Note: I am slowly converting Nephilim, an old Chaosium game, over to Dresden Files FATE. I am just flopping all the posts on my blog because I can tag and collect them all later. This stuff is in no particular order. You can buy Nephilim in PDF from DriveThruRPG for ~$17. You should also buy Dresden Files RPG.
In the second decade after the Death of the Fool in Judea, a cluster of Nephilim of a highly Kabbalistic Jewish bent clustered around a single Nephilim named Simeon bar Yokkai. Clutched in this nigh-Agarthan Nephilim’s hands were the final scribblings of the Fool which told of worlds beyond the physical full of creatures waiting to be controlled and enslaved by Nephilim will. Only through chanting the right syllables in the right manner could the veils be pierced and a Nephilim could invoke a creature to come to its side. Simeon bar Yokkai called his application of Kabbalistic Theory Invocation.
When he passed beyond this world — by ascending to Agartha or simply passing on to a new Incarnation — his followers scrabbled through the dust of a Roman-dominated Levant and picked through the leavings of two thousand years. From lost scrolls found buried beneath Solomon’s Temple to the new Gnostic beliefs of Alexandria, they cobbled together a new magic they called Summoning and, much to their surprise, it worked. From their pentagrams scratched out in the dust, creatures emerged and demanded bargains and contracts for their services. The creatures came, and Nephilim conversant in Summoning found themselves more powerful than their Sorcerous brethren, for while a spell sword may last an hour, a summoned sword may last a week. And where Wahlsinn drives a man mad, the Powerful Pale Queen of Pain with Tears of Flame causes madness and unspeakable infinite torment.
In modern times, a summoner draws the pentacle on the ground to restrict the movements of the summoned creature. He chants the Invocation and calls to the creature in Enochian, the language of worlds beyond the veil. If the word reaches the creature, it appears and the test of wills begins. Some summonings are merely beasts or mindless apparitions, but some are full Angels and Demons with wills and plans of their own. Should the summoner win the contest, he forges a contract with the creature for a certain time — a day, a week, until the next full moon. But should the summoner fail the contest, the summoning ruptures and the angry summoned creature can enact its vengeance.
Summoners swear by their craft. These Nephilim abandoned the well-trod sorcery path to Agartha to reach into the nether realms to converse with beings of power, great and small, and harness that power to the Nephilim’s whims. Summoners claim the few known summonings of the Keys, the most powerful summonings, far outstrip the pedestrian castings of Grand Secret spells, but these summoned creatures are intelligent and malevolent in the extreme.
Nephilim summoning involves the four planes of metaphysical existence beyond the physical, the circles of summoning and the realms, the contracts, and the ruptures should summoning fail.
