Ketrenia

**Ketrenia** was a terrestrial planet in the Cassiopeia Galaxy, covered in tall rock spires and forests. The planet was the homeworld of the Ketrenians and was an outpost colony of the United Cassiopeian Republic.

## Description

The planet Ketrenia was situated near the western border of the Lanh Sector, with the sector itself having been located in the eastern reaches of the galactic Central Expanse region. The planet orbited a yellow star and had five rocky moons of varying sizes.

The arid surface of Ketrenia was home to tall, sharp rock spires that resembled giant, flaky needles. Dense coniferous forests and freshwater lakes were also found on the planet. Ketrenia was believed to have a natural abundance in magical energy, which made magic-casting come more easily to some.

Ketrenia was used by the United Cassiopeian Republic as an outpost for the western border of the Lanh Sector. The UCR established Sinnertia Base to house the military personnel assigned to Lanh Sector border control.

### Government

Before the planet was annexed by the United Cassiopeian Republic, **city-states** governed different regions of Ketrenia. While some of these city-states made alliances with one another, others did not and existed as autonomous nations. At the head of these city-states were leaders called **Marshals**.

The **Ketrenian Parliament** served as the centralized planetary government of Ketrenia. This Parliament operated under the jurisdiction of the United Cassiopeian Republic.

## History

### Old Ketrenia: City-States

Long before the 6th millennium ASA, it was believed that Humans were the first settlers of Ketrenia. As generations passed, it was believed that Ketrenia's intrinsic magical properties affected Human genetics, which began to change and develop Humans into a distinct new species.

The native Ketrenians divided themselves into distinctive city-states. Over the course of Ketrenian history, city-states rose and fell, and allied themselves with each other and rivaled with each other. While wars between the city-states were fought, they were few and far between.

### Colonization: Roots in War

During the Cassiopeian Civil Wars, Ketrenia was annexed in order to serve as a base and stronghold for the Cassiopeian Military in the eastern Central Expanse. Ketrenia was one of several eastern Central Expanse worlds colonized for such a purpose, in order to defend the Inner and Outer Core Cassiopeian Republic worlds from Federation of Cassiopeian Star Systems attacks. The people of Ketrenia accepted the outside presence, at it seemed to bolster trade and commerce on their planet.

After the war had ended and the Cassiopeian Republic had been reformed into the United Cassiopeian Republic, Ketrenia continued to be used as a Republic outpost world. The war had unified the existing city-states of Ketrenia, allowing for the formation of a new parliamentary government that would adhere to the laws of the UCR. Ketrenia's outlander population grew after a need arose for housing soldiers who served on the eastern front, as well as for housing their families.

## Inhabitants

The inhabitants of Ketrenia referred to themselves as Ketrenians. This Ketrenian population included the native Ketrenian people as well as Humans and various other sentient species found throughout the galaxy. Native Ketrenians who practiced and wielded magic—which were most of them—were believed to have substantial control over clairvoyance, similarly to the Unoculans.
