Löwenheim

Discovery of Löwenheim
Not much is known on how the Crimsonmarines discovered the planet, it is said within the chapter that the Astronomican light flickered and teetered during their crusade causing the chapter to went adrift for some time until they reemerged into this unknown system.

The first writings regarding this mysterious planet were documents recorded by their pasts Bibliothekaren (Librarians) subjected to the planet's torment producing abilities towards Psykers and warp energy nullifying effects. Several reports of their explorations indicated a numerous amount of artifacts and relics dating back before even the age of strife (STCs) and a low population estimated to be around 10,500,000 divided into many tribes, all tribes seem to possess a great amount of knowledge on advanced and never before seen technologies. These findings of the chapters scouts only inspired more interest in this newfound star system.

Upon openly making their presence known to the tribes the Crimsonmarines adopted the native name of Löwenheim for the planet in their records. Having to make a decision between forcing the population into submission or simply cleansing the planet of all tribes, the Kapitel Meister (Chapter Master) took his most trusted brothers to go explore for one last time, needing more information to effectively base his decisions on.

Chapter Home World
The planet of Löwenheim, located in the star system dubbed by the Crimsonmarines with the same name as the Löwenheim System. The planet appears as a blue-green orb enveloped in a white web of clouds. Its surface has vast bodies of water and is covered in snow-capped mountains, with patches of green grassy hills beside the natural beauty of the planet, Löwenheim bears many scars from the battle against the Arch Heretic, uninhabitable Wastelands in the middle of rain forests, extreme deep craters surrounded by mountain ranges and coasts or beaches partly turned into glass. The planet is also well known for its warp negating capabilities making it one of the few safer places in the galaxy. Löwenheim also has many ruins and structural remains from both the Crimsonmarines "Cleansing" of the Xudeus and many still undiscovered ruins of the population's ancestors from the Dark Age of Technology. The many locations on Löwenheim covered with large amounts of ruins and remaining structures are called by the locals in the Löwenheim native tongue as Ruinenfelder translated roughly as ruin fields in which the tech-priests still explore and establish research outpost to study and perform experiments to this day.

The world of Löwenheim could be specified as a civilized world that has a wide range of societies and a high technology level, but unlike other civilized worlds, Löwenheim does not function as part of a larger Imperial sector. Without any trade links to other Imperial worlds outside the isolated parts near Löwenheim. Contact with other planets and people outside the Crimsonmarines sphere of Influence is relatively uncommon. The people of Löwenheim and other worlds that were pacified by the chapter mostly see themselves as loyal subjects of the greater Imperium.

The population of Löwenheim enjoys a reasonable standard of living (for the 41st Millennium!) but contrasting all other civilized worlds which are having societies where an infant is more or less guaranteed to reach maturity without becoming the prey to some ravening predatory beast or being enslaved by a rival tribe which makes them less suitable as a recruitment source for the Adeptus Astartes than any other world types, Löwenheim societies despite the vast technological knowledge inherited by the ancestral tribes are imbued by a strong warrior code inspired by the many generations of service, rigorously enforced by a ruling military elite. The worlds conquered by the Crimsonmarines are such regions of the Imperium, where despite a reasonable standard of living, every family dreams of having a son accepted into the ranks of the Crimsonmarines, and ensures they are trained to the utmost degree as soon as they are able to walk.

Löwenheim maintaining the most rigid military traditions that are likely to appeal to the Adeptus Astartes as a source for Aspirants. On Löwenheim and other worlds, the Crimsonmarines had conquered, the populations shape the very highest tier of a stratified and regimented society entirely focused on martial pursuits, where all aspire to the example set by the Adeptus Astartes of the Crimsonmarines. On Löwenheim the Chapter's Astartes and civilian staff are fully integrated into a wider system of tradition, obligation, and service. The Crimsonmarines have a strong influence on Löwenheim, unlike other chapters of the Adeptus Astartes the Crimsonmarines openly interfere with the directorates of the populations and play a great part in the planets governing body. This kind of authority is believed to have lasted since the times the Crimsonmarines have brought Löwenheim under Imperial rule after the times of the "Cleansing" which the various tribes began to ally with the chapter.

On Löwenheim, the main population centers tend to be large cities and urban environments based on a self-sufficient economy supported by the planet's own agricultural production. The state of development both technologically and socially varies depending on the region of the planet but mostly above the current Imperial norm. Most adjuncts of the Imperial state will normally have a presence on the planet. Löwenheim has an estimated population of around 15,700,000 slightly above the minimum of the classification guidelines of a civilized world by the Imperium of 15,000,000.

