Age of Ruin — Trench Observatory
The Trench
At the bottom of Seabase Undine, Song divides the work into two desperate tasks. She must find Noelle and wrest away control of the base and Sparagmos’ data; the Hero must negotiate with Kathool. If that fails, Song tells the Hero to take Fa and run. The Trench Observation Deck once developed Swordhaven’s arsenal, but Noelle remained there after the Temple’s embedded Elf songs lured Kathool into the nearby trench. Song now wonders whether observing its slow death was preparation for killing others like it.
The leyline below the base complicates Noelle’s account. She had told Song it ran dry long ago. With the Ashray massacre exposed, Song suspects the loss of those who maintained the Temple’s concealment mattered to what happened here. Chrysoar opens a video feed to Tara, who recognizes mana from the Core and associates its surge with the Mana Crisis. Little remains: something has taken it.
Fa bets on Neso because her Titan retained blue scars that should have vanished after the Mana Crisis. The Hero considers whether that stolen mana could explain her ability to dissolve Kathool. Tara has another idea linking the leyline to the masks’ apparent foresight of three threats, but considers it unsafe to explain now. Mi asks to speak with Song; Song refuses while Noelle and Kathool remain urgent. These are leads and suspicions, not a settled account of the mana’s theft.
Circe warns that water pressure has crushed half the deck and that even arcane protection cannot make the descent safe. Her invitation to settle regrets meets Song’s insistence that she alone should carry hers. Dage’s other artificial voices turn to their maker: Lycegenes asks whether the real Laken betrayed him, and the Hero answers that Dage first betrayed Laken’s expectations. They see his continuing hurt as a capacity for growth rather than indifference. Song envies even this Evil being’s human origins.
The Hero’s negotiated strategy reminds Lycegenes of Nation contracts. Dage has already left after working out its details. Meanwhile, the artificial intelligences hold Kathool’s influence at bay, though Song cautions that it may simply be toying with them. Lycegenes lays out the route through turrets to Ganx on the first landing, then through the exposed deck to Noelle and Kathool. He cannot yet distinguish hallucination from a seafloor becoming an extension of Kathool’s body; unchecked, he warns, that change could spread everywhere.
Ghosts of the Greater Good
Song’s ten main tasks begin after Together as One and are recorded as once-only progression. Unsung Heroes sends the Hero to speak with Fa and recover eight wraith identity cards. The ghosts still believe Noelle’s promises. Their names recall researchers screened by Noelle and the Queen, who accepted danger in the hope of giving their loved ones a peaceful future. Song sees instead another peace built upon innocent graves.
Fa is preparing a real bodily transformation, with snapping bones and gurgles, to prevent Song from throwing herself away. Astravia and the Mana Crisis have made Kathool’s nightmares less frightening than reality. Fa’s growing horns must be peeled away, and the stronger form comes with fear of returning to an earlier self. Asking the Hero to keep that from happening is both a warning and an act of trust.
Watertight Guarantee requires eight turret screws and an examination of the deck. Song recognizes the guns she brought from Astravia for the base’s outer walls; someone moved them here without her knowledge. The tightly sealed door is not protecting the next landing from the ocean. That section is already exposed. It is keeping Noelle’s followers away while she remains outside with Kathool.
Core Electrolytes has the Hero inspect four leyline nodes. Song considers whether more lie outside and whether Neso drained them remotely through Water Elementals. Core Mana might let her survive consuming Kathool. The Hero’s recollection of Darkness Elementals in the Mana Core offers another possible connection to the colossal body outside. Song explicitly regards the evidence as too early for conclusions.
Guardian Spirits requires ten exorcisms because the wraiths keep returning. Song believes Noelle is turning their devotion into a weapon. The work brings back Song’s own history: Drago killed her mother through a coup supported by Astravians hostile to Outsiders; before finding acceptance at Undine, she had drifted through life as a monster or circus curiosity. Now the place that loved her has made her one of the reasons its dead cannot rest.
