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.
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.
