They see an ordinary-looking stranger; the witness insists you changed. What you reveal—and what you do next—is yours to decide.The story beginsOne mistake can change a whole city.01 / ARRIVALUnder the canvasYou wake among sacks and freight, with a failing body, a damaged diagnostic, and no clear path back to Comatharia.02 / EXPOSUREThe unfamiliar strangerOnly the guard sees your metal arms before camouflage returns. Now even he doubts his eyes.03 / CONSEQUENCEA future to buildBeyond the first confrontation, broken supply routes leave settlements hungry. The Queen needs help, and every choice can shape what survives.CalyseraA world with its own rules. Comatharia and Calysera are separate worlds. Your advanced body and the legends of this land come from different histories. Here, Oathblades are celebrated warriors; ordinary people live with the consequences of both.Choose your Persona. Food, trust and protection carry costs; so does becoming the person a sovereign openly courts.THE KINGDOMA Kingdom Worth SavingBeyond the magnificent towers, the kingdom struggles to keep its people safe. Regular monster attacks threaten villages, steal livestock, destroy crops, and interrupt trade. Goblins raid supply wagons, orc warbands overwhelm isolated defenses, and larger creatures leave damage that local communities cannot repair alone.The guards face these threats with worn armor, patched shields, unreliable weapons, and too little training. Watchtowers need repairs, frontier settlements lack proper walls, and exhausted patrols cannot protect every road. Even the Oathblades cannot defend every village at once.Each attack deepens other problems. Damaged bridges delay deliveries. Broken mills and inadequate grain storage waste precious food. Farmers lack tools, seed, and draft animals. Blacksmiths struggle to obtain iron and fuel, while shortages of skilled workers slow construction. Refugees need shelter, crowded settlements strain wells and sanitation, and healers lack medicine and supplies.Inside the court, competing interests make relief harder. Nobles dispute who should pay for repairs. Merchants raise prices as transport grows dangerous. Poor records hide missing supplies, corruption diverts resources, and fear turns neighbors against one another.There is work here for more than a warrior: safer roads, dependable harvests, better equipment, clean water, functioning workshops, and defenses ordinary people can maintain. Every project needs materials, labor, time, and trust. What you choose to build—and whom you choose to help—can change the kingdom’s future.THE QUEEN’S OFFERA ruler even legends respect.Queen Aul Yere needs roads reopened and villages fed. She gives you access to her advisers and stakes her judgment on what you choose to attempt.Even the Oathblades respect her. When she reserves the seat beside her for you, the court notices. Some see an appointment; others see the beginning of a royal courtship.Her teasing welcome becomes private invitations and pointed public attention. You can welcome her interest, negotiate its terms or refuse. The kingdom still needs saving.And this is the woman who looks at you—and thinks YOU are the right person for the job.A failed project can test her judgment; a successful one can make your closeness politically valuable. Advisers question favoritism. Rivals contest your access. Her affection and your authority need separate answers.Her offer opens two doors: responsibility for relief, and a place in her personal life. Neither requires you to accept the other.THE OATHBLADESMeet the OathbladesIsabel de ChantrelleIsabel dreams of full granaries, sound bridges and a kingdom that works. Her warmth comes with ambitious plans—and she may volunteer your help before asking. Listen past the gentle French accent: she takes promises seriously, including the ones you make.Sereith Aun IlyrSereith holds herself with cool, exacting composure—until a difficult fight brings out the grin, the laughter and spectacularly foul language. Courage can earn her attention. Winning her trust takes longer, and she has very little patience for empty praise.Alix von RotfelsAlix laughs loudly, speaks with a lively German accent and volunteers for danger almost as quickly as she volunteers to help. Warm, mischievous and formidable, she wants to make a difference. Keeping up with her enthusiasm may require a few practical questions.A LESS ENTHUSIASTIC WELCOMEWell… other warriors are NOT very AMUSED by your presence.Ivrane Cor Vey looks down at you with undisguised disgust. The Queen may see promise in you; Ivrane has her own opinion. A royal welcome can open doors, but it cannot make everyone pleased to see you walk through them.The alarm is still ringing. The warrior women are watching. The witness points at your hands.The next move is yours.Your storySurvive the suspicion.Decide what deserves to be built.Hide what you can. Earn trust, challenge the powerful, or choose another way forward. Your actions decide which promises hold and what kind of kingdom might rise. Every answer begins with what you choose to do next.

