From Kickstarter:
The Vibrant Sea is a long-forgotten realm of mystery, wonders, and deep, dark secrets. Your character has found their way to the Vibrant Isle and will explore the Vibrant Sea around it. But will they and their friends be able to stop the darkness that threatens to destroy this wonderful place?
Secrets of the Vibrant Sea is a solo tabletop roleplaying game where you portray a character exploring a fantastical ocean. As you play the game, you'll improve your boat, improve yourself, and explore many dozens of the sea's beautiful wonders and murky caves.
And you'll meet the inhabitants who call the ocean their home.
This ocean is a mystical realm filled with the spirits of those who died seeking the magic of this place. Your character will join forces with locals to face these angry ghosts and stop their plans...plans that would destroy the island and lay waste to The Vibrant Sea.
