From the introduction:
Bells of War is designed to be the beginning of an epic campaign of Let Thrones Beware. The adventure introduces players to the concepts and mechanics used by the system. It also establishes Chael Hollow as the players’ home and base of operations for the first chapter of the campaign.
Ceyenus is a world in conflict, catastrophically damaged by Man’s incursion and destruction. So badly wounded is Ceyenus that the primordial forces of Trauma are ascendant. While they are not sentient beings, these malevolent forces exert powerful influence wherever good and righteous heroes seek to combat evil. Throughout the adventure, the decisions the heroes make will either feed the primordial forces of trauma, or bolster the forces of light.
When the heroes make choices that bolster the forces of light, the primordial forces of heroism may increase.
