The chronicles of Emerland. Solitaire. (Lite)

You will 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.

To defeat the dark forces in the battle you will have to visit the Kingdom of the Elves in a vast forest. You can climb mountains and find the Dwarves' holy place wandering through cave mazes.
