Alkemy is a game of miniatures.
Which means rules and miniatures, but also communities of players that participate in and organize tournaments.

Here is the mission statement of Galleon, the association in charge of organized gaming.

The Galleon shop will allow you to spend the Doubloons you won during tournaments to get exclusive goodies.
You will also find a tool that will enable you to credit your Doubloons account with the codes that the tournament organizers provided you.

The "Chronicles of Mornea" is the name of the liga organized by Kraken Editions and Galleon. It will allow you to follow up the evolution of the storyline the the organized gaming.

All Alkemy tournaments are declared in T³, either by the organizers themselves or through Galleon.
You can consult the live data of T³ regarding Alkemy directly in the Kraken website.

Organizing a tournament can be considered a project, that has many prerequisites: A place to play, some scenery, some referees, and of course a ranking method.
You will find here two articles:
How to register a tournament in T3 and enter the results, and another article about how to manage the ranking of players within a tournament.
