The Immortal Legion Fleet serves the Korsumug Empire.

Description (Specifications)[edit]

The Immortal Legion Fleet is a large naval unit of the Korsumug Empire.

  • It is mainly equipped to TL–12 standards.

The standard of the Immortal Legion Fleet.

The Immortal Legion is hampered by the fact that it has no Class A Starports under its direct control - the repair and maintenance facilities at the newly upgraded Class A facility at Esmesli were destroyed by insurgents in 1099. The fleet is forced to cycle units to Velo, Hoddin, or more commonly Felspar in order to receive routine annual maintenance.

  • There is animosity toward the Glorious Triumph Fleet and Legion vessels within its territory may find themselves in conflict with forces under that units command.
  • The Naval Survey Office schedules unit operations and activities within both the Legion and the Glorious Triumph Fleet to minimize the chances of conflict.


The majority of the Fleets personnel are Jaibok.

  • A significant percentage of its officers, staff, and technicians are Jansa.
  • It has very few human personnel. Almost all are employed in administrative roles.

Tables of Organization (Organizational Structure)[edit]


A number of different squadrons and flotillas make up the Fleet. These are relatively hard to become a member of and they expect loyalty from their members. However, within the squadrons, rivalry is endemic and conflict is rife.

  • A Korsumug naval unit is never entirely ready for action: a percentage of its force will always be damaged or disabled as a result of internecine squabbles and attacks.
  • Ships cycle between the different units as they are sent for rest or repair or when they are assigned new duties.

History & Background (Dossier)[edit]

The Immortal Legion Fleet was formed in the late 1050s from various Korsumug forces located around Velo, an important naval base located in Mainsend Subsector of Mavuzog Sector. It was created with the intent of conquering the Siridor Trace, a then-independent region lying in the rimward half of Mavuzog Sector.

Around 1066 the Fleet, entirely consisting of the relatively small vessels normally operated by the Jaibok, struck into Siridor Subsector and took the Esmesli Drift, a small cluster of stars forming the trailing part of the Trace. Siridor went onto a war footing, ramped up ship production, and with Mavuzo support attempted to retake its lost member worlds. The Korsumug Empire fielded its new Malign class cruisers and Vermin class destroyers, resulting in a comprehensive Korsumug victory and the destruction of much of Siridor's naval power.

The Empire, however, seemed content with its new conquests and sat for over a decade, upgrading the port and constructing a major naval facility on Esmesli and building its strength. In 1079 it gained new leadership and Jaibok raiding increased significantly. In 1081 the fleet finally struck, launching the much feared invasion of Siridor itself, finally conquering the system after a heavy bombing campaign that resulted in millions of casualties as sealed habitats were blasted open. Within the next few years most of the other worlds of the Siridor Trace had also been taken. Resistance to the occupation was fanatical and the Jaibok have become embroiled in an ongoing insurgency determined to secure local autonomy.

Since then the Fleet has continued to occupy the area, conducting raids into enemy territory, defending against enemy strike forces, and patrolling the systems under its control. As well as fighting its enemies, factions within the fleet will occasionally "settle their differences" in full-blown battles involving dozens of ships.

Goals (Mission)[edit]

The Fleet, acting on behalf of the Empire, defends against the insurgencies, keeps the peace, guarantees interstellar trade, and inflicts harsh reprisals against wrong-doers. Resistance to Jaibok occupation within the region is continuous, with armed uprisings against Korsumug control receiving covert support, principally from the Principality of Mavuzo.

Fleet Admiral Garagh, the commander of the Fleet, is the Korsumug military governor.

  • The Immortal Legion Fleet is the ultimate representative of Korsumug authority in the region.
  • The Fleet is charged with retaining control of its designated area and conducting offensive operations against enemies.
  • A significant proportion of the Jaibok forces within the region are heavily committed just holding down those parts under their domination.

Raiding, patrolling, defense, and support are ongoing, with frequent clashes between the various sides.

Strategy & Doctrine (Operations)[edit]


Raids are long-range missions against enemy worlds. Raiders generally jump into a remote part of an enemy-controlled system, assemble at a pre-arranged rendezvous, and carry out refuelling. Once sufficient ships are ready they accelerate to their intended target, launch their attack, and then jump clear of danger.

  • Raids are conducted to damage or destroy merchant shipping, to disrupt commerce and industry, and to reduce enemy forces.
  • Some raids may land troops to carry out specific missions. These soldiers often have little chance of survival.
  • Successful raids earn the Jaibok crews spectacular glory and reputation.
