You are the hero. The language is the plot
A story written for your level, in the language you are learning, where every decision is yours. Missions need equipment. Equipment costs coins. Coins come from one place only: studying.

Study to earn, play to spend
You cannot buy coins. The only way into the shop is through a class, a piece of writing, a review game, a word you mastered or a streak you kept going. The game gives your coins a purpose, and the coins give your study a reason to happen today instead of on Sunday.
A different book in every language
Japanese消えた氷の彫刻
A detective who hates the cold hunts a stolen ice sculpture in Sapporo, written from one sentence the learner typed.
SpanishEl Misterio de los Andes
You are looking for your grandfather’s house in Bogotá, and the Andes hold the answer.
FrenchLe Messager du Roi
A royal messenger rides through medieval France with a sealed letter.
Mandarin Chinese丝绸之路
A merchant sets out from Xi’an along the Silk Road.
Korean삼국 시대 전설
A legend from the age of the Three Kingdoms, where you meet the general.
Choose it, play it, keep it
An adventure is a story you make and then own. It takes as many classes as it takes, and it waits for you between them.
Choose your story
Pick one of the stories written for your language and your level, or describe your own idea and let it be written for you. A detective in Paris, a chef in Bologna, a biologist in the Amazon — or the one thing only you would think of.

Play it in the language
Each scene puts you in a situation and hands you a few options, all in the language you are learning. Some are riskier than others. Some need equipment you bought with coins. The story bends around what you choose, so it is never the same story twice.

Keep the book
When the story ends, it is yours: your own digital book, with images drawn for your scenes and an audiobook you can listen to again. It stays in your library, in the language you fought your way through it in.
It is also some of the best reading practice you will get, because you already care what happens next: read a chapter, listen to the same chapter as an audiobook, then tell your teacher about it in your next class.


You carry your progress on your back
Everything you finish goes into the backpack, and the backpack follows you across every language you study. Missions, souvenirs and achievements all count toward your rank. Start a new language and you do not start again from nothing.
Proof you were there
Every adventure leaves something behind. The souvenir chest is where those things live: the common ones you will find again, and the rare ones that were only available while a mission was open.


A guided tour disguised as a checklist
Before the adventure opens, you get your first missions. Finish a class. Submit a piece of writing and read the correction. Play a review game. Change your teacher's mood. Turn the subtitles on, then off. Each one hands you an item for your backpack, and the last one opens the door to the story.
Your first coins are waiting in your first class
Pick a language and start talking. The story opens once you have a few classes behind you.
