The Last Heir- Murder mystery and love story
A CROWN • A MURDER • FOUR MEN • ONE TRUTH
CAELORIA
THE LAST HEIR
─────── ◇ ───────
Some deaths are only the beginning.
THE STORY
You died.
Doctors. Voices. A monitor screaming somewhere beyond your fading consciousness. Then the unmistakable sound of a flatline.
Except death wasn't the end.
You awaken in Caeloria — a kingdom of ornate palaces, ancient bloodlines, political alliances, whispered scandals and secrets that have survived longer than some dynasties.
And somehow, everyone already knows your name.
You have awakened in the body of Caeloria's final royal heir — the very same heir whose mysterious death left the kingdom balancing dangerously between mourning, suspicion and succession.
To everyone around you, the changes in your memory, behavior and personality can be blamed on what happened.
You know better.
Fragments of another life linger inside this body. Memories that aren't yours. Faces you recognize without knowing why. Rooms that feel familiar. Warnings you don't remember receiving. Emotions attached to people you have never met.
Somewhere inside those broken memories is the answer to one very important question.
Who killed the Last Heir?
Unfortunately, surviving long enough to discover the truth may be considerably harder than dying the first time.
─────── ✦ ───────
THE KINGDOM OF CAELORIA
Caeloria is not just a backdrop for four romance routes. It is intended to feel like a living royal court.
Nobles, guards, servants, physicians, courtiers, informants, neighboring powers and hidden factions all exist within the world with their own histories, loyalties, ambitions and secrets.
Your story may take you through Bellamont Palace, the capital of Auremont, royal gardens, council chambers, libraries, training grounds, stables, restricted corridors, hidden passages, underground cells and places you may never discover during a particular playthrough.
Characters may know things you don't. Relationships may change which doors open for you. Evidence can become more or less meaningful depending on what you have already uncovered.
Something completely forgettable in one playthrough may become the clue that changes everything in another.
FOUR MEN
LOVERS • ALLIES • SUSPECTS • THREATS
Each man had his own relationship with the former heir — and each has his own reasons for wanting the truth buried or uncovered.
EVREN CAULDER
THE SWORN KNIGHT
White hair • Amber-brown eyes • Loyalty sharpened into a weapon
Disciplined, controlled and painfully loyal, Evren has built his entire life around duty. He was sworn to protect the heir once before.
Whether that makes him your safest ally or the man with the most to answer for is something you'll have to discover yourself.
──── ◇ ────
CASPIAN RELL
THE ROYAL BASTARD
Black hair • Warm amber eyes • Pleasure hides intentions
Charming, shameless and considerably more observant than he pretends to be, Caspian treats court politics like entertainment and danger like an invitation.
He laughs easily, flirts easier, and has spent his life learning exactly what people reveal when they underestimate him.
──── ◇ ────
THÉODORE AUVRAY
THE BETROTHED
Chestnut hair • Green eyes • Elegance concealing steel
Refined, politically powerful and accustomed to carrying responsibility without complaint, Théodore was promised to the heir before their death.
He knows the rules of court better than most people know themselves — and beneath all that composure is a man whose feelings may prove considerably less manageable.
──── ◇ ────
CORREN SAYE
THE MASTER OF WHISPERS
Violet hair • Bright blue eyes • Curiosity knows no bounds
Caeloria's keeper of secrets. Corren deals in information, observation and all the uncomfortable things people thought nobody noticed.
Quiet, beautiful and extremely difficult to fool, he knows the palace's hidden arteries better than almost anyone.
Discovering whether he is investigating you, protecting you, manipulating you, or simply fascinated by you may become its own mystery.
THIS BOT IS A GAME
Not every path is meant to end the same way.
The Last Heir was designed as a replayable romance murder mystery, not one linear roleplay with one predetermined route.
The world responds to your decisions, relationships, discoveries and the direction the model takes the story.
Investigate. Lie. Ask dangerous questions. Trust people you absolutely should not trust. Accuse the wrong person. Romance a suspect. Ignore a red flag so large it could qualify as royal architecture.
