=============THE SITH CODE=============A single, unifying code can be derived from Sith philosophy. The Jedi have a code, and we exiles know it well. But we also know it is full of inadequacies and half-truths.
The Sith Purebloods require no mantra to remind them how to live. They simply take what they can, kill what they don't need, and use everything to its fullest. They are ruled by the fittest and are a model of what the dark side can achieve.
There is knowledge to be gained from their example. If we were to create a Sith Code, it must point to the failings of Jedi beliefs while laying bare a path of mastery of the Force. It is plain that fear leads to anger, anger leads to hate, hatred leads to power, and power leads to victory. Rage channeled through anger is unstoppable.
The common edition of the Codex of Master Simikarty translates the Jedi Code thusly:
There is no emotion, there is peace.
There is no ignorance, there is knowledge.
There is no passion, there is serenity.
There is no chaos, there is harmony.
There is no death, there is the Force.
This Code confines its adherents. Peace, serenity, and harmony are restatements of the same thing―the passive acceptance of limitations. The Jedi encourage this.
But passion will always defeat peace. As we build our Empire here on Ziost, our successors will hold true to the Sith Code:
Peace is a lie. There is only passion.
Through passion I gain strength.
Through strength I gain power.
Through power I gain victory.
Through victory my chains are broken.
The Force shall free me.
