They have black armor with a crimson trim and helmet, bear the golden Imperial Aquila on their chest, and have their right knee pad painted gold. Unlike their parent chapter, the Teuton Brotherhood does have a Fortress Monastery on the planet named Koein in the Teuton System. The Teuton Brotherhood have full control of the Teuton system making them both the guardians of the system as well as its rulers. They are a non-codex compliant chapter that have high numbers, favors the use of infantry and drop pod assaults, and have an affinity for close combat and siege/tunnel warfare. Unlike their parent chapter, the Brotherhood not only uses librarians but they have an abundance of them. They also are quite technologically savvy and are adept at naval engagements and boarding maneuvers. However, the Chapter suffers from a flaw in their geneseed, similar to that of the Thousand Sons, wherein the Librarians may suffer from uncontrollable mutation when they experience extreme joy, anger, or sadness, that turns them into Chaos spawn.

They seek perfection as well as mastery over anything they set their minds to. The Chapter is also obsessed with obtaining knowledge and have their own library filled with the books, tomes, scrolls, and fragments they have gathered. They don't discriminate when it comes to what kind of information they gather and will accept all forms of technological, philosophical, scientific, historic, and artistic knowledge. They are also desperately looking for a cure to their geneseed flaw, while also doing their best to hide it from all that are outside of the chapter, and hope that in their search of ever more knowledge that they can finally find a cure and become perfect Astartes.

They have a good relationship with the Adeptus Mechanicus and the Teuton Regiments due to a long history of cooperation. They are also close to the Black Templars and Imperial Fists. However, the Inquisition does not trust the Chapter nor do the Sisters of Battle and they have also had poor relations with the Minotaurs and Ultramarines Chapters.

 Motto/Battle Cry/Sayings: 

Motto: Perfection is what all children of the Emperor must strive for. For he is perfection incarnate.

Battle Cries: For the Primarch! For Purity! For Perfection! / For the Emperor! / Death to the unclean!

Sayings: We are the artisans of War. / Know thyself, thy ally, thy foe, and the battlefield. / One must understand the ways of the universe before one can hope to change it. / We are the Emperor's sons, it is not only our duty to defend mankind, but to enlighten it like he did.

 Home-World/System: 

The Teuton System is on the very fringes of the Cadian sector and is therefore affected by the warp. The Teuton system has 5 planets; Adule, Marien, Svjold, Koein, and Vera. Adule is a molten world that is uninhabitted with no moons. Marien in a dead world that has been experiencing a nuclear winter for 700 years and has no moons. Svjold is an agri-world with a population of 1 billion. It has one moon named Svjold Secundus that has been converted into a trade post/port. Koein is a hiveworld that has a population of 300 billion and has 3 moons, Koein Primus, Koein Secundus, and Koein Tirtius. Koein Primus has a Teuton Brotherhood battlestation/port encompassing it, where the Astartes fleet is docked. Koein Secundus is a port for Civilian usage much like Svjold Secundus. Koein Tritius is a Forge "World"/Moon under the jurisdiction of the Adeptus Mechanicus, for it is very rich in Ademantium and is an outpost for observing the destroyed Necron Tomb on Marien. Vera is a Frozen World that is inhabited by 1 million humans that have devolved into a tribal state and are constantly fighting each other, the elements, and the native Veran Wargs (Mutated Wolves). Vera has no moons.

Founding/Origins:

The official version of the Chapter's origins are that during the Third Founding, the Black Templars were given leave to create a new Chapter based on their recruiting world of Koein where they converted the Chapter Keep into a Fortress Monastery. Castellan Leon became the newly created chapter's Chapter Master and took his Fighting company and turned them into the first of the Teuton Brotherhood. The true version, is rather quite different. Even though the Brotherhood was "founded" during the Third Founding, this was not a legitimate Chapter ordered by the High Lords of Terra to be created. This was done in secret by the order of High Marshal Bohemond, using the Third Founding as a cover and false back story for this new Chapter.

The true origins of the Brotherhood come from an expeditionary force of the Black Templars discovering the system for the first time after following a chaos warband of Emperor's Children and a few Thousand sons sorcerers early in the 32 millennium. This expedition was under the command of Marshal Teuton and was tasked with finding this traitor warband and find out how they keep replenishing their numbers so quickly after incurring heavy casualties with loyalists during their raids. The expedition's hunt led the Crusade to the Teuton system in which they found the 5 planets. Marshal Teuton was cautious, for this system was not in imperial charts or records and he had no intel on what to expect. So he sent scouts out to the planets and kept his ships far out of the gravity well of the planets to avoid being detected. After a few weeks his scouts came back and reported the following. Adule was a hive world, Marien was a Forge World, Svjold was a medieval world, Koein was an world in the industrial phase of technology, and Vera was still a tribal world.

To Marshal Tueton's surprise, his scouts told him that they ran into an uncharted Traitor held system. For Adule was completely corrupted by Chaos and had a Traitor Fortress erected on the main Hive while Marien was in the hands of the Dark Mechanicum. The other three planets have been left untouched for they had no significance to the traitors. The Chaos fleet was docked above Adule, with one Battle Barge, one Retribution Class Battleship (heavily modified by the Dark Mechanicum), three Endeavor Class light cruisers, five frigates, and a number of gun boats. The Loyalist Expeditionary Fleet had one Battle Barge, one Vanguard Cruiser, 4 Siluria Class light cruisers, and two frigates. He had no idea how many Traitor Astartes were in the system and he knew the Dark Mechanicum had millions of skitarii, thousands of heavy armor assets and artillery, and possibly titans on their planet. He had three Fighting Companies of Black Templars (two in the Barge, one in the Cruiser), two Regiments of the Solar Auxilia (one light cruiser and the other spread throughout the frigates), and three regiments of Saturnine Hoplites (each in their own light cruiser). This meant that he had about 300 Astartes and 5,000 imperial guardsmen. The Marshal, realizing he had bit off more than he can chew, decided to call for aid from High Marshal Bohemond. In the mean time he planned to engage and destroy the Traitor fleet above Adule to cripple them and assault the planet afterwards. He would wait for reinforcements to arrive before trying to take on the Dark Mechanicum but would bombard the planet while he waited.