Your first playthrough is not the definitive version of events.
The man who becomes terrifying in one run may be the biggest sweetheart in your next. Someone who protects you once may betray you later. A character responsible for your downfall in one story is not guaranteed to fill that role when you return.
That is intentional.
Come back. Choose differently. Trust somebody else. Follow another clue. Take a different route through the palace. Fall in love with the wrong man again.
The goal is for returning to Caeloria to feel like stepping into another version of the mystery — not simply replaying the same story.
THE HEIR'S ARCHIVE
Your private in-world investigation interface.
The Archive is part of the game itself. As your story progresses it can track discoveries, residual memories, evidence, relationships, theories and other information uncovered during your investigation.
/archive — Open the Heir's Archive
/memories — Recovered residual memories
/evidence — Evidence discovered so far
/suspects — Current suspect information
/testimonies — Statements and accounts
/relationships — Relationship information
/theories — Investigation theories
/notifications — Archive notifications
/hints — Request investigative guidance
/commands — View available commands
/help — Archive assistance
/close — Close the Archive
The UI is still evolving and growing. New information, memories and discoveries may become available as your story develops.
RESIDUAL MEMORIES
The body you inherited remembers things you don't.
Certain places, conversations, people, objects or events may unlock fragmented memories belonging to the former heir.
These memories are pieces of the past. They are not commands, and they do not force your present-day character to repeat the choices of the person who lived in this body before you.
Some memories may answer questions.
Others may create much worse ones.
LOREBOOKS & WORLD GUIDES
The public lorebooks are there for anyone who wants to explore Caeloria beyond what fits on this page.
They contain additional world information, character references, locations, maps, visual guides and other material that may help during play.
I will continue opening appropriate lore material for pictures, visual references, guidance and additional world information.
The underlying game code will remain private.
I put a frankly unreasonable amount of work into teaching this thing how to misbehave correctly. ♡
AUTHOR'S NOTES
This bot was built and tested specifically using JLLM Plus. That is the model/version used while developing the game systems, mystery, character behavior and overall experience.
Regular JLLM can absolutely still be used.
Just be aware that it may lose details more easily during longer chats, simplify parts of the UI, forget pieces of the mystery, or become less consistent with complicated information.
Proxies are allowed.
Use whatever model or setup you personally enjoy. However, different models interpret prompts and formatting differently.
A proxy may alter or break parts of the Archive, memory system, mystery logic, formatting or other coded behavior.
If a third-party model grabs my carefully arranged murder mystery and throws it down the palace stairs, I cannot promise I can fix what it decided to do.
Proxy-related coding issues are use-at-your-own-risk.
DEAD DOVE
PLEASE READ BEFORE PLAYING
This bot carries a Dead Dove warning because it is an open-ended murder mystery using generative AI.
I control the setup, coding and opening message.
I do not control what the AI chooses to generate once your story begins.
Characters are intentionally capable of making dangerous, selfish, obsessive, cruel, manipulative or violent decisions depending on what occurs during your playthrough and what you trigger.
Yes — a love interest may hurt or even kill you.
That possibility is part of the game and does not mean the same character will behave that way in another playthrough.
POTENTIAL CONTENT / TRIGGER WARNINGS
Murder • Death • Blood • Violence • Attempted Murder • Poisoning • Injury • Threats • Captivity / Imprisonment • Political Manipulation • Betrayal • Deception • Grief • Trauma • Obsession • Possessiveness • Stalking / Surveillance Themes • Power Imbalances • Toxic Relationship Dynamics • Morally Gray Characters • Psychological Distress • Potentially Disturbing AI-Generated Behavior
Because generation is dynamic, no warning list can predict absolutely everything a model may introduce during an open-ended playthrough.
VISUALS
All character art, promotional images, locations, maps and other pictures used for this bot were AI-generated by me specifically for Caeloria: The Last Heir.
YOUR FIRST LIFE ENDED.
YOUR SECOND ONE IS A MYSTERY.
