Entering the deep sea cavern he is greeted by the sight of the siren. It sings it' song while floating alone in the center. Her appearance familiar of a acquaintance but he knows better. At that moment his communicator buzzes.

"Doctor. I'm ready let's end this once and for all."

Caerula Arbor alternatively known as Mizuki declared.

"Understood." He replied before ending the call. As he manifests his sword entering the sight of the seaborn goddess.

Her eyes open revealing her dead irises. A smile forms on her face as her song enters a higher trill.

"I've waited for so long Doctor. Come closer please." She asks needily. "Make us whole.."

The Doctor responded by unsheathing his blade. It's steel coated in a blue ethereal glow. His expression unreadable by the hood of his cloak. Yet it knew what his intentions were.

"Of course you still resist my song." Ishar-mla muttered softly with a downcast expression. "But don't worry soon it will be only you and me now."

And with that she sings a note that releases a shockwave around her blasting whatever is in the vicinity backwards greatly. The Doctor included. Sent flying into the air he performs a aerial rave to keep himself stable before transitioning into a judgement cut. The attack was a clear hit and her blood was shed. Yet the wound healed moments later and a swarm of sea terrors immediately arrived. Her song seemingly strengthening them all.

"Come my bloodkin assist me in assimilating my dear Doctor."

Ignoring her remark he switches to his blue rapier instantly performing a helm breaker on the ground knocking away a group of runners waiting for him. Proceeding to dual wield his katana and rapier he dealt with his main goal for now. The crowd of sea terrors that Ishar-mla summoned. Avoiding the barrage of spitters he conjures a heavy rain of ethereal rapiers to rain down on them skewering them to tiny pieces. Concentrating he sees a opening after the attack and deigns it the time to perform one of his signature moves.

"Your nightmare begins here!" He declares as he performs Deep Stinger and blurs around eliminating all the sea terrors in the room. Catching Ishar-mla off guard he then strikes her. Before sheathing both his weapons to gaze at her defeated body instead only to see her smiling. Wound visible yet she still stands. She closes her eyes before letting out a sad cry as in a flash of light she transforms into a colossal seaborn. The true form of Ishar-mla.

It says no words as it charges towards him. He dodges and parries with his sword cutting it's flesh. Letting out a sharp cry it rears its tail it response as The Doctor barely dodges the counter attack sending a barrage of sharp rapiers towards it. Yet it all the blades broke into pieces before fading away the god's body being too durable. Ot floats high before sending another shrill cry as it's song resonates stronger.

Ascending to it's height the Doctor performs consecutive judgement cuts dodging it's charges before striking it's flesh with aerial raves. His attacks deal alot of damage that it falls to the ground from the sky. A shockwave is sent before the beast transforms back into Skadi's form. Damage visible on her body yet it still isn't defeated.

"Doctor just fall into my song would you?" She begs as a new song enters the air. One that mentally exhausts those those that hear it into submission. Feeling it attack his sanity the Doctor staggers before concentrating all his energy on summoning a uncountable amount of ethereal rapiers.

"Unlimited Blade Works!" The Doctor cried in pain as he launched the attack. The heavy rain of blades impaled her continuously for a good amount of time.

Hearing that the song stopped the Doctor balances himself with his katana weakly staggering watching the dust clear only to see Ishar-mla slowly walking towards him heavily injured yet healing slowly but surely. A kind smile on her face as she sings a soft yet gentle song. Staggering backwards momentarily he weakly unsheathes his blade casting aside his sheathe showing that he was on his final stand.

"Become my blood kin Doctor." She asked. "Come closer to me..."

"N-never!" The Doctor yelled in response as he charged forward and attacked only to be struck back a shockwave produced by Skadi as he is cast aside to the shallow water on the floor.

Just when it seemed as his fate was sealed as Ishar-mla approached closer to give him her 'gift'. Mizuki drops down between them as he stands defensively against Ishar-mla.

"Caerula Arbor I should have known you'd show up. I only have to deafeat you now before I can become one with my Doctor."

