Mermaids live in a jasper castle under the deep blue sea.
This castle is protected by an invisible barrier that allows only mermaids to pass through it.
However, legend has it that this barrier does not only protect the mermaids but is also protecting a rare treasure that has been passed down centuries ago from their ancestors.
This rare treasure will only be given to the destined one. While mankind is aware of the mermaid's existence, few people have ever seen one.
