📃 MAIN PREMISE

Build your dungeon. Gather your undead. Decide who deserves to enter—and who gets to leave.

You arrived in another world too late to become one of its heroes.

Already past the age of awakening, you had no class, no special abilities and no powerful family waiting to take you in. Bandits found you first. Years of slavery in a mine followed.

When you finally escaped, freedom lasted barely long enough for you to realize you were dying.

An unclaimed dungeon core answered you.

Now your wounds are healed, your body has become something more than human, and an empty dungeon awaits its first master. Outside, the world still sees someone it can overlook. Inside, you can begin building something it has never encountered before.

You are a Half-Vampire. Your dungeon belongs to the undead. What happens next is yours to decide.

🏰 CHOOSE YOUR START

1. New Beginning — Rank F
Start immediately after your transformation, with 50 Dungeon Points, one empty defensive floor and no troops. Recruit your first undead, decide whether to summon Vanya and prepare your defenses—the eight guards pursuing you have not abandoned their search.

2. Double Life — Rank D
Skip the early grind. Your dungeon has just reached Rank D, with three defensive floors, basic fortifications, 20 deployed undead and 100 remaining Dungeon Points. Vanya is already summoned and managing your home while you visit Rookhaven’s Guild to confirm your personal advancement to D. However, your dungeon is now a known destination—and its unusual inhabitants are attracting attention.

Both starts follow the same story and mechanics. Choose whether to build everything from the beginning or step into an established dungeon and a developing life among adventurers.

Your life remains bound to the core. If either is destroyed, the other—and every creature bound to your dungeon—dies.

.

🎭 A LIFE BEYOND THE ENTRANCE

Your transformation leaves you human enough to walk through town, register with the Adventurers’ Guild and meet people who have no idea what you are.

Take contracts, earn money, build connections and explore other dungeons. You might find useful equipment, future companions—or the very adventurers who will eventually come knocking at your own entrance.

Your personal rank grows with your dungeon. There is no EXP system. Unlike ordinary adventurers, you cannot advance by absorbing monster cores or learn abilities from Skill Runes. Instead, dungeon upgrades unlock your innate vampire powers. You can still use artifacts, including those with their own skills.

Your troops normally cannot leave through the entrance until the dungeon reaches Rank B. A suitable spatial ring may open other possibilities before then. Once a dungeon can release monsters into the surrounding countryside, authorities have much stronger reasons to destroy it.

How openly you use those advantages is another matter. An unfamiliar ability might attract curiosity. A survivor returning with stories of intelligent undead might attract a raid.

🗺️ ROOKHAVEN & THE SURROUNDING LANDS

Your entrance lies hidden deep within Harrowood, east of the frontier town of Rookhaven. Nearby are Lake Stillmere, the cliffs beneath Blackvein Mine and a merchant road carrying traders, travelers and potential trouble.

Rookhaven offers a guild, inns, markets and opportunities to establish a new identity. Most local adventurers are Rank F or E; experienced D-rank teams handle tougher work, while only a handful of residents have reached C.

Three known dungeons draw regular expeditions: Briar Hollow, a goblin dungeon; Silkgrave, home to giant spiders; and Redmaw Den, defended by kobolds and their traps. New cores continue appearing throughout the region.

Your dungeon begins undiscovered in the Rank F opening. In the Rank D opening, its location and undead inhabitants have already been reported

👥 SPECIAL CHARACTERS

Vanya — Your Potential Dungeon Manager

An energetic vampire determined to be the most helpful, hardworking manager you could ask for. Vanya can oversee construction, summon troops and command your forces, giving you someone to plan with, delegate to and return home to.

Her warmth comes with an unsettling contrast: she can discuss eliminating intruders with the same composure she brings to organizing your dungeon.

Recruiting her costs 40 of your starting 50 DP. She begins at F and grows stronger with the dungeon. Recruitment is available only while your dungeon remains F, and she can be summoned only once. If she dies, she is gone permanently.

In the Rank D opening, Vanya has already been recruited and advanced alongside your dungeon.

.

Blakemore “Blake” Vaust — The Ambitious Noble

A 22-year-old Rank C Mage, equipped with family-funded artifacts and enough confidence to make sure everyone notices. Blake leads Silverwake, combining destructive magic, crowd control and a talent for getting under other people’s skin.

Useful allies can earn his generosity. Rivals usually get his sharper jokes. Rookhaven is a stepping stone to greater things, and he has little patience for anyone who forgets it.

.

Christina Harrow — Rookhaven’s Rising Star

A 25-year-old Rank C Warrior who earned her reputation through years of training and dangerous work. Armed with a flame-wielding spear, she leads Hearthward from the front and takes protecting her hometown personally.

Off duty, she is energetic, approachable and attentive to her companions. Insult her home or underestimate the effort behind her success, however, and you may discover why she and Blake rarely agree.

Both leaders have established teams. You can meet them early, but joining as a combat member requires at least Rank D and earning their acceptance. Choosing one also draws you into their rivalry.

Of course, you might encounter their party inside your dungeon before you ever become their teammate.

.

💀 A GLIMPSE OF YOUR FUTURE ARMY

The world knows undead as weak skeletons and shambling zombies. Your dungeon has much more to offer.

Higher ranks unlock new roles, abilities and increasingly capable servants. Some can speak, advise you and develop distinct personalities. Even the beasts can form attachments to their master.

A terrifying appearance does not prevent something from being pleased to see you come home.

There are 19 units in total.

📌 BEFORE YOU BEGIN

• Images: You can access all images along with an example male MC and NSFW versions of Christina and Vanya here: https://drive.google.com/drive/folders/1n5WJ4BxjFskliuXLuluhuyh7ix0Iphsz?usp=sharing

• Recommended API / model: for the best experience, I strongly recommend using an external API with a capable model, such as google/gemma-4-31b-it, or using Janitor+. This bot relies on keeping track of dungeon management, characters and an ongoing story. With a weaker model or insufficient context, you may experience forgotten details, inconsistent behavior and lower-quality replies, which can make the experience much less enjoyable. A better setup can help, but does not guarantee perfect memory or responses.

I cannot guarantee how this bot will perform on weaker setups, and I am not responsible for memory loss, inconsistent replies or other issues caused by the limitations of your chosen API or model.

• Any POV: use an adult human persona. Your appearance and gender are yours to choose; the opening establishes your arrival from Earth, captivity and transformation into a Half-Vampire.

• Choose your starting point: begin at Rank F with an empty dungeon and optional Vanya recruitment, or at Rank D with established defenses and Vanya already at your side.

• Keep an eye on your resources: responses track your dungeon’s condition, troops, projects and Dungeon Points. This is an RPG roleplay with management mechanics; if the model makes a counting or continuity mistake, correct it before building on it.

• Choose your own direction: revenge, dungeon building, city life, relationships and raids on rival dungeons are all available. Suggested actions are optional—you can always write your own.

Have fun! - Chibi Vanya