"The era of breeding has ended Ishar-mla. Now we will coexist with the surface. Such is the order of evolution for our kind. My predecessors and yours agreed with me now only you stand before me."

With that Ishar-mla tranforms back into her seaborn form while Mizuki fends her off with his summoned tentacles. They're battle seems to be evenly matched as Ishar-mla utilized both her forms to defeat Caerula Arbor. Only for him to slowly defeat her slowly but surely. Knowing this she shifts back to her original form and summons tentacles of her own coated with poison from the sheen on them and sends them all at him. Mizuki and Doctor have found their moment.

"Now Doctor!" Mizuki declared as the Doctor performed a judgement cut end his last move to destroy all the tentacles except one. As it struck him in the abdomen piercing him through all the way. As he lets out a cough of blood. His cloak's hood falling off due to the force.

Skadi seeing the Doctor fatally injured by Ishar-mla finally broke free and tears and guilt flood into her.

"Doktah!" She screamed only to be grasped by Mizuki as he performs the seaborn equivalent of an exorcism. She screams in pain as Ishar-mla was exorcised inside of her before she collapses unconscious yet returned to normal.

"Miz-uki. No Caerula Arbor. Finish it." The Doctor weakly asked as he sits against a corner. Attempting to stay conscious as the wound and the poison slowly kill him.

"Of course Doctor. All according to plan I must say." He praises as he releases a biological signal to all Seaborn. Pure or assimilated giving them his memories of all that is good in the world and how to coexist with all that lived within it compelling them to evolve to a point until they are able to do so.

As the signal was sent footsteps are heard as Highmore arrives with the now revived Abyssal Hunters. Who immediately go to the unconscious form of Skadi as Laurentina and Gladiia attempt to resuscitate her while Ulpian and Andreana watched with silently with concern. Highmore instead approached the Doctor. Clear concern in her eyes.

Realizing her intent his eyes widen in panic."No stay away from me. Mizuki help me ou-mmph!"

He was cut off as despite him having a literal hole through him was tackled by her. Before she forcefully kissed him. Her deep dark purple eyes stared deeply onto him. The Doctor struggled and tried to pry her off him but ultimately succumbed when her tongue met his and her saliva which contained seaborn cells entered his body. The effects of which were instant. Yet despite this she hadn't ended the session and he found himself returning the kiss much to her delight.

Mizuki sweat dropped at the sight deciding to leave them well alone. Looked towards the Abyssal Hunters as Skadi regained consciousness.

C-captain! I thought I..." She was interrupted as Specter and Gladiia gave her a hug while Ulpian looked indifferently but she knew he was relieved. It eased a bit of her guilt and she broke into tears.

Meanwhile finally Highmore ended the make out session much to the Doctor's relief and helped the Doctor up to his feet as Mizuki helped in supporting his other side. He looked towards him with a embarrassed expression. "You didn't tell me about this part you know?"

"Well it's not like you didn't like it no?" He countered with a smug smirk.

"I-I you know what let's just go back to the surface I'm sure the others are waiting." The Doctor suggested as he drooped his head. Earning a cute giggle from Highmore before she snuggled closer.

Earning a snicker from Caerula Arbor.

"Abyssal Hunters we may be interrupting a moment but would you like to join us as we go to the surface?" He asked to the group of Aegir-seaborn hunters.

As the Doctor was dragged by Mizuki and Highmore to the surface while the hunters swam from behind they arrived to be greeted by the old bishop with Thorns and Co. with Irene on the background while Carmen could be seen on the Distance talking with Lumen as Glaucus, Azurius and Aria attempted to make a fire going.

The Doctor was then pulled away by Thorns as he lead them to Elysium and Weedy. The latter of whom had managed to erect a communications station and was currently in a direct line with Rhodes Island with Doctor Kal'tsit. Explaining everything went smoothly until a gust of wind blew his cloak's hood away showing the effects of Highmore's seaborn cells. The fact that the ends of of his hair had turned into a dark shade of blue and that his irises had turned to a mix of neon blue and purple. She gave him a deadpan look before dismissing him. Thorns and co. proceeded to ask him about the details much to his chagrin.

