In early days, at the end of the battle of the Valley of Sighs, the gods of dark, light, grey, and green met at the top of Mt. Doom. There they agreed not to manifest physically/directly – Proxy would be the way of battles – this was modelled on the way of the Celestine Powers on Helca. No more direct confrontation, no more direct interference. Little else is known of this, other than it has governed their interactions since. The accord allows for the deities to speak directly to their followers or against their enemies, but nothing else. It is a Sworn World Oath and is known as The Godspeak Accord.
The modern age is heavily defined by the clash of faiths in the “Affray of Darkness and Light” in which it plays a significant part.
The power of a divine Principle can be invoked by Connexion, to make a pronouncement of Weal or Woe, a Blessing or Onus, vision/dream revelation, an Observance of the sojourn or even a pronunciation of Agenthood in extreme circumstances.
To violate the Accord will break and stretch and bend the aether envelope that surrounds the planet of Helca itself. Divine principles will lose connection temporarily to their own sources of power – and banishment or death of a sorts becomes a genuine concern. They will be unable to provide their powers and knowledge to their followers. The breaking of oaths has serious effects including those of the gods. Their followers become vulnerable, their places of power become vulnerable, their items of power become vulnerable and this jeopardizes the mission of their followers and institutions. The breaking of such bonds carries with it a certainty that all those who have made the same bond know of the entity who breaks it. They are poised to take advantage of such an event. Elancil has some strange, limited capability of Violating the Godspeak Oath without repercussions.

General knowledge…
Mt. Doom was given its name at the time the accord was enacted.
Whenever the gods clashed directly, some terrible natural event happened elsewhere in the world. There would be nothing left of the world for the victor but a ruin. And so, the came together to form a pact, an accord between them.
The Celestials were not present when it was made, and have never agreed to abide by the agreement.
