From publisher blurb:
The Grand Stair stretches behind the scenes of the multiverse, the Doors upon its unfathomably vast span leading the way to gossamer worlds of limitless variety and infinite possibility. Human (and inhuman) civilizations in every conceivable variation populate these worlds, and on one shining world the race of man is ascending towards perfection.
Empyrea is an Earth-like paradise populated by the beautiful people of a technologically and genetically advanced Greco-Roman empire. Ruled by the deific Allfather, Empyrea is a place of superhuman Olympians, glorious competition, and hidden strife churning just below the surface. Gossamer Lords and Ladies beware - here, gods tread the ground and mere mortals aren't so mere.