Eklipse - The Wasteland Moon
Löwenheim has four large moons The first is the smallest named Eklipse, an unhabitable moon without an atmosphere riddled with tunnels and craters. Remains of colonizations could be found on the moon, it is theorized to have once been an outpost in times of the age of technology many Terran millennia ago. Nowadays the Tech-priests who are assisting the Crimsonmarines had built a shipyard ring for void-ships to repair and maintain their optimal functioning capabilities of the many vessels in possession of the Crimsonmarines the size of the shipyard, however, does not support the building of void ships (only for repair and maintenance). The moon is tidally locked making it easy to locate the moon in situations of urgent needs for repairs.

Tide - The Aquatic Moon
The second is Tide, which is covered in vast amounts of water home to many sea serpents and other sea animals unpopulated due to the lack of landmass and from fear of the many aquatic predatorial animals inhabiting the moon. Even the moons core is presumed to be a solid form of water called Ice VII, instead of a core of molten metal like Löwenheim or any of the other moons. The moon has a habitable atmosphere supporting the existence of many unique animals from giant aquatic avians given the nickname "Fish Eagles" to deep-sea serpents so massive hypothesized to be able to wrap around the entire moon of Tide.

Staub - The "Red Moon"
The third moon Staub is also known as the "Red Moon" the Forge moon of the Crimsonmarines, producing vast numbers of weapons, vehicles and other advanced technology for the chapter and its war efforts. Staub is also the headquarters to the Adeptus Mechanicus who had assisted and accompanied the chapter since the times of their crusade. The moon is the center of their research and experiments which is one reason why travel to the Red Moon for Imperial personnel who are not members of the Mechanicus and share its peculiar faith is restricted not even Astartes of the Crimsonmarines are allowed except for a small number of Mechanikers (Tech Marines) of the chapter who are believed to have been granted allowance by the Omnissiah and are allowed to travel to Staub. This sacredness and secrecy of the cult are believed to be the reasons for the shipyard ring to have been constructed on Eklipse instead.

Knote - The Mountainous Blizzard Moon
Knote the fourth moon of Löwenheim the only place for the Psykers of the Crimsonmarines to live within the system without having to suffer the great torment caused by the Planet since all the other moons are not far enough for Psykers to live a normal life without the constant pain generated from Löwenheim. The moon might have a habitable atmosphere but the freezing temperatures and the very high mountains covering the entire moon are the reasons Knote does not have any settlers besides the Psykers. The Psykers of the chapter have built a massive keep called the Mondlicht fortress serving not only as the Crimsonmarines second base but also as the heart of the chapter's communication since all the Astropaths and Navigators could only have their resting places on this particular moon within the system. Its harsh conditions are some of the initial trials for the aspirants of the Crimsonmarines to be mastered.

Karlsburg
Prior to the construction of Karlsburg, the chapter had many headquarters spread all over Löwenheim for recruitment and housing the battle-ready warriors from both the Astartes and allying warriors while the Battle Barge functioned as their Fortress-Monastery the main base of operations during the times of the "Cleansing". Currently, the old headquarters on Löwenheim still serve as outposts for recruitment and vaults for weapons and armor while their other fortress on Knote, Mondlicht serves as the headquarters of all the Psykers of the Crimsonmarines, the Battle Barge functions as a mobile base in conquest outside of their territory.

The location the fortress is built upon was believed to be sacred by the many tribes prior to their unification by the Crimsonmarines, this place was believed to be a place where the mystical beasts in the tell tales of Löwenheim reside. This location is also the very same location where the Crimsonmarines had slain the Arch Heretic, naming the fortress after their missing chapter master honoring him after the battle, built during the relieving and expanding times by the succeding second chapter master Leon Kenner.

Only a great ceramite reinforced bridge surrounded by snow-capped mountains leads to the Fortress-monastery's great adamantium gate within the fortress walls. the halls within its marbled walls are heavily hung with a great wealth of trophies taken by the Crimsonmarines heroes from a thousand battlefields. The interior of the fortress contains flowing rivers running through the entire citadel from the nearby glaciers. Karlsburg is the spiritual home of the Crimsonmarines Chapter, and it is truly a formidable and magnificent sight to behold. Karlsburg is also built in a unique native architectural style of Löwenheim.

Like all Astartes fortress-monasteries, Karlsburg is armored and void-shielded to withstand any siege or bombardment that might befall it. Armed to repel attackers from land, air or space, its walls bristle with enough heavy ordnance to flatten a hive city. Every aerial approach to the fortress-monastery is overlooked by Icarus Pattern Lascannons and Macro-lasers known to the Crimsonmarines as the Zorns standing like spears of vengeance on top the high twin towers to lance space-borne enemies from the heavens.