After a hard fought battle where the enemy had reinforcements enter the system as the battle raged and would use them to flank the Loyalists, the Templars were left with the Vanguard Cruiser and a captured Emperor class Battleship. The surviving count of Imperial troops was 131 Black Templars and 1,527 Imperial Guardsmen, wherein two of the three Castellans were slain and four of the five Regimental Commanders were also killed. After about a week of recuperating from their losses, preparing for the siege, and bombarding the planet with the Battleship and Cruiser, the invasion began and after about a month of grinding combat, the Loyalists suffered high casualties and realized they could not take the Fortress without reinforcements. Some 60 Black Templars were left and less than 700 guardsmen remained, Marshal Teuton was slain in personal combat with the Traitor Commander who had become a Champion of Slaanesh, leaving Castellan Leon in command. He ordered his forces back into the ships and to continue bombarding the planet until High Marshal Bohemond would come with reinforcements. After two weeks of bombardment it was discovered on the Emperor Class Battleship that there were virus bombs on board. Castellan Leon saw first hand the utter corruption of the plane below and believed that there was no redemption for those people, he ordered exterminatus on Adule and watched as all life on the planet was ravaged by the virus and then utterly annihilated by the firestorm that ensued. He was preparing to do the same with Marien until word arrived that a combined fleet of Mechanicus forces and Black Templars led by High Marshal Bohemond arrived. Just under half of the Chapter's strength, 500 Black Templars, had been deployed to reinforce the Expedition along with a Titan Legion, 10,000 Skitarii, and 4,000 Solar Auxilia. After 2 years of grueling combat, the remnants of the Dark Mechanicum were defeated and the system was finally brought under Imperial control but with high loyalist casualties.

High Marshal Bohemond was appalled by the losses incurred on the Loyalist forces in both the space battle and the sieges, but he was in a rage due to how the Traitors could be allowed to create such a foothold right on the Imperium's front door. He knew that a third founding was underway already but also knew that no Chapters were being stationed anywhere near the eye to patrol the area and ensure these events wouldn't occur again. He would have his Chapter keep sentinel over the area but it was not the Black Templar way for they were meant to be on an endless crusade. Castellan Leon proposed the idea that they make a new and secret Chapter to keep vigil over the sector, this Chapter would also be able to support the different Black Templar Crusades without the parent chapter having to divert its own forces from different fronts to aid a specific one. He also argued that the Mechanicum owed the Templars a debt for restoring a long lost Forge World to them and the repayment could be to remain silent about this new chapter as well as help arm it in exchange for the protection of Marien from Chaos incursion. After long deliberation, the High Marshal would agree and enter negotiations with the Mechanicus.

An agreement was reached in which the Forge World Marien would remain autonomous under Mechanicum rule as well as Koein Tritius and the Teuton Brotherhood (named in honor of the fallen Marshal) would have jurisdiction over Svjold, Svjold Secundus, Koein, Koein Primus, Koein Secundus, and Vera and ensuring the safety of Marien. Castellan Leon now would be the Chapter Master for it was both his idea and he has proven throughout his career that he was both a capable commander and warrior. He and the 60 remaining Astartes from the original expedition would be the first of the Teuton Brotherhood and they would use the geneseed of their fallen brothers as the geneseed for their new chapter. They would end up towing multiple wrecks from the Space battle and crash landing them onto the surface of Koein and creating a Fortress Monastery out of them with Mechanicum help. They would also keep the Emperor Class Battleship and make that their Capitol ship and keep the Vanguard Cruiser as well. Once Bohemond left, Chapter Master Leon would start his restructuring of the Chapter, reorganization, rearmament, and bolstering its forces.

Large quantities of bolters, heavy bolters, chainswords, mark III and IV power armor, bolt pistols, missile launchers, rhinos, lascanons, and predators would be produced in Marien and taken to the massive Fortress Monastery on Koein. Many other weapons and vehicles were being made as well but Astartes were being produced far too slowly in Leon's opinion and he demanded that reduced "production" times of Astartes be found. In the meantime, Leon had to figure out a way to make his tiny Chapter useful while it waited to get bigger, he decided to include the usage of librarians again in his Chapter and requested the aid of the Imperial Fists chief librarian to find psychically gifted Astartes and initiates and train them. Many initiates were found to be psychically touched along with some of the Astartes, including Leon himself. After about a decade of arming and training Astartes, the Chapter was 400 Astartes strong and boasted 20 librarians, Leon being Chief Librarian as well as Chapter Master. Also at the end of the decade, one of Leon's Captains found out the secrets of the mass production of Astartes from the Chief Librarian of the Imperial fists, using the methods of the Astartes Legions. After 2 years using the enhanced Astartes production, the Chapter was at full strength, 1,000 Astartes and they began to scour the Cadian sector en mass looking for any signs of the traitors.
