765.M41:  Chapter Losses to date:  13 Lost in warp, 21 Irrecoverable battle losses, 9 Gene seed failure, 4 Inquisitorial purge, 16

There have reportedly been 26 foundings so far.
M31- FIRST- PROGENITOR.   (?)-    Legions made up from gene seed samples of the primarchs, even while primarchs scattered and undiscovered.
M31- SECOND- PRIMOGENITOR.  (30,021)- Legions split up into chapters.  It is unclear whether new chapters were built up from gene seed as well.
????- THIRTEENTH- DARK FOUNDING.  Unknown number or fate of chapters.
M36? TWENTY-FIRST.  Known as the Cursed Founding.  Occurs shortly before the age of apostasy (which was in early M36).
M41- (40, 736)- TWENTY-SIXTH.
Astartes Praeses- a group of 20 chapters formed with the express purpose of of guarding the Eye of Terror.

    According to 2nd edition background,  9 of the Primarchs "survived" the Horus Heresy- the rest died or fled into the Eye of Terror.   We know that Sanguinius and Horus died.   We also know (as of WD 261) that Ferrus Manus is presumed dead at Isstvan V (though his body may have been recovered and taken to Mars). We know that Guilliman, Jonson, Khan, Russ, Dorn, Vulkan, and Corax survived (especially since they are mentioned in the most recent Black Templars background).    That  makes 7 loyal primarchs.  The other two could be those from the deleted records (the 2nd and 11th legions).    The more likely possibility is that Konrad Curze and Alpharius count as survivors, as they did not become Daemon Princes nor were they killed until AFTER the heresy.
    Note also that the 2nd edition background indicates that of those 9 primarchs, all of them had died (or disappeared?) after 1400 years (of being  created, presumably).  Their remains have since become relics, particularly the tomb of Roboute Guilliman.  Rumours exist of the possibility that Lemann Russ, Ferrus Manus, Corax, and Lion El' Jonson will return some day, of course...
   Six of the Traitor Primarchs have gone on to become Daemon Princes (Fulgrim, Angron, Mortarion, Magnus the Red, Perturabo, Lorgar).  Konrad Curze is confirmed dead (by an Assassin) according to background in the 2nd Edition Chaos codex and the 3rd edition Assassin codex, though he was killed after the heresy, not during.  The IA article on the Alpha Legion settles the fate of Alpharius- killed in single combat by Roboute Guilliman after the Horus Heresy.  Guilliman was in turn killed by the daemon prince Fulgrim, long after the heresy was over.
Killed during Horus Heresy Loyalists that Survived Heresy Killed after  Heresy Daemon Princes Missing
Sanguinius, Horus, (Ferrus Manus) Guilliman, Jonson, Khan, Russ, Dorn, Vulkan, and Corax Curze, Alpharius, Guilliman Fulgrim, Angron, Mortarion, Magnus the Red, Perturabo, Lorgar Jonson, Khan, Russ, Manus, Vulkan, Corax

According to various backgrounds (which all agree on this point), Horus had Five Legions that had sided with him (and against the Emperor) before the Isstvan V event.  Seven legions were sent against him at Isstvan V- Four of which changed sides and joined Horus (referred to most recently in the second printing of the 3rd Edition Codex Chaos Space Marines, and the Index Astartes: Raven Guard- WD 275 p.101), the other Three of which were destroyed (more on that later).

Legion #11

According to IA: Word Bearers (WD 269 p.113), the Word Bearers were the first legion to be corrupted by Chaos.    The Night Lords are stated to have gone renegade before the Horus Heresy even broke out.  The Word Bearers were already followers of Chaos before officially joining Horus, and had also sent a massive force against the Ultramarines homeworlds around this time.  The Emperor's Children were reportedly corrupted by Horus when they were sent to bargain for peace right before the conflict.   The Iron Warriors themselves are specifically said to turn at Isstvan V. The only conflict with the information above is the turning of the World Eaters, whom Horus was sent to subdue before Isstvan V, and he recruits them instead.  It seems unlikely that anyone would send the World Eaters to subdue Horus after they had previously sent Horus to subdue the World Eaters.

