The Secret of Oki Island is a 5e solo adventure of swashbuckling action, open seas, and hidden treasure set in a world as whimsical as it is deadly.

A simple journey quickly becomes a search for a mysterious treasure with a motley crew of scallywags and scoundrels.

Through strength, skill, or charm you will have to survive the open seas alongside the pirates aboard The Rapier Wit and unravel the mystery of the egg that has chosen you to carry it home to a fabled fortune. 

Search the wide blue horizon for Oki Island and the riches it contains. But don't forget to get into some trouble along the way. The pirate's life is nothing if not exciting.

Pick your own path. Play your own 5e character. No DM, maps, or minis required.

We are making this for you if you want more of your favorite TTRPG and would rather play than DM yourself in the downtime between sessions. The Secret of Oki Island is designed for characters between levels 1 to 4. 

  •  Play your own 5e character. Made however you usually make one. The story is crafted so that all characters can succeed - or fail. 
  •  Take your own path through an interactive story where your decisions have consequences.
  •  Fight monsters, cast spells, and find treasure within an original story.
  •  Make progress with loot and experience that you keep in a regular tabletop game.
This version will include the PDF and EPUB versions of the adventure.

  • Explore islands, fight scoundrels, find treasures.

    Go on an epic journey to explore pirate towns and legendary islands. Swashbuckle your way through fights big and bigger to discover the untold riches every pirate hopes for.

  • Meet a motley crue of characters

    Travel the seas with assorted sailors and scoundrels. Will they help you or hinder you on your quest for The Secret of Oki Island?

  • What Is a Solo 5e Adventure?

    A solo 5e adventure is a single-person interactive story that uses the game mechanics of Dungeons & Dragons: 5th Edition.

    Create your own character to play as the hero of an original story:

    • Play your own 5e character made however you usually make one. The story is crafted so that all characters can succeed - or fail.
    • Take your own path through an interactive story where your decisions have consequences.
    • Fight monsters, cast spells, and find treasure. Make progress with loot and experience that you keep in your regular tabletop games.



    The experience allows players to be a lone hero solving problems and overcoming challenges without a DM or party.

    Each story is designed to work with existing D&D 5e games as either a downtime activity between sessions or a way to add flavor to a new character prior to their appearance.

  • How the Game Works

    As you take your journey through this solo adventure, you will have a chance to do all the things you probably love about TTRPGs, including rolling dice and choosing your own path through the adventure.

    • Interact with NPCs and your environment
    • Use your skills and abilities to overcome challenges
    • Cast spells, use magic items, and activate your class features
    • Fight monsters and other evil-doers


    All this works by following on-page prompts within the story and applying off-the-page effects to improve your character's chances of success. 


    The game mechanics will be familiar to anyone playing D&D 5e. From skill checks and saving throws to attack rolls and spell damage, everything about this solo adventure is designed to give you the same thrill as a session at DM's table but whenever you want to play.

    Plus, re-play the adventure to explore different options. Every choice you make in this solo adventure has some kind of consequence, so take each new character down their own path.

writing meh

I haven't finished it yet, but so far I'm not impressed. I'm a ways in and no fighting, and the writing is kind of off. Like I think stuff is meant to be funny, but it's just not. I liked the tone/pacing of your other adventures better.

Outstanding!

As a dedicated fan of Obvious Mimic’s D&D solo adventures, I’m thrilled to own their full collection, including the latest release, The Secret of Oki Island, and the upcoming The Mystery of Witchhaven, which I’ve already backed on Kickstarter. Each adventure in this series brings a fresh experience, making these books essential for solo D&D players.

The Wolves of Langston introduced me to their signature style—a gothic mystery that blends story, investigation, and combat. This adventure has great replay value, as choices impact the narrative, giving each playthrough a unique flavor.

The Crystals of Z’leth builds on that foundation with a survival-focused story set in an ancient, mysterious city. This adventure pushes players into strategic decision-making and exploration, enhanced by detailed artwork and a more intricate storyline.

The Secret of Oki Island has quickly become a favorite. Its high-seas adventure setting brings a swashbuckling twist, offering treasure hunting and pirate encounters that set it apart from the other books.

Looking ahead, The Mystery of Witchhaven promises to bring even more depth and mystery. Obvious Mimic has consistently shown they can adapt their stories to create immersive, engaging solo experiences, and I’m excited to see how Witchhaven adds to this growing collection.

These adventures are a must for anyone who loves D&D and wants a flexible way to play, delivering top-notch storytelling and gameplay that fits perfectly into a solo format.
