At one time, the Gods warred with the Primordials and nearly tore the very fabric of reality asunder. The mortal races, long used as pawns in this most violent of wars, rose up against their masters and put an end to the conflict, banishing the Gods and the Primordials both beyond the Material Plane. Years of research were put into magically binding these supernatural entities from interfering with the material plane – these years were reffered to as the Years of Binding. They culminated in a set of rituals performed by Humans, Dwarves, and Elves which generated what is now known as The Binding Accord. This powerful magic was used to lock the Gods and Primordials away from the Material Plane and to bind them from interfering with the Material reality without mortal consent.
In this way, slaves gained a measure of control over their former masters. For 10,000 years, the Gods and the Primordials both were forced into this accord with mortals, the laws of which were not to be broken, but the boundaries of which were constantly tested. Gods and Primordials were forced into cooperation; for the first time, lines were drawn in the sand, separating these entities by philosophical value instead of their cosmological source of power. Neither Gods nor Primordials could directly interfere in the works of the Material Plane without the help of a devout worshiper. This caused an unprecedented shift in cosmological priorities; suddenly, Orcus was no longer interested in unseating the Raven Queen, but interested in how he may circumvent the Binding Accord to wrest control of undeath in the Material Plane. Kord was no longer concerned with the glory of battle, but how to ensure that courage and bravery still proliferated throughout the mortal world despite his inability to interfere. And so on.
This shift in priorities likewise caused a shift in alliances. Corellon and Sehanine, historically enemies, found themselves in an easy alliance; their powers over of spring and autumn, respectively, maximized their influence over the wheel of time. The Raven Queen found herself to be the center of supernatural politics, and declared herself neutral in the battle for reality. Moradin and Bahamut discovered that even the gods on the side of good could not necessarily be trusted to uphold the spirit of a contract; recognizing each other’s respect for Law, the two drew up a detailed alliance, the letter and spirit of which neither has broken since. Despite their conflict of priorities – Bahamut focused on justice, Moradin focused on beauty – they have their backs covered. Regardless of the details of any given alliance, the rules set forth by the Binding Accord drive all Primordial and Divine behavior – if one knows nothing whatever about the personality of a God, one can be sure of her motives; to circumvent the Binding Accord and reassert control over Material Reality.
Magic, however, reflects those who utilize it; the magic of mortals has a lifespan, but the will of the supernatural is boundless. The strands of magic binding the Gods and the Primordials, so carefully woven, have begun to unravel. The rules have yet to be fully broken, but agents of the supernatural ever seek loopholes, and bend the rules with audacity unlike anything seen in millennia.
