Brave captain Jack has long plowed the sea on his famous frigate Black Dragon and never succumbed to the tricks of all mythical creatures. But one day his vigilance disappeared somewhere, when in the future there was a possibility to get a big jackpot and finish a pirate career with a rich man. The hero met a mermaid who told him about an island lost in the ocean, where untold wealth is stored, surpassing the resources of the Count of Monte Cristo. The captain bought himself into a fairy tale, and eventually ended up alone on an uninhabited island and without a ship. The sea fairy Minerva agreed to help the captain get out, but in return she asked to find several items and solve the riddles in Captain of the Black Dragon.
