>Phrolova saved the last fragment of Leviathan in Mya's gem
>The Fractsidus runs experiments on it
>Turned out the Fractsidus were created by past Rover
>Everything, even the Imperator and Leviathan was manipulated by past Rover, Crow Loli (Red Shokie) and the Fractsidus to obtain a small, extremely weakened fragment of a Threnodian to mold it
>After a bunch of experiments and help of current Rover after he goes to the Fractsidus, by filling Leviathan with lov, the new Leviathan is reborn, with human and mermaid forms that she can switch at will, using a trident that can turn into double blades to dual wield
>She now loves Rover, and loves human as much as Nanami and want to protect humans
>Leviathan becomes the new protector of Rinascita and Solaris-3, as both the new Sentinel and the Threnodian controlling the Discord in Rinascita. No longer harvesting civilization information for the Agent Zero
>Levi even reform the Order to actually be good, making Phoebe the new Primus
>Cartethyia is surprised and even get angry at Rover, but stop after she saw Leviathan kneeling at Mya's grave and sincerely apologize to her
>Agent Zero is VERY angry, branding Leviathan a traitor for betraying her purpose to harvest the information of the targeted civilization, and sent the other Threnodians to eliminate Levi, they also got angry at the traitorous Threnodian
>Leviathan stops the other Threnodians with her Threnodian authority and powers, controlling Dark Tide, Tacet Discords to protect Rinascita
>In an ironic twist, Leviathan became a rebel against her creator to protect humanity, no longer a tool, just like her creations Cartethyia and Mya
>Agent Zero still has her task to harvest this targeted civilization to finish, and bring the information to the Gate for "Them", the higher beings. And she has plans to deal with Levi and Rover, the anomaly.
