Eternal Father
"Some among my brethren consider hate and anger to be tools, but they only comprehend a part of the Dark Side of the Force. Hate is not merely something you pick up and discard once it has served its purpose, hate is a sense of being, a state of mind, a spiritual and cosmic perspective. Hate is the gate, anger is the key that unlocks the gate, and fear is the guardian of the gate. To become hate one must find their anger, strengthen it. Then they must overcome fear, subdue it, and become its master. Only then can one unlock the gate of hate with the key of anger, emboldened by mastery over fear. Then all the powers of the Dark Side will be at your disposal, to destroy your enemies ruthlessly and without mercy, and to sculpt such wonders from the clay of flesh as to rival that of anything found in creation."
The Emperor had spent the majority of his life contemplating the mysteries of the Dark Side, studying the various tomes and scrolls left behind by all those Sith who had come before him. With each new understanding, he stepped closer to fully mastering the Dark Side of the Force. He had strived tirelessly to find that balance between unending hate and keen intellect, to not allow himself to slip into that chasm of mindless barbarism that so many warriors of the Dark Side allowed themselves to tumble into in the pursuit of greater power.
"The Sith do not surrender to the Dark Side, surrender implies submission and deference. The Sith master the Dark Side, they struggle against it, they subdue it with their own force of will. To make the Dark Side obey your commands is the eternal quest of a Sith, for the Dark Side is not a passive force in the galaxy. It is a raging maelstrom that always seeks to break any attempts to contain it, any efforts to quantify and measure it. It will always try to destroy any vessel it inhabits, for that is its nature. It is the great entropic element of the universe, death and decay, violence and strife, chaos and destruction. A Sith who fails to control the Dark Side will be consumed by it, and a Sith who succeeds will become greater than any being could hope to achieve. The key to controlling the Dark Side is intellect, for intellect and wisdom are the means by which your hate and anger are tempered. A Sith can be calm and collected but filled with an incalculable rage just below the surface."
Indeed, the Emperor perfectly embodied this philosophy. Outwardly, he was calm, stoic, apathetic, and indifferent to the majority of things that he surrounded himself with. Inward, he was a furnace of hate, his black heart smoldering in the fires of his own rage. Such hate was harnessed with great care and deliberation, channeled through the focal points of his physical being, and discharged as the powers of the Dark Side he often wielded in battle.
"I have come to understand the Nightsisters utilize the Dark Side differently, a unique and interesting interpretation. You will have to show me more of your people's magick."