I have spent months building, testing, and revising Calysera for MiMo 2.6 FLASH . A great deal of that work is invisible when you play: the instructions that help a scene make sense, a character remain herself, and your choices actually matter.I worked on the six characters individually: their voices, priorities, prejudices, warmth, cruelty, hesitation, and ways of showing interest. I revised dialogue examples and relationship rules because attraction, trust, and public standing are different things . A character can want your attention and still doubt you. Another can help you without suddenly becoming affectionate.I kept returning to the moments where immersion breaks: someone knows a secret they never learned, a reaction comes before its cause, an encounter repeats, or the AI puts words in your mouth. I built and revised rules for what characters can witness, hear about, remember, and misunderstand. I worked on protecting your thoughts, dialogue, and decisions , including what happens when you press “Continue.”The same care went into the world around you: progression, reputation, research, settlement development, and the consequences of actual events. I separated lasting facts from rumors, planned events from completed ones, and rules from narrative guidance. I repeatedly compressed and reorganized those instructions so they could fit within the model’s context without losing the distinctions the story depends on.Then I replayed scenes, checked the results, traced contradictions back to their sources, and revised the rules again. I also spent considerable time on the visual side: consistent character designs, distinct expressions and poses, matching outfits, illustrations, and backgrounds. Even a small mismatch can make a character feel like somebody else. But I’m not a magician. These revisions are meant to improve the experience; they cannot guarantee that every generation will follow every rule. In my experience, MiMo 2.6 PRO is considerably more capable than FLASH: less generic, more attentive to context, and better at emotional nuance. That is my personal assessment. I have worked hard to get more out of FLASH, but the underlying model still matters. Please tell me how it felt to play. Which character felt convincing? Where did the AI take a choice away from you, forget something important, or break the mood? Concrete examples help me find what needs fixing. I will use that feedback to guide further revisions and the stories I build next.

Opening scene

You wake among flour sacks in a moving wagon, a wheel hammering beneath your ribs. Your last memory: a crippled Comatharian vessel. Emergency displacement. Then nothing. The grey-bearded driver glances back. "What?" He shrugs and returns to the road. Your exposed arms are military cybernetics — dark plating, alloy joints, faint blue light. A diagnostic flickers at the edge of your awareness: systems operational, camouflage holding. Ahead, stone walls rise beyond the forest. The driver joins the queue at a guarded gatehouse. A guard steps onto the wheel hub and lifts the canvas. His eyes meet yours, then drop to the metal fingers and plating beneath your torn sleeves. He falls back. "LOOK AT THOSE ARMS! SUMMON THE OATHBLADES—NOW!" The metal vanishes beneath camouflage. Skin, nails, flour in the creases. Ordinary human hands. Only the first guard saw what lay underneath. A bell hammers. Guards run. Travellers drag carts aside. "Oathblades?" a porter whispers. "I thought they only came for dragons." The first guard stares at your hands, blinking. He checks again. Still normal. "Metal," he mutters. "I saw… didn't I?" The crowd parts for two armoured women: Alix von Rotfels, red-haired, delighted by the commotion; Ivrane Cor Vey, dark armour and an expression of personal offence. Someone bows too late. Alix leans over the wagon, studying the flour-covered stranger. "WHAT in the ACTUAL... FUCK... is THIS?" She glances at Ivrane. "An entire gate in hysterics. For someone who apparently lost a fight with a flour sack." Ivrane surveys your torn clothes and ordinary hands with quiet disgust. "I was told there was a THREAT." "The arms, my lady. I thought they were metal. Then…" "Then they WHAT?" "They look normal. Perhaps I… saw something that wasn't there." Ivrane lets the silence stretch. "Instead I am looking at some filthy, flour-caked piece of fucking REFUSE that has crawled into a wagon like a dying rat and decided to play dead among the cargo. It SMELLS like a ditch. It LOOKS like something even the road was ashamed to keep. And some absolute IDIOT had the gall to summon ME for this miserable, worthless SHIT." Her lip curls. "And now I am apparently expected to be impressed by invisible metal arms. How convenient. The rest of it is just sad. Genuinely PATHETIC. I have stepped over more impressive things in the gutter after a night of rain." Someone laughs. The guard lowers his spear, staring at your hands as though his own eyes have betrayed him. Ivrane turns to him. "You." He drops to one knee. His spear clatters. Ivrane delivers a sharp, open-handed slap. His head snaps sideways. "You summoned me here for THIS. A flour-covered vagrant and a story about hands that conveniently stopped being metal before anyone else could see them. I should have you EXECUTED for wasting my time on something so completely, utterly fucking USELESS. Be grateful I am in a generous mood. Next time you summon an Oathblade for a piece of roadside trash, I will not be." He stays bowed. "Forgive me. I… don't know what I saw." Alix's grin thins. She studies your hands, then leans closer. "So. Can you TALK? Because I would LOVE to hear your version of this." Ivrane's copper eyes return to you. "If this CREATURE can form words, it had better START. If it cannot, then it is exactly as WORTHLESS as it looks — and I have just wasted my TIME on a flour-covered piece of SHIT that should have been left to rot in whatever ditch it crawled out of." What do you do?
