In a magical and remote archipelago, a sorcerer helped by invading goblins enslaved the Goddess of the Island, generating discord between the 4 warrior tribes, responsible for protecting the island's temples.
Each tribe has magic crystals that can awaken a great warrior, capable of opening a magic portal and saving the Goddess, sending invaders to another dimension.
Now at war, the 4 tribes believe that only one of the tribes can save the fate of all.
In Portal, players use action points to move their warriors, seeking to collect diamonds from other tribes and take them to their own temples. For this, in addition to movement, players spend action points to acquire action cards, which allow special actions and even attacks against goblins and against warriors from other tribes.
Additionally, each time a diamond is taken to a temple, a random event is triggered, generating randomness with each new game.
The game is won by whoever manages to collect diamonds from all the other tribes, awakening their great warrior, and taking him to the ceremony site for opening the Portal.
