Thanks for sharing guys. I am aware of the separate development paths, but I'm prepared to go outside canon.
That said, where can I find more info about the things you've both mentioned? Can you point me to specific source-books?
Were there any heavily magic-oriented official campaigns/missions/adventures/whatever?
Also a new question:
We know that Horrors reside on some other metaplane (netherworlds?). Is it possible (no matter how improbable) that one of them Marks an Awaken metahuman (a PC actually) through some magic rift/crack with a corresponding huge magic spike (during a powerful ritual or some magic accident)? I'm thinking about centering one of the plot layers of my campaign around a PC trying to get rid of a Horror Mark (the Horror would only talk to him, but there would be a threat that in time it could do more). I'm already having fun when I think about the possible three-way conversations between the PC, his mentor spirit and the Horror. :-)
Now, I'm sure that Dragons and Immortal Elves will have all the magic know-how in 2075. Would the other players you've mentioned (corps, governments, secret societies, foundations) also have any clue about what a Horror Mark is? Or what a Horror is? Where would a Shadowrunner start looking for help?
Okaayyyy... lots here to talk about...
Originally (from what I have been able to piece together, and I can not support any of this as it is all convention table talk and what not) is that originally only the Immortal Elves and dragons were aware of the Horrors. Then somewhere into second/third edition they decided to drop the whole Horrors storyline in SR and drop all connection to ED. Rumors place this either as an argument about the direction to take ED and SR. Or, that the lead development line of SR was unhappy with the direction ED was taking things and the Horrors. Which is true (if either) is unknown.
The Horrors come from some meta-plane that requires an extremely high level of Mana to cross the bridge to our world. Now apparently the Horrors are not due back in our world for about 2000 more years (They show up at the peak of the mana cycle), However, the use of blood magic is schewing the level of mana needed.... and this is why Dunkie the Dragon blew himself up in his limo after winning the election in 2057. So he could stand on the bridge of the Horrors meta-plane and hold them back. (covered in the Dragon triology novels)
As for sourcebooks, Most of the are going to be 2 and 3e, and a couple of 4e...
Street magic (4e) has the 4e rules for most of those magical threats.
Threats (2e) (lots of magical baddies)
Threats 2 (3e) (some magical baddies)
Target: UCAS (3e?) (bugs!)
Bug City (2e) (bugs! Duh!)
System Shock (3e) (shedim)
System Failure (3e) (shedim, Winternight, little black lodge)
Wake of the Comet (3e) (shedim)
Year of the Comet (3e) (shedim)
