Spheres of Influence

"With us you are ruler of all the Sith, answerable only to the Emperor himself."

- Darth Marr to Darth Nox

The Pyramids were at the centre of politics and power in the Sith Empire, each of the twelve Pyramids were headed by a member of the Dark Council, and between them they encompassed the entire Empire.

By the close of the Great Galactic War, with the seclusive withdrawal of the Emperor, this gave the Dark Council supreme and unchallenged authority throughout the Empire.

History
After the defeat of the Old Sith Empire in the Great Hyperspace War the Sith Emperor led the remnants into exile, with the intention of rebuilding the Empire and once again challenging the Galactic Republic. As the Empire rebuilt on Dromund Kaas the Emperor appointed a twelve member Dark Council who was granted the responsibility of ruling the Empire on his behalf.

Each Dark Council member took authority over a specific entity of the Empire, these included the military, Imperial Intelligence and the Sith Order. Power plays between the members of the Dark Council were constantly at work, at one point two members' rivalry was so great that they declared a Kaggath which pitted their two respective Pyramids against one another in a battle with great disgrace for the loser and great honor for the victor. After an intense duel destroyed the Dark Council chambers both Dark Councilors were subsequently executed by the rest of the Dark Council.

Other power bases
"A Sith cannot live without a power base"

- Darth Thanaton

Beneath each member of the Dark Council were many other Sith Lords whom each controlled power bases of their own, which included lesser Sith, soldiers and various other personnel of the Empire. The Sith Lords constantly vied to to increase their power and influence, utilising their power base to gain advantages over rivals, and in some cases killing these rivals and usurping control of their power base. An example being the downfall of Darth Skotia engineered by his archrival Darth Zash, who orchestrate his murder and at the behest of the Dark Council inherited his title and power base.
