From publisher blurb:
Finale and Free Will
The mastermind Nicodemus tried to foster enlightenment and empathy, to create the best of all possible worlds. After centuries of pursuing his grand design, however, the age of reason he dreamed of tastes like ashes. Chance, choice, and recalcitrant champions have stymied him, and so to achieve 'peace' he has turned to supernatural compulsion, a tyranny to which none can object.
But as the grinding gears of the Gyre draw the world toward its oblivion, people of every nation, culture, and creed yearn for liberation. Nicodemus need only complete a ritual at Axis Island to impose a thousand years of perfect obedience, but civilization has seen and rejected the future he offers. Though it may be their doom, they choose revolution.
An adventure for ambagious heroes of 20th level.
