The Ravage, a terrifying entity of flames, is heading into the heart of the forest of the dream world, determined to burn it to the ground.
You must stop him and his relentless army of fire elements. Place your last defenses (powerful water walls) in the best places. Use the unique powers of the animals that have come to defend their home. And don't forget to revitalize the forest by planting fantastic trees. To win the game you must protect the forest from Ravage cards. Each turn, four of these cards are revealed: some are flaming elementals, which threaten to set the forest on fire; others represent the Ravage's maneuvers, which are designed to strengthen his army or weaken the forest's defenders.
The elementals move inexorably toward the forest each turn. Throughout the game, you'll need to manage the cards you have as best you can, as each card must be paid for by discarding other cards from your hand.
Sylvion is presented to you in three successive levels: you start with a pre-built deck, and must manage these resources as best you can to counter the waves of relentless attackers. At the next level, you must build your own deck by choosing from a wider range of cards. Finally, two expansions included in the box will allow you to add new challenges and alternative victory conditions to your game experience.
