The Old Abyss Empire predates the rest of Creation as we know it. It was comprised a number of rocks of creation in the Abyss, some of which provided the foundations of the five Great Powers, while others have only recently been rediscovered.
The Succession of the Old Abyss Empire followed in an unbroken line from Father to Son as follows:
Justin the Stern, who set up the succession and demanded sons be the successors only.
Theodosius the Clever, who maintained the succession but allowed the succession of second generation sons through the female line like France instead of the Holy Roman Empire.
Valentinian the Conquerer, who was too busy conquering everything he could find to work on much else. He had a habit of throwing lavish triumphs. During his reign, the twenty-six large Rocks of Creation of the ‘Brownwater’ Empire were on verge of collapse, was he was looking at ‘Bluewater’ abyss conquests.
Cornelius the Elder or Consolidator, who ended up too busy consolidating the twenty-six major Rocks, and tens of thousands of minor ones, to ensure that there was a government that had common elements while respecting local traditions and autonomy.
Cornelius the Younger (Cornelius the Great), began the transition to ‘solidify the abyss space’ between major rocks. Died with the work half-finished. Thirteen of the twenty-six rocks were incorporated into “Shadow”. He moved his capital to Thelbane, and separated the thrones of Thelbane and the Old Empire. The thirteen territories in the abyss were depopulated and subject to repeated calamity.
Swayville the Great, who holds the twin titles of King of Thelbane and Emperor of the Black Zone; and titular Emperor of the Old Abyss Empire.
