To defeat the dark forces in the battle you will have to visit the Kingdom of the Elves in a vast forest; climb mountains and find the Dwarves' holy place wandering through cave mazes; sink to the ocean depths to protect the Kingdom of the Mermaids from imminent destruction and to save the shrine of the Kingdom of the Humans from ruin.
When deciding to learn card magic in a school of an old wizard you could not imagine that you would be chosen by fate as a saviour of an entire world. Emerland is an ancient world of magic, where the fragile balance is threatened by the evil sorcerer Sat. Consolidate around you the races populating this fairy land: Elves, Humans, Dwarves and Mermaids. Only together you can challenge him!
