Couldnt find anything in CP, but its all good. Just wanted to read what had been written before I made my own take on it.
IMC, Elans are the nefarious result of a greater scheme to destroy all magic.
(this is just the brainstorm, so if anyone reads this and wants to chip in, be my guest)
Basically, Asmodeus has deviced a plot to conquer the material plane (yeah, what's new?). He has allied himself with some immensely powerful mindflayers and created the Elan race. As they are "reborn", they think they are becoming the chosen children of the Creator, the only god (according to dogma all the gods other people worship are false gods, and powers acquired by worshipping them come from the devils/demons). The Creator bids his children to erradicate magic in the world, as magic is destroying it, causing the demons and devils of the lower planes to be able to freely enter the material plane. All these reborn have an aptitude for psionics (all Elans being wild talents, and with a high rate of psywars and psions, something that was almost gone from the world, because of the "class-ocide" that followed the mindflayers' attempt to extinguish the sun, around 500 years earlier). As the Elan army (called the Order) either peacefully or forcefully take over areas, more and more people are "converted" to the Creator, ie shipped off to a secret destination and changed to an Elan.
Now, obviously, this is a big bag of BS. Asmodeus plan is to wipe all spellcasters of the face of the earth, and thereby making it a much easier world to control, because lets face it, without spells, mankind is fairly SOL against the devils. Also the Order is fairly LE, although it professes differently, so that fits Asmodeus quite well too.
Obviously there is a number of ripoffs in there, but since none of my players have read the books etc, I have no problems doing that.
