The Sentinels of Baal were founded during the 13th founding, and as such, the Adeptus Terra has no gene-seed sample. The chapter was created after a reading of the Emperor's Tarot, though for what specific purpose is anyone's guess. May speculate that the Emperor foresaw the coming Occlusiad War, and that the Sentinels were created in response to it, since they participated quite extensively in the war. However, it has been noted many times since their creation the fervor with which the Sentinels pursue the Word Bearers Chaos Legion. One myth is that the chapter seeks revenge for the cause of their primarch's death.
The Sentinels of Baal are a fleet-based chapter, whose primary patrol centers around Baal and its moons. The chapter frequently recruits from various extremely hazardous worlds in the sector. The chapter's High Council have found, over the years, that such a pooling of genetic sources frequently provides the right mental and physical qualities required to become a Sentinel in the many Aspirants that live to become Initiates themselves. As such, the Sentinels' numbers have swelled well beyond the 1000-man limit instructed by the Codex Astartes.

The first major difference in the organization of the Sentinels of Baal is the number of Marines the chapter maintains. The high council keeps a minimum of fully half of the chapter's known forces to defend the fleet. The other half is constantly in various states of war; resupply and refit, transit, combat, and return. These are the chapter's initiated battle-brothers. What isn't reported or recorded are the many 'Training Crusades' that are constantly in progress. Each 'crusade' comprises four novice brothers under the tutelage of one seasoned brother. These seasoned instructors are traditionally chosen from among the entire chapter. However, it has become a more efficient custom to make the selection solely from those companies and squads currently with the fleet.
There are no real requirements for nomination to lead a Training Crusade, though many squads often nominate their best member, as the chance to lead a crusade is seen as a portent of favorble opportunities ahead. It is rare for a sergeant or other high-ranking battle-brother to be nominated, but when one it, it is usually by will of the council. And when the chapter master deigns to nominate a marine, all other nominations are withdrawn. Such tradition has seen many legendary heroes nominated, including Forgemaster Scipio Joerae, the Sentinels' current Master of the Forge, or Chapter Master <insert name here>.
Once an aspirant is chosen, goes through the process of being a scout, and becomes a full battle-brother, his performance is reviewed and his competence compared to the others. Groups of four are tailored together from the aspirants so that each group is as tactically balanced as possible. Once the groups have been made and are grouped together they are introduced to their new squad leader, the chosen Astartes. This squad is given a small band of ships and a few squads of Scouts and some menials, the essential equipment for their travels, and they are sent on a 10-year training 'crusade.' The four novices learn the various weapons, devices and systems they'll employ in their service in much higher detail than as a scout, while the Battle-Brother in charge of the new initiates learns how to better lead men.
These crusades are where each marine's individual disposition for a certain type of warfare comes from. The majority of the chapter prefer the brutal blur that is close, melee combat, like 1st Co. Chaplain, Captain. <insert name here>. Many others prefer the otherworldy roar produced by the use of melta weapons, while many gloves have had extra heat dissipation measures fitted to them, the heat from the Promethium-burning flamers intense from the near-constant use.
The next deviation is in the chapter's companies. Instead of the instructed composition, the battle companies contain more assault squads than tactical. However, the reserve and scout companies remain the same. In response, it seems, the Sentinels appear to experience higher instances of the Black Rage overcoming Brothers than would normally be expected. The Terran beauracracy is still trying to figure out how, despite such high numbers in the Death Company, the chapter remains at nominal strength.
Sanguinius via the Angels Sanguine
Oversensitive Occulobe: The Sentinels of Baal's geneseed has undergone some genetic mutation, causing their Occulobes to become extremely sensitive. This can be seen on the rare occasion that a Sentinel removes his helmet; his pupils are completely dilated, causing their eyes to look like pools of black surrounded by a sea of white. When a Sentinel does remove his helm, it is only in darker settings, such as their battle barge's dimly lit passageways, or under the night sky when they descend to a planet's surface to recruit.
Betcher's Gland Malfunction: Due to a malfunction in or related to the Betcher's Gland, the voices of the Sentinels of Baal have a very deep, resonant quality to them. While other Astartes find nothing out of place with the Sentinels' voices, common folks and various Xenos species find them to be disturbing, or even outright terrifying.
“For the Emperor, for Sanguinius, for Baal!”
The Sentinels of Baal have many various enemies and allies, though few enough of either are spoken of on a regular basis. The ones that are have helped shape who the chapter is now, and what it might be in the future.
Blood Angels and their successors: Although varied depending on the chapter, the Sentinels of Baal maintain at least decent relations with the Blood Angels and their successors.
Adeptus Mechanicus: It is well known that the Sentinels have close ties to the Adeptus Mechanicus; indeed, a larger number of Brothers are sent to mars to become Techmarines than the average chapter. This relationship has resulted in the immaculate care given to the chapter's equipment and vehicles. After every battle, numerous Techmarines begin painstakingly soothing the machine spirits of their charges. Another visible reward of a close relationship with the Mechanicum is the availability of various normally rare weapons. < as well as the chapter's noted use of higher quantities of rarer weapons and gear.
Word Bearers Chaos Legion: [i]The Sentinels of Baal have been noted, but have never outright confirmed, to be on constant lookout for the fleets of the Word Bearers Chaos Legion. Many sources speculate that the chapter has taken up the cause of defeating those who caused the Heresy initially, sort of as a punishment for what they did. Some of the chapter's fleet personnel have testified that they do have a special soreness with the Bearers, but nothing specific enough for certainty.
