Ultima Thule System
From Warhammer 40k - Lexicanum
The Ultima Thule System[1]
The Ultima Thule System is located within the Atroxia Subsector. It is a system with a major Cult Mechanicus presence, including the biggest Forge Worlds in the Caligari Sector.[1]
History
Ultima Thule was hit hard by a Tyranid invasion of Hive Fleet Garmr, which was beaten back by the legions of the Adeptus Mechanicus.[1]
Known Worlds
- Heliodor-II - Shrine World dedicated to Saint Basilus, who sacrificed his own life to protect the priceless treasures of the Grand Archives during a devastating Tyranid invasion. Within the labyrinthine tunnels of the capital there is a seperate, city-sized section that belongs to the Holy Ordos.[1a]
- Kobalt - Quarantined World that was once under the jurisdiction of Forge World Thule. The harsh climate and the huge deserts made it an ideal planet for the Adeptus Mechanicus to test their various engines of war. During the attack of the Tyranid Hive Fleet Garmr, the Cult Mechanicus launched their devastating counter-attacks without proper coordination, eventually burning the planet to cinders. [1b]
- Kosmas Maior - Death World with a population of 117 million. The strategic promethium fields and refineries located on the largest continent were attacked numerous times by the forces of Chaos after the confusion that followed the arrival of the Tyranid hive fleet. The Planetary Defence Force has so far managed to defend the key fortifications, which is of import to battlefleets operating in the subsector.[1c]
- Port Philon - Star Fort with a population of 460000 that is a bustling orbital dockyard under the jurisdiction of the Adeptus Mechanicus. The giant asteroid it orbits used to be a mining colony.[1d]
- Forge World Thule - Forge World of the Adeptus Mechanicus and the heart of industry of the Caligari Sector. It has a Production Grade of I-Secundi.[1e]
