From the introduction:
In this fantasy realm of living dungeons forged from the corpses of dragons, threats are in a constant state of flux. What adventurers have come to expect to be a troll may be very different from one dungeon to the next, as monsters tainted by the dragon’s viscera mutate over time. Heroes are needed to fight these threats, and to find the pearls and use them to heal the world.
Dragon’s Grave uses the Bids tabletop roleplaying game system. It’s an incredibly simple, highly narrative, diceless game system that gives players significant control over the story of their characters. These characters are often very powerful in their own right, wielding fabled relics, casting legendary spells, and capable of standing up to the minions of the gods, or even the gods themselves!
