The Pantheon was an underground organization intent on shaping the fate of the world, ostensibly for the betterment of mankind. It was formed by the mysterious figure known as Agamemnon, who claimed to be a living deity and father or direct ancestor to most of the Pantheon's chief operatives. It was eventually revealed Agamemnon was actually corrupt, and the immortal 16 year old son of the Asgardian, Loki.
