The Destroyer Of Worlds: From the Akkadian Meditations

An advanced humanoid civilization resides in a protected realm known as Agartha and have existed on the Earth for millennia. Watching our progress as a species from afar, their ancient laws forbid them from intervening in our affairs. When the first atomic bomb is detonated, they choose to reveal themselves with an offer to share their technology on the condition that we forego our warlike ways. They choose James Forrestal, the first US Secretary of Defense as their emissary to deliver this message. But some in the government are skeptical of their message of peace, seeing nuclear weapons as our only protection against them. Set in the late 1940s, humankind stands at a crossroads as a civilization, should we join with the Agarthans and abandon our view of accepted history and cherished beliefs or is there an ulterior motive to their offer?
