Hi, I recently published a little RPG setting called Aauanautica. It was created as part of the Summer Lego RPG Setting Jam on the DIY & Dragons blog.
Aquanautica is a subaquatic sci-fi setting inspired by the Aquazone Lego sets from my childhood in the ‘90s. It takes place on Tethys-95, an oceanic, alien world filled with mystery and adventure. It was designed for use with tabletop roleplaying games but is system-agnostic and therefore doesn’t require any specific game system to play.
