From publisher description:
"Humankind was born in the seas and is now coming back here to survive" - Vulrick the mad.
The Polaris RPG is set in a far future where the world aboveground has become uninhabitable for the human species. Human beings have found refuge in the depths of the ocean, where they try to somehow survive in spite of the many difficulties they encounter in this hostile environment.
In this new world of silence and darkness, players can choose to become agents of one of the underwater factions, mercenaries working to keep afloat, or freelancers trying to establish their own communities.
All these elements and many others make up the backdrop of this universe in which one great mystery prevails: The Polaris Effect.
"According to an old Hegemonian saying, it is in the ocean's darkness that you can really measure the courage of a man..."