A Lost Signal
A separate encounter opens after Guardian Spirits. Managarmr, previously a lost figure amid the hallucinations, identifies as a member of the Ars Panopticon, S., with UID 1.1039-9. An introduction begins with “Joru” before a hurried correction to Managarmr. Having spoken with little but rocks for some time, the traveler mistakes the Hero for a rescue or a new model and demands a UID, assigned sector, companion and mission report. The Hero’s ignorance becomes, in Managarmr’s explanation, a damaged core and lost memories. That explanation establishes the traveler’s assumption, not the Hero’s nature.
Managarmr offers to strike the Hero to restore those supposed memories, then invents a mission instead. Returning with organic samples might lessen the punishment for getting lost and provide a reason to return to the Panopticon. The optional C:\\The Depths are a Harsh Mistress asks for five Squishy Organic Thingies from Sea Spirits: unfamiliar jellyfish seem oddly adorable to the traveler. The captured quest is repeatable, separate from Song’s main route.
The samples initially keep moving, then sink to the bottom of the container, prompting confusion about organic life. Managarmr offers old equipment and proposes building something the Hero can wear; gear wreckage and a possible linker give that proposal its practical reward. Neither the exchange nor the interrupted name explains where the Panopticon is, why its member is stranded here, or whether the Hero fits any of its categories.
Chaotic Rescue
Enemy in Need reveals the door’s power source: Xang, held on another draining pedestal. Six turrets must be disarmed and four wires removed. Song recognized Ganx’s identity at once, but Noelle’s assurance of plans had not told her those plans meant using Xang as a battery. The information leaks were bait. Xang confirms that Noelle drew her in with a hint about Drakath’s burns, then thanks the Hero for a rescue she says is three weeks late.
Xang wants to take the Champions’ medicine and leave. Song judges her too badly wounded to make the exit and upholds her oath to do no harm. Treating an enemy immediately draws Noelle’s objection over the broadcast: mercy to wolves, a benefactor told her, is cruelty to lambs. Medicine for Xang might enable further harm, while Drakath’s death would, Noelle insists, let Lore and the researchers flourish.
Xang counters that Noelle helped bring Drakath into the world. Noelle admits being among the Court Magi forced by his father to research the forbidden magic that enabled his birth. She treats giving Swordhaven the power to defeat all future Evils as the price of atonement. Xang’s later account adds that the Queen of Monsters was sealed away and that the magi’s work left them mutated and cursed to long suffering lives.
The alliance is temporary and openly vindictive. Xang wants to reach Noelle, and warns that the prospective enemies are not limited to Chaos or the Empire: anyone outside Swordhaven’s flag could be a threat. Fa hears a plan for war. Song denies that Victoria wants it and suggests the Jus Divinum instead. Xang attributes her information to what she heard while captive; the exchange leaves the Queen’s knowledge unsettled.
Noelle’s appeal to home, family and a better world drives Song into panic. The Hero orders the audio cut. Circe detects a frequency resembling Kathool’s psychic attacks, while Song suspects that Noelle has begun consuming its flesh after failing to eliminate Dage. Song refuses to excuse her as insane and turns that same accusation on herself. The Hero stops the spiral with Fa standing nearby. The immediate rescue has exposed how thoroughly Noelle can use Song’s longing for a home against her.
Where the Seafloor Changes
With Xang freed, the door no longer has power to keep it shut. Here Lies Shadow requires a conversation with her, two inspections of the colossus and one of the beckoning tentacle. The Water Elves’ account called the body a colossal Darkness Elemental; the Sparagmos scans disagree, identifying something other than Darkness. The Hero compares it to creatures from the New Temple of Light. The inert body is not the immediate threat, but its identity remains disputed.
Nature’s White Noise turns the party against older, angrier Sea Spirits trying to drag them down. Ten Spirit Bells clear a way to proceed or retreat. Song says these jellyfish preserve the souls of mortals Neso favored, keeping them from the afterlife to extend her influence. She recognizes affection on both sides but condemns the Avatar’s treatment of people as possessions. This is Song’s account of Neso’s favored dead, distinct from Undine’s researcher wraiths.
