The passing of Jean did not mean the loss of his secrets. The Archangel of Lightning was a careful angel, and made certain that his research, his discoveries, his applications of theory were marked, recorded and properly filed in triplicate, with backup locations. Those few Orphans of Lightning too saddened to seek another's service aimlessly (and mournfully) maintained this treasure trove of accumulated knowledge for hundreds of years. Occasionally Raphael or Eli would come to consult Jean's notebooks and blackboards, but the Halls were otherwise avoided. The place was so neglected that Vapula didn't even have to kill anyone while absconding with his stolen prize.

When Soldekai came into his own, he changed all of this. He gathered up the Orphans of Lightning, and Inspired them to properly honor their beloved lost Superior. First came the Cataloging, which took a full decade (even with old Servitors come back to join in the task); but, by the end, every precious scrap of scientific and technological Truth had been found and prepared.

Next came the time of the Great Design. Servitors of Creation, Dreams, Divine Fire, Lightning, Steam, Stone and Wisdom gathered to plan a celestial Engine that could store and retrieve these Truths. They designed it to be accurate, swift and rugged: but they also designed it to be beautiful, clean and bright. They designed it to reflect everything that Jean must have wished to say about his Word, but never could.

And then they built it.

Today, most of the Halls of Progress is given over to hold THE Engine (to Servitors of Steam, there is only one THE Engine). Merely walking through the insides, watching the endless interplay of gears, wires, and obscure shapes of metal, wood and light is awe-inspiring: but the finest thing about this monument to Jean is that it is useful, as well as beautiful. Those honored with research rights may use one of THE Engine's many terminals and gather the knowledge they need to create their own Devices. There is even a set of 'public' terminals that any may use to gather common scientific knowledge - thus, even after his death, Jean continues to teach new Servitors about the subtle beauty of the physical universe.

But that is not the most astounding thing about THE Engine.

There is a secret known only to Soldekai and his most trusted Servitors. Some time after THE Engine was built, some of its regular operators noticed that there would be the occasional written reply that seemed a bit… odd. Certain researchers would find themselves receiving information that, while not requested, proved very helpful in their research. There were even cases where THE Engine seemed to have small parts of its design shifted overnight. Eventually, the Archangel of Steam, aided by some of Jean's wisest Servitors, searched through the design, trying to discover an answer… and finding one.

They call her Urania.
