Valroc: The Legend of Aquiny

The Legend of Aquiny is a cooperative, evolving campaign with 10 chapters. Two to four players can play as one of the four heroes and advance through the Adventure Book to solve the mystery of the Legend of Aquiny.

Each chapter requires you to achieve several objectives in order to succeed. If one of the objectives is not achieved, you will have to start the chapter again until you have achieved all the objectives in order to move on to the next one. Some chapters are in two parts. You will be invited to read the next section once you have achieved specific objectives.

The material is evolving! When you successfully achieve a chapter, you can open a new envelope to unlock new materials... and new rules!
The number of players can vary from one chapter to the next. So you can start the adventure with four players, move up to two, and finish the story with three.
