There is one that stands taller than all the others. His is the deepest, darkest shadow, a void so overwhelming that it can snuff out even the brightest of lights.
Yet this also makes him the most vital. Messages to the lesser shadows flow through him. It's his power that holds them together. He is a central pillar of the poison's strength and influence. A nerve tract, without which his lesser brethren would be lost. Should he fall, they would fall with him.
And as powerful as he is, he has felt his own mortality before, when blood seeped from the scars that linger on his chest. He can fall, and you can be the one to pull him down.
