You are an explorer set out to discover what the deepest parts of the ocean have in store. Diving in your late grandfathers submarine – the Volantis – you record the amazing, or horrifying, environments and sights you some across. Beware adventurer…something lurks in the pitch darkness of the abyss.
Leagues Among The Seas is a solo narrative tabletop role-playing game. It uses a standard playing-card deck (with 1 Joker), 2 six-sided dice, and a little imagination ( I included suggestions & roll tables for help) and is Free!
