Eidolon is a gaslamp fantasy setting, set in the year 1900. The characters represents the nobility of the era, mortals whose very flesh is quickened with the essence of stories. In this Realm, stories revolve around the nobility and their stately affairs. The eight great nations of the Literal Continent are all bounded under the sovereignty of the Imperium of Emperor Friedreich and his policy of Absolute Enlightenment. From the smallest domain to the greatest, the Imperium is a tapestry of politics; coloured by romance, intrigue, and vendetta. Travel, trade, and politics are hampered by the borders imposed by the bramblewoods, and not all domains have left the feudal era behind.
The Realm stands on a firmament of orderly ground, the largest gear in the celestial Orrery. Overhead, a great pendulum swings to cast the alternating lights of day and night. By night glimpses of these great celestial mechanisms can be seen in the aether. On the edges of the Imperium, the faerie border-marches seek independence from colonial rule, and underneath, the elemental kadmon pose a chthonic threat.
It is a Realm where electrodyne technology is forged by maddening alchemy and fuelled by dream stuff. Their inception has contrived much artifice to foster an age of wonder. We note that many modern conveniences are their direct consequence: the sexual revolutions of the 1860s were ushered in by modern contraceptives; the space race began of the 17th century, launched by Newton’s calculus, which opened the heavens to colonisation on Barsoom and Amtor; automata serve the elite; and the advent of imagery provides new forms of entertainment.
Thus, the Electrodyne Opera is the drama of politics, a game of thrones, and a work of blood and thunder. These are the romances and tragedies of nobility, both venal and exalted. It is competition for dramatic supremacy: to win the hearts and minds of the civilian audience; through adoration, through tyranny, through notoriety. It is the passion play of figures touched with dreams, destiny, and death; all seeking immortality and apotheosis.
Every noble has a story that resides within them that must be lived and told. Those whose tales are best remembered are those who achieve the greatest heights of power. They become archetypes of narrative, larger in memory than they ever were in life. The merest of nobles command the statecraft of diplomacy and the stagecraft of theatrics. The most sovereign of them have elevated themselves to stand amongst a pantheon of noble powers whose intrigues touch every corner of the Realm, and whose spectacle of dramatic interludes is the most beloved pageant of its people. Their whim and will are said to move heaven and earth themself.
It is the cusp of an era, evidenced by all too rapidly changing manners. The Oracle and the augurs of the Mousaion whisper worrying portents of the 20th Century, which presage the shadow of total war. The older generations cleave to mores of rarefied antiquity, whilst younger nobles embrace more avant garde vogues; to replicate manners of a bygone era with verisimilitude, or wholly redefine one’s self through innovative and popular culture.
Yet, amid the turbulent change, the Emperor and the other immortal Sovereign powers of the Imperium guide us on certain path to our manifest destiny. (from the book's introduction with permission of the Author).
