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.

Good times.

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.

As the Kabbalists sat in their secret covens and probed the worlds beyond the physical, the Summoners discovered four new planes of existence.  They drew pentacles and drew servants from…

Assiah, also known as Olam Asiyah, the weakest of the four spiritual realms.  The Realm of Action, the Nephilim easily invoke the creatures here and pull them forth to do their bidding.  This is the world of Korrigans, of Fairies, of Elementals, of Those who Creep and Nibble and Those who Inhabit the Sunset Homes.  Assiah is associated with the Tarot suit of the Pentacles.

Yetzirah, known as known as Olam Yetsirah, the World of Formation. Yetzirah is the Astral World, a plane of lesser devils and angelic servitors with glimmers of independent intelligence, elementals who embody concepts and creatures smart enough to bargain. These are the Princes of Salt Wisdom and the Spirits of the 24th Part of an Instant, those who stay until the day is favorable for their return. Yetzirah is associated with the Tarot suit of the Swords.

Briah, or Olam Beri’ah, the World of Creation, the planes of Heaven and Hell, the dwelling worlds of true Angels and Demons. They are cunning and wise and good and more evil than human comprehension. The Angels and Demons stand in their Choirs and bow before their Archangels. While the Angels and Demons hate one another, they hate Nephilim more, and do not stand to be summoned for trivial requests. They have full autonomy, full intelligence, and are difficult to control. Briah is associated with the Tarot suit of the Cups.

Atziluth or Olam Atzilut, is the World of Emanation. Atziluth is the dwelling place of the Arch Angels and the Demon Lords, of Gabriel and Beelzebub. They are proud and some have spent millennia worshipped as deities. These beings are the most dangerous of all to summon, for they greatly desire escape from their Pentagrams to walk the world of Men and they love to drag Nephilim slaves to their domains to serve them for eternity. The contracts with these beings are life-and-death pacts and drenched in blood. Atziluth is associated with the Tarot suit of the Wands.

Note: for those interested, Summoning is where Nephilim and In Nomine cross in super interesting ways, especially when it gets down to Contracts and Rupture. We’ll leave that exercise up to the reader for the time being. Suffice to say, one can assume In Nomine angels and demons can agree on one thing: they do not like these strange inhuman elemental endlessly incarnating abominations called Nephilim who can speak the forbidden Enochian tongue of Heaven and Hell and summon angels and demons to a Pentacle and force their bidding for a day short of a week.
