@Tanshaydar:
I should definitely re-read it. I've got it in an anthology.
As a matter of fact I did not read any of those interviews. Any links would be greatly appreciated.

But I played the story of the game. And I still claim that the basic "codes" of occidental esoterism are here.
It's no big deal. I mean I'm not like "whoa I fond a super secret signification in the game". It's just that the story is deeply rooted in well attested historical truth about the beliefs of alchemists/occultists/wizzard/wathever.
I just mean that the story has a solid background, which in my point of view adds a lot to it.
Of course it's just a background, and I'm not saying it explains everything. There was not vitae collecting in mithraism, nor water lurkers
Weyer was basically a demonologist, and Agrippa turned his back to occultism in the end of his life.
But the reference to Mithra is here. Agrippa says that Weyer found his orb in a temple of Mithra. You can find his statue in the right room of the chancel. Remember that you have nothing to do in this room, just to watch the statue, altars and esoteric shit on the wall and pillars. This room his here just for the sake on ambiance and story, and unlock nothing. (In the editor, the statue is called "arabian statue")
I will re-read the novel. And if some of you mind you can read short articles about mithraism on the web site of David Ulansey (for example).
