Agathon, the Voice in the Darkness

The entity called Agathon has been transacting insidious arrangements with humans of western Immoren for centuries. Countless talented but impatient and greedy arcanists have been twisted to serve the Nonokrion Order as infernalists through the far-reaching schemes of Agathon. Though a creature of subtle power, will, and persuasion, Agathon is also a fierce battle master who takes delight in rendering lesser beings powerless and reminding them of their mortality. What those beings call magic is simple thought to Agathon, as reality bends and reshapes at a whim.
