He fashioned heavenly stations for the great gods,
And set up constellations, the patterns of the stars.
He appointed the year, marked off divisions,
And set up three stars each for the twelve months.
After he had organized the year,
He established the heavenly station of Ne-beru to fix the stars' intervals.
That none should transgress or be slothful
He fixed the heavenly stations of Enlil and Ea with it.
Gates he opened on both sides,
And put strong bolts at the left and the right.
Core Gods and Beliefs
There is the Naharaim trinity of Anu, Bel, and Ea. Anu is the father of of Bel and Ea. Bel and Ea are depicted as either male or female or androgynous - their sex is unimportant and always in transit. Anu is the Sun, as the sun's rays are like the clear light of reason, Bel is Maths and Ea is Geometry, the two most important tools of a Naharaim philosopher.
Sprouting from Anu's head unbidden and fully grown was Imuru, who is Thought. Imuru thence ran from his family and flung himself into the Outer Void, which he copulated with and produced his children Substance and Accident.
From these (unchanging, as the Elven mind is long and slow to change) elements you derive the entire Naharaim pantheon. From Reason comes the world, and then the world produces the fruits of life and death.
But what is to be made of this, and how are the Naharaim affected?
To the Naharaim, Anu is unapproachable. As perfect reason is blinding and impossible to reach as the sun, so then the Naharaim turn to Bel and Ea. From Bel, they derived Maths, and so there is the study of the Divine Mathematics. From Ea, is derived Geometry, and so there is the study of the Divine Architecture.
It is clear, then, that from their religion is derived their most cherished cultural beliefs. The Naharaim are a scientific race, but they are a pious race, then, too, and all their efforts with brass, copper, and steam are so that they may approach the divine light of Anu.
Their machinery is maintained by the Order of the Bereshith and are considered holy relics. Though the Naharaim are not physically imposing, they would never dare to use their machinery in battle unless if it were for a righteous and distinctly religious cause.
The Hearts of Anu
Lastly, is their Enuma Eish. Their Hearts of Anu.
The Enuma Eish are moving temples. Whenever a Heart of Anu approaches a place of civilization a sacrifice is offered to it. This sacrifice is any person or an appendage of any person. Being sacrificed, in part or whole, to the Heart of Anu is not a desirable thing. A sacrifice to a Heart of Anu is a dreaded and feared thing to the Naharaim. The darker side of their society is revealed in this practice.
One enactment of their brutal laws with a sacrifice to a Heart of Anu as punishment can be seen in the following: "If the child of a courtesan or of a public woman come to know his father's house and despise his foster-parents and go to his father's house, they shall tear out his eyes and sacrifice them to the Enuma Eish, Heart of the Sun."
Indeed, having any body part of yourself being sacrificed to the Heart of Anu is akin to being damned forever. It is described in the holy text the Kufas Eish that to lose part of yourself to the Enuma Eish is to go:
To the house of gloom where dwelleth Irkalla,
To the house which one enters but nevermore leaveth,
On the way where there is no retracing of footsteps,
To the house which one enters, and daylight all ceases. "
It is said that those forced to give up a hand for theft, or a foot for cowardice, would rather remove these body parts preemptively and hide them so that they would not be dragged into the Naharaim version of Hell by their time of death.
The Naharaim sacrifice to the Enuma Eish is not a regular religious sacrifice to the gods, which is a beseechment for blessings. The sacrifice offered to the Enuma Eish is a sacrifice of the individual to society; enforcing on its people the idea and the memory of justice and good conduct.
The Hearts of Anu are many, and they wander the lands of Atoraya-Kaldea with a company of priests. An Enuma Eish is also present on any military battle, guarded by a cadre of the strongest brass machines the Naharaim have available.
Why the Naharaim should have such gross and crude contraptions (which they have invented and continue to propagate) alongside their more sublime beliefs about the ever-shining light of reason is a partial mystery. A primitive superstition, perhaps, is what encourages this brutal method of justice-keeping. But the great thinkers of Juraedon also recognize the taint of Gendûet's teachings, who was a teacher of the Society of Systems rather than the Society of the Individual. But the god's influence on the Eastern Elves has been covered before.
