Cassan System

**Cassan** is an Imperial Dead World located in the Aeaean Cluster of Ultima Segmentum and most famous for being the Homeworld of the Scions of Cassan Adeptus Astartes Chapter. Formerly a Feudal World home to a sizeable population, the planet was invaded by a Ork Waaagh in 714.M36 and as a result suffered tremendous devastation. With the planet desolated and nigh on uninhabitable, it was decided to declare it a Dead World and the Scions of Cassan moved their Fortress-Monastery to their flagship, which was renamed the *Tears of Cassan*.

## Overview

The origins of Cassan are lost to time, with most records destroyed along with the planet. It is noted in the annals of the Aeaean League as a prosperous but primitive world, serving as a client state rather than a full member. A dynamic world of verdant forests and a blooming pre-industrial society, it was noted for producing excellent regiments of hardy soldiers.

## History

### Pre-Imperium

Little is known of Cassan's pre-Imperial history, beyond that it was incorporated into the Aeaean League. The league decided to keep the world in a primitive state, likely to better control the populace. Cassan was required to raise regiments in return for protection, with a number noted as fighting on Tvastar and Kharonea with distinction. With the fall of the league it was subsumed into the fledgling Aeaean Cluster and designated a Feudal World. For the inhabitants little changed, with one tithe being replaced with another and their governance remaining in the hands of an indigenous monarchy.

### Scions of Cassan

In M35, as part of the 18th Founding, Cassan was chosen to be the home of a new Adeptus Astartes Chapter, which was named the Scions of Cassan. The Scions maintained a distance from the main society of the world, remaining atop their mountain fasthold of Caerleon. Despite this distance they were regarded as godlike being by the rest of the populace, who gladly sent their sons to be raised to Astartes.

### Fall of Cassan

When the Ork Warboss Orkius Orkilius decided to invade the Scion's homeworld as part of his rampage through the Cluster, the consequences were dire. The majority of the Scions were present, having recent completed scouring operations to remove other Ork incursions in the Inoi SubSector. As the fleets clashed in orbit, thousands of greenskins descended to the surface in a myriad of craft and improvised pods. The Scions and the PDF put up a staunch defence, reaping a heavy toll upon the invaders. As the bodies stacked up and Orkilius became increasingly frustrated by the one sidedness of the combat and the imminent arrival of Imperial reinforcements, he hatched a plan to level the playing field.

The moon of Cassan, only lightly defended by an Imperial outpost, was stormed and a great mass of fusion engines were attached to the dark side. Orkilius launched the moon on a collision course with the Fortress-Monastery of the Scions, intending to completely destroy it, and thus break the stalemate. Unfortunately for the Scions and the citizens of Cassan, Orkilius greatly underestimated the destructive force that the moon (which possessed an extremely dense metallic core) would bring. The impact broke the crust of the planet and completely destabilised it, killing a significant amount of the Chapter, nearly the entirety of the planetary population and most of the invading Orks in a matter of minutes. Orkilius and the remnants of his Waaagh beat a hasty withdrawal as the vengeful vessels of the Chapter and battlefleet furiously charged them down, but the damage had been done. Cassan was a burning ball of devastation.

## Military

As a Feudal World, the PDF of Cassan was relatively poorly equipped, with predominantly pre-industrial technology at their disposal. Las-Locks that mimic the home built musketry have been provided by the Imperium to augment their firepower but access to more advanced equipment is restricted to avoid interfering with the population's development.

## Fortress-Monastery

The mountain stronghold of Caerleon was the former Fortress-Monastery of the Scions of Cassan, a formidable bastion with overlapping layers of defences. During the Ork invasion many thousands of Orks were slain attempting to storm the ramparts, cut down by the myriad defensive turrets and stalwart defenders. Sadly this stubborn resistance was the cause of the greenskins' ire and desperation when they forced the moon of Cassan to collide with the world. As the target of this attack, the mountain, and its defenders were completely obliterated.

## Climate & Geography

Cassan was a verdant world of expansive forests, similar to ancient Terra, with a number of oceans and continents. The human population spanned the entire planet, with a large number of coastal cities and swathes of farmland, aided by a mild climate.

## Politics & Culture

Cassan was an absolute monarchy, ruled by a high king who oversaw a number of lesser kings of the various smaller empires. The people existing in a state of Feudalism, subservient to local lords who provided land and protection in exchange for their goods. While pre-industrial, the people possessed advanced knowledge of metallurgy and stonework, able to produce large structures and primitive steam engines. Under the guidance of Imperial officials, they were able to replicate the Las-Locks of the PDF to the required standards with relative ease.
