The five human senses are windows to perceiving the material world.
And the sixth sense—that mysterious and profound 'intuition' or 'premonition'—its origin is not at all illusory.
Its essence is a faint sensitivity to the gravitational effects produced by the Dark Matter and Dark Energy that permeate the universe, yet are difficult to observe through conventional means.
For most mortals, this sensitivity is passive, vague, and unconscious, much like living in a gravitational field without a precise awareness of gravity itself.
But at certain special moments, when the flow of Dark Energy or Dark Matter is violently disturbed by certain events, the "information" it carries can be passively projected into the subconscious of a perceptive individual via the medium of gravity, forming what is known as an "Omen" or a sudden insight.
Wizards, especially those of the Prophetic Series, take this a step further.