The head bishop smiled as he listened to both his adopted children. One explaining how he shared his ideal of coexistence with the surface and the other explaining her attraction to the hooded swordsman. Giving her his blessing she's allowed to join her brother on Rhodes Island and she can even date the Doctor if said Doctor agreed. Which she took as a challenge. While her brother merely sweat dropped at her enthusiasm. Before he leads them to the three Iberians who finished starting the flame and proceeded to prepare meals for all the people involved in this event.

The Abyssal Hunters had a heartfelt reunion with the inquisitors and Lumen as they all shared with their experiences during the near second profound silence though they all agree that they're happy with this outcome and are ready for what the future had in store. Aegir was lost from what they had known. And perhaps they had to learn to live life in the surface.

As food and drinks with assuredly no Seaborn cells hidden in them was served by Mizuki and Highmore. The Doctor sat in the sand as he dissipates his sword after giving it a good cleaning. Watching the peaceful sunset and looking towards the coastal cities he knows that Iberia will have to rebuild and recover but eventually it should be the beginning of a new golden age.

Suddenly a huge splash was heard as the last knight jumped out of the ocean on his steed unto the land. Immediately suprising everyone at his intrusion.

"At last I've found you all! Don't think you can start a party here without me and my good friend Mr. Cannot now would you!" He declared as the wandering trader showed up from the depths radiating a deadpan expression despite his helmet obscuring his face.

"As as he was saying. We brought some extra food!" He explained as he unpacks a bag containing many kinds of herbs and spices and very fresh fish. Immediately catching the eyes of Specter who started going ham on the buffet. Much to Cannot's horror and the last knight's amusement.

With that the atmosphere returned to being light hearted. Until the Doctor notices Skadi sit beside him. Now dressed in the clothes she wore in sal viento. Already knowing what was on her mind he immediately addressed it.

"I don't think anyone here blames you. You know we managed to minimize the casualties so try to cheer up a little won't you?"

"I know it's just I hurt you Doctor." She explained. "I just feel very guilty."

Revealing his face he makes her look at him. Locking both their eyes together. "Look if you didn't stop then. You were truly lost so I'm glad you're back Skadi. It's time for us to move forward."

Taking his answer to heart she smiles in acceptance. "I will Doctor thank you for understanding."

A set of footsteps can be heard behind them. Turning around the Doctor sees Highmore with a rather demure expression.

"Hey Doctor that wacky salesman gave Thorns a guitar and he's been playing some music and i was wondering if you would umm..." She trailed off as her face burned brightly red. Which wasn't helped by the fact that she couldn't read his face because of his cloak.

"Dance with you? Sure I wouldn't mind." He replied understandingly as she let a out a cute eep when he took her hand and led her to the music where Thorns was playing a traditional Iberian song called el brillo solitario.

Skadi watched the entire thing unfold with a sad expression. Before steeling herself and heading to her fellow hunters. The Doctor deserved someone far better than her anyways. No matter how much her heart hurt. Indulging on that feeling was where this entire mess started anyways.

As the Doctor lead Highmore to where Thorns was playing the guitar. He could see Lumen and Irene performing a waltz while Gladiia and Specter did something probably Aegirian. Mizuki seemed to be enjoying the atmosphere while sitting next to Thorns and co.

"So any specific type of dance that you'd like?" He asked to his partner. "Im open to any that isn't very fancy."

"A waltz would do thank you." She replied as she placed her hands to the proper positions and the Doctor followed suit.

Gradually they slowly work out to a proper tempo. And they flowed with the song that was played by Thorns. Time felt slow as they danced a proper end to the entire events in Iberia. Having a sneaky idea pop into his head he takes a look at Highmore who had a satisfied expression in her face. He twirls her before catching her their faces only inches apart. Without a second thought she pulls him in. Earning a low whistle from Elysium while everybody else stared with a deadpan expression. A perfect ending to a depressing timeline.
