!"
They follow Abzû upward to the cliff. There they have found the triangular door on the rocks. The door has open by activation once approached. Then they enter the doorway. Once they've swam to the other side, the sea change colors again. And this time, it is as orange as the sunset. The door shuts behind the group. Now they must swim forward down the path of the kelp forest, ultimately leading them to the giant iron chains laying around the ruins. They followed the chain wherever it might take them to. It lead them to the ancient ruins covered in fall-like kelp. As the gang explore the place, they were greeted by the sunfish who acts as their guide. With it's help, they have found the turning anchor line. It must be tied to the giant chains. Out of the slightest of curiosity, both Ariel and Abzû each took a side and the they turn the wheel around. Thus loosening the chains in motion. It looks like as if it is the key to unlocking the ruins' doors. All they have to do is find the other anchor line. Whilst venturing through the red kelp, Abzû found another small robot that he can fix. All good as new. Now he just have to free the stingrays from their prison. Then they all continue to follow the path. The aquatic group found the second giant chains but it was blocked by the coral. So the small robot cleared the coral away for the gang to swim through. Once inside the cave, they have found the other chain anchor. Ariel and Abzû tries to turn the wheel but it was too stiff due to the rusty gear for thousands of years. Since he is the only muscle of the group, Travannus helps them turn the wheel. And it's finally turning. The chains has loosened and the doors has slowly opened. The little mermaid and her companions swam towards the doors. But first, Abzû has to free the Zebra Sharks from the platforms. Along the way, they've encountered a pod of manatees who wave at them as they were passing by. As they've entered the doorway, Abzû freed the lion fishes during their journey. Then the waters turns into a deep shade of blue green. All the while as they passed by the glittering caverns. It so happens when Ariel saw Duncan the shark swimming by the reefs beforehand disappearing again. The gang navigates through the caves, until they found their exit. Now the ocean floor has darken. But luckily for them, a blue light appears from the abyss below them. It was another pillar with the portal on top. The aquatic group knows they must enter the portal to another twilight realm of the gods. This time, it is Abzû's turn to touch the ethereal waters. The luminous blue light led them to the shrine of the ruins. And they indeed have followed it there. The little mermaid's group has made it to the shrine. There they stood before the lone bubble.
"Ok! This is it." says Ariel as she turns to the others. "Are you guys ready?"
"You bet I am." said Travannus with strength.
"I'm ready when you all are." said Abzû as he puts on a brave face.
"Then there is no backing out now." Ariel said with a princess's pride. "Let's do this together."
"Yeah, about that. We'll be right behind you guys." said Flounder as he hid himself into Ariel's hair.
"I'm with Flounder on 'tis one." says Sebastian as he too hid behind Travannus's dorsal fin. "Just let us know when its over."
The mutant merman rolled his eyes in a slight annoyance. As the three figures came to an agreement, they placed their hands onto the bubble. Thus it fused with Abzû's essence in an instant. What followed after the rumbling sensation, out came the trio of whale sharks ascending towards the ocean world. And their natural habitat has been restored. The little mermaid's heart has melted, knowing that the more they help the other marine life, the more of the ocean habitats are restoring back to the way they were before. The whale sharks, being the kind and gentle giants that they are, thanked the little mermaid and her companions for bringing restoration back to their waters. As for their appreciation, the whale sharks offered the gang a ride to the far off open doors. Miles away from there. After a long minute ride, they arrived at the foot of the doors. They all have said their goodbyes to the whale sharks and the gentle giants swam off, biding the adventurous heroes farewell. Now the group must hence forth through the doorway and continue their journey for there's still much to be done. Freeing the aquatic creatures, restoring the rest of the oceanic habitats and finding the answers to the truth of Abzû's past.