The spirits become too numerous to fight without risking the base, forcing a descent along Kathool’s tentacle. Dreams Seep into Reality requires three Coral Horns from the waxy Adipocere, while Song asks the party to keep Xang from taking them as accessories. The trench walls themselves resemble those creatures and sprout coral horns. Song now fears physical terraforming driven by Kathool’s influence, spreading toward the surface or becoming another power Neso can steal.
Hadal Havoc is the final approach: three Waxen Limbs, seven Spirit Stingers and the search for Noelle. Song remembers mutations that had confined Noelle first to a wheelchair and then to complete immobility while they pursued treatment and the Queen’s forgiveness. Consuming Kathool has aggravated them. Song doubts that persuasion remains possible, but the failure of that hope is personal as well as strategic.
See You on the Other Side requires defeating Lady Noelle. The Hero, Fa and Xang are to fight and remove her from the wall while Song climbs toward Kathool, keeping its attention on the battle. Song has no expectation of defeating it alone. Her final solution is already framed by the conviction that, since she cannot earn forgiveness, her death must mean something.
Our Swan Song
Kathool watches mortals feast on what once made them afraid. Noelle, fused into a monstrous form at its side, repeats the bargain imposed by the Hands behind the Queen: destroy Evil or never have a home. She invokes Song’s royal birth and claims that the other researchers and those seeking redemption are servants of the nobility. Song rejects the dream precisely because it has no place for Fa or Mi.
Song begins their Swan Song, perfected with Water Temple music and requiring no seeds. She intends to burn their life force, taking Noelle and Kathool with her or at least slowing Kathool and Neso. Noelle protests that it may not work. Fa refuses to let Song make that sacrifice, but Kathool blocks the rescuers, fascinated by the duet and ready to cast them back into nightmares.
Fa changes into a red and black, long-eared form and reaches Song, holding her while she insists that the song cannot stop once begun. Kathool calls Fa a child abandoned by the stars. Fa’s reply rejects Song’s moral arithmetic: this will not erase Evil; it will ruin Fa’s life and Mi’s. The rescue gives bodily force to the promise made before the descent.
Xang still hates Noelle, but acknowledges the debt of Drakath’s birth. With her remaining Chaos magic she offers another cruel choice and asks how much of Noelle’s professed love was true. Noelle’s last words to Song abandon earned forgiveness as the condition of living: make others happy, and perhaps find joy in doing so. Noelle sacrifices herself; Song survives. The result does not erase Noelle’s earlier choices, but it breaks the expectation that Song must die with her.
Orpheus overrides the mute command and resonates the Temple’s music with the Chaotic Swan Song. Kathool’s influence falls to almost nothing, but the system cannot undo what Neso has already taken. Song asks whether she is hearing her father. Dage explains that their nervous-system connection through Sparagmos had given him enough time to create Orpheus and see her self-destructive plans. The Hero had counted on Fa to rescue Song; Xang’s assistance was an unforeseen addition.
My God of the Depths
Dage admits that no one is invincible: not Kathool, not himself, not even the Eternal Dragon. He thanks Kathool for the clarity that has stripped away his facades. The Hero presses the creature on its suspicious willingness to be dissolved. Kathool concedes that absorption might only give it another form, corrode Neso’s mind and end in boredom, though this exact event has never happened in any universe it knows. The danger to Lore is greater than the apparent danger to Kathool.
The Hero offers something more durable than novelty: eternal entertainment as an appointed Adversary, a counter to the Creator. Kathool understands the proposal as godhood, its loose roots planted within this universe. The Hero can claim the Creator’s authority but does not know the ceremony. Kathool has watched past Creators crown new gods as old ones decay, and agrees to teach it.
Kathool instructs the Hero to recognize it as “The God of the Depths.” The Hero instead says “My God of the Depths.” Kathool accepts before realizing that the altered wording has bound it to the Hero’s powers and existence. If the Hero goes silent, it loses everything, without another reset: only a void remains. The contract gives Kathool a stake in the Hero’s continued existence.
