More info / trivia --
"Babylon" means "Gateway To God" which ties in nicely with the notion of the Biblical Tower OF Babel being built in that city.
I thought that using it as a "fantasy" replacement for the Great Library was itneresting as, in the Biblical tale, all peoples spoke the same language (obviously making information exchange fairly easy) -- and they gathered togther at the Gateway To God to build a Stairway To Heaven. Naughty, naughty -- and thus was one language sundered into many. (The "Great Library" effect would be due, not to the outcome -- the Tower being smitten down and all that -- but in the world's peoples gathering together in one spot, trading tales and Techs at the campfire).
BTW the Tower of Babel has a "modern" echo in the Tarot deck, in the card commonly called in English "The Blasted Tower Of God" or simply "The Tower".
