Jacques de Aldersberg may have created the Church of the Eternal Fire, as well as the Order of the Flaming Rose?
In TW1 theres a log entry from a book on the Order that says Jacques took over the existing organisation with a mixture of righteous fervour, floral pyrotechnics, and Machiavellian scapegoating. To me the Church always seemed like an adjunct, a proselytising mission to the peasants in the locales of the Orders Barracks at best, they might be there to stoke tensions or just provide a non-militaristic front to the Order occasionally, but perhaps its all just a convenient cover for more nefarious business.
I just view the Order as a variant of any historical Military Order - those with a crusading nature anyway - and such things have manifested, and could manifest, around any belief system. I think its fair to say that ALL such historical entities would tend to be internally more authoritarian than their attached religion, and they all had a special focus that would be easily mistaken for zealotry by the uninitiated. The Templars themselves seem the obvious source, especially since their last Grand Master was called
Jacques de Molay.
Concerning the
Malleus Maleficarum and the phenomenon of the Witchhunts, consider the words of Irish folklorist Douglas Hyde:
"In most countries, for instance, the Devil is the great outstanding anthropomorphic conception added to the folk-lore of Europe by the introduction of Christianity; and later the belief in Witches, who trafficked directly or indirectly with the Evil One, became extraordinary prevalent and powerful. Now the most striking fact about the Irish collection is that the Devil personified rarely appears in it at all, and Witches never. The belief in Witches, and in Witches' Sabbaths, with which other nations were positively obsessed, and which gave rise to such hecatombs of unhappy victims in almost all the Protestant and in some of the Catholic countries in Europe, as well as in America, never found its way into native Ireland at all, or disturbed Gaelic sanity, although a few isolated instances occurred amongst the English settlers."
Btw: my gut feeling was that the Aen Seidhe don't have a religion as such, with named deities, services, and observances... every encounter with them says they are one with nature and therefore do not need structured religion. They seem to have a thing about Prophecy though, and historically it isn't required for Futurists to have a Pantheon.
And no goddess in her right mind would want worshipped by Dwarfs.
