Enochian

And God said, “LET THERE BE LIGHT,” and there was light.

Enochian is the written and spoken language of beings of cosmic power. It is the language of the First Gods and the Heavenly Host. By a mutual compact adhered to by virtually all higher order cosmic beings, the very concept of Enochian is not shared with mortals. Among the New Gods, even, only the Primarchs have grasped the barest fundamentals of Enochian, and they are profoundly limited to those workings that adhere to their specific ideologies. Many godlings, even some Elder Gods, do not understand the full scope of Enochian except as it pertains to their specific portfolios of cosmic intention.

Every letter and sound is a hieroglyph or phoneme of staggering cosmic energy and geometric complexity that taps directly into the Power Cosmic to frame that energy into more specific constructs.

Few creatures are capable of channeling such energy. The intense effort required to hold a complex geometry in place as a mental construct is a tremendous limiting factor, even among those capable of focusing their will sufficiently to establish the framework. Those who can, however, use the Enochian language to redefine reality with every word from their mouth. Fortunately, the full knowledge of Enochian is largely guarded by the Archangels and curated by Heaven's record-keeper, Metatron.

Virtually every mortal culture with an affinity for magic has, over time, developed complex workings that vaguely emulate Enochian. But even among the Wise, very few understand the connection to Enochian or are even aware of it in a conceptual sense.

For an aspiring magus spellwork is going to be in a strange language and possibly require many peculiar components metaphysically related to the task at hand. It is often very idiosyncratic as well, derived from the trappings of culture it originated from. A Taoist monk might write complex calligraphy on sheets of white paper to summon a storm, while a shaman from the First Nations could call rain with a dance and ritual song. Both of these are attempts to emulate Enochian.

Compensating for mortal inadequacies causes the difficulty of spellcasting to increase exponentially with the scope thereof. Many become trapped in their own systems, unable to grasp the deeper concepts of the universe over the nuances of their own systems of magic. And because all mortal systems are inherently flawed compared to the perfect language of the universe, it becomes common even among the Wise to reach a point where their competence can take them no further.