The price is neither peace nor obedience. Kathool promises endless nightmares as the Hero’s appointed Adversary, and asks whether this is worth an eternity of looking over one’s shoulder. The Hero accepts the challenge. Kathool’s answering title, Eternal Sovereign, acknowledges the binding without ending the antagonism. Making it a god has constrained a threat by accepting a lasting relationship with it.
Kathool disappears from its former place and declares itself all around them: the depth of sea, mind and soul. It now considers Neso’s theft an invasion of its jurisdiction and promises consequences. The Hero believes this prevents further absorption and leaves a chance to talk Neso down. Kathool directs the Hero to the final obelisk, where another audience is waiting. The coronation has not restored what Neso already consumed.
The Final Obelisk
At the obelisk, Song mourns Noelle while a luminous figure resembling Aquella appears. The Hero asks whether Aquella had guided the search for truth or whether the voice was Kathool throughout. There is no spoken answer. The possibility that Aquella could communicate after her voice joined her ancestors remains a question the Hero cannot settle.
As the figure acts upon the Hero, Fa asks what she is doing. The Hero cannot hear Aquella, yet understands the message: Neso is about to step into Lore and claim it, and this is a one-way passage to the surface to face her. Xang declines an invitation to share that confrontation and elects to take the stairs. The scene gives the apparition a present purpose without explaining the origin of every earlier guiding voice.
Orpheus confirms Noelle’s life is extinguished and transfers the Head Researcher’s full access to Song. She is to return to the Midnight Zone with Dage and the remaining researchers to prepare Sparagmos’ offensive functions. Dage has called the Legion and expects other rulers to have noticed the commotion. The Hero leaves promising to carry the truth about the Elves to the surface rather than abandon them in the depths.
Neso’s declaration turns possession into a claim over the whole sea: the life it nurtures is hers to give and take. She refuses abandonment, humiliation and replacement, announces an Age of the Devouring Sea, and calls herself the Avatar of Water and Voice of the Sea. The Hero rejects that authority as the conduct of a leech taking what is not hers. The descent ends at a confrontation, with the stolen power and its consequences still to be faced.
A Good Beyond Forgiveness
Song’s optional Undine’s Dredge follows See You on the Other Side and is repeatable in the captured definition. Its small work contrasts with the attempted grand sacrifice: retrieve Noelle’s brooch, two Green Sea Jellies and one Elf Adipocere. Song wants to bring Noelle’s belongings home and gather remains that do not belong on the seafloor. She does not pretend that this repairs what Swordhaven has done, only that it need not make the place worse.
Noelle wanted to return home, and Song cannot leave her to rot. Aquella and the Elves also deserve release; Song considers the Sunlight Zone as a place for them to rest. The Queen’s choices and her own cannot be undone. What changes is her reason to continue: making others happy and safe can be enough even when forgiveness never comes. It is the answer to the conviction that had made death seem her only useful act.
Fa expects to spend a month or two repairing the transformed body in a dark corner of the labs, afraid the researchers will react with pitchforks. Even wanting Neso reduced to a puddle runs into the problem of an Elemental Avatar’s power and replacement. Fa also passes on an overheard report of Dage making a secret shield using his own pinky bones, interpreting it as some dark ritual. The shield’s purpose has not yet been explained to the Hero.
Other trouble has continued while the party descended. Mi and Tara are looking for Abel and Iseul; research and anti-undead prototypes are missing. Fa suspects Iseul used the Midnight Zone crisis to steal the books and hopes Abel is uninvolved. This is a suspicion, not a demonstrated theft or explanation of either disappearance. Xang, meanwhile, says she obtained her medicine and helped against Kathool. She plans to delay telling Drakath about the bargain while she and Xing pursue his birthplace and the surviving Court Magi for a cure.
Song also leaves the Hero a political duty. The Jus Divinum funded Undine and Swordhaven’s rebuilding after giving the murdered Elves’ Temple to Victoria. Only the Hero, she believes, can ask whether the Queen knew the truth or was kept in ignorance. As the new Head Researcher, Song can support the surface battle with Sparagmos; she also expects the Old Worlds’ Order to answer the Hero’s elevation of Kathool into a first crowned god. Survival has opened responsibilities that neither the descent nor the coronation resolves.
