(Crowdfund Quest) Lair of the Rat Kings

Lair of the Rat Kings is the latest book for Onyx Path’s Realms of Pugmire - a tabletop roleplaying game set in a post-apocalyptic fantasy world thousands of years in the future after the disappearance of humanity. The players take on roles of uplifted dogs, and other intelligent creatures, who have built their own civilisation, explore lost ruins, and use leftover human technology that they mistakenly believe to be magic.

Most species within Realms of Pugmire define themselves by where they call home. The dogs of Pugmire protect their walled, feudal city. The Monarchies of Mau carry on the traditions of their houses and their intrigues, though they stand together against outside enemies. 

The rats and mice of the Realms of Pugmire make their homes in the margins of other cities. These connect to the Underneath, a vast maze of warrens, tunnels, caves, and other hidden places, much of which lies unknown and unexplored. It’s a dangerous place full of unexplained phenomena and terrifying creatures. But it is also full of wonders of ages past and the thrill of discovery.

Lair of the Rat Kings is a full campaign sourcebook detailing a new and exciting part of the realms of Pugmire: The Underneath. It contains not only everything you need to know about the Underneath, but also has information about making rodent player characters (along with their psychic powers), advice on how to run a subterranean campaign, a complete adventure, and a massive number of locations, set pieces, and encounters.

This book is a setting and adventure supplement for the Realms of Pugmire. That book contains rules for all the different things your characters might do and important information about the world they live in. The Lair of the Rat Kings takes us to new locations, with new intrigues and adventures, and new possibilities for your characters!

Complete character creation rules for mouse and rat player characters, including a new system detailing their unusual psionic powers
