Deep within the heart of your campaign world lies a world without sunrise. Across hidden seas and shadowed shores, rival powers rise and fall beneath the gaze of ancient gods. The light of the Home Stone flickers in the distance, calling heroes, tyrants and wanderers alike to shape the fate of this primeval realm of dinosaurs and cavemen. In UMBROS, your campaign world will come alive with plots and possibility. Your players will take on the role of powerful faction leaders directing the march of armies, as well as lowly adventurers crawling in dark caves for fame and fortune.

The time has come to return to the Hollow Earth and cast off the shackles of conventional approaches to roleplaying games. The time has come to play in and run the campaign of your dreams. The time has come for UMBROS.