With the advent of Decipher's Horus Heresy CCG (and corresponding art book), some of the classic background surrounding Horus and the legions has been brought back into light (though it appears to conflict with the background from the Index Astartes articles on some points).  In summary, Horus was wounded on Davin and tended to by the warrior lodges there, who converted Horus to the worship of Chaos.  Horus then had marines from the Emperor's children, World Eaters, and Death Guard inducted into these warrior lodges.  When Horus and these three legions were sent to subdue a tyrant on Isstvan III, Horus and the other corrupted primarchs agreed to eliminate the marines in their legions known to still be loyal to the Emperor.  The loyalists were sent to subdue the planet, and after they succeeded, the traitor ships virus bombed Isstvan III.  It did not kill all the loyalist marines though, and a handful of Emperor's Children, World Eaters, and Death Guard loyalists were still on board the orbiting ships.  Led by Captain Garro of the Death Guard, these loyalists escaped on the frigate Eisenstein to  warn the Emperor of this betrayal.  Some of the loyal Emperor's Children marines (led by captain Tarvitz I believe)  made their way to the planet surface in a Thunderhawk, to tell their suriviving brethren of the betrayal.  A bloody fight ensued over the wasted ruins of Isstvan III when the traitors dropped to the planet to wipe out their loyalist brothers.  The Isstvan III massacres were the first (and possibly last) time marines of the same Legion fought on both sides of a conflict.

The Index Astartes articles name these legions, nullifying my original assumption that two of the three Legions destroyed at Isstvan V are the ones Deleted from Records (Number 2 and 11).  In the Iron Hands IA article (WD 261), it is clearly stated that Ferrus Manus and his veterans spearheaded the attack on Horus' forces along with 2 other Legions (and later refers to the Salamanders and Raven Guard legions).   This information is confirmed in the Raven Guard IA (WD 275, p.99).
    Since only a small force of  Iron Hands could get to Isstvan V in time, the rest of the Legion survived the massacre, carrying on to this day and yielding successor chapters even though Ferrus Manus was killed in the conflict.   The Salamanders continue on (though they have no known successor chapters!)-  Vulkan survived the heresy according to the background in Codex: Armageddon (under the Black Templars of all places), so it was possible for the Salamanders to be built back up from almost nothing if need be.  The Raven Guard Legion was shattered, but Corax survived, and resorted to accelerated Zygote development only to create monsters which were never spoken of.  The Raven Guard operated in small squads behind enemy lines until they could finally build up their forces again, nearly a century after the end of the Horus Heresy.  They also welcomed the Index Astartes principle of breaking up the legions, forming 3 successor chapters.

In addition to chemical treatment, hypnotherapy, and training, nineteen organs were developed during the original creation of the superhuman breed known as Space Marines.  Over the millenia, some chapters have lost some of these organs to geneseed flaw or other issues.  The presence (and deterioration) of some of these organs defines some space marine chapters.

1.  Secondary Heart. The secondary heart is capable of boosting the blood supply or maintaining full life functions even with the destruction of the recipients original heart. The phase 1 implant enables Marines to survive low oxygen concentrations and traumatic injury.

2.  Ossmodula. This is a small sized tubular shaped organ. The Ossmodula monitors and secretes hormones affecting epiphyseal fusion and ossification of the skeleton. At the same time, the specially engineered hormones encourage the forming bones to absorb ceramic based chemicals administered in the Marines diet. Two years following implantation, this will have caused considerable strengthening of the long-bones; extreme ossification of the chest cavity (caused by growth of the ribs forming a solid mass of inter-laced bone plates) and a general increase in the size of the recipients skeleton.

3.  Biscopea. This organ is implanted into the chest cavity. It is small, approximately circular and, like the Ossmodula its primary action is hormonal to stimulate muscle growth throughout the body.

4.  Haemastamen. This tiny organ is implanted into a main blood vessel. The Haemastamen serves two purposes. It monitors and to some degree controls the phase 2 and 3 implants. The organ also alters the constituent make-up of the recipients blood. As a result, Marine blood is considerably more efficient than ordinary human blood, as it has to be when you consider the extra biological hardware a Marine carries inside him.

5.  Larraman Organ. This is a liver shaped, dark, fleshy organ about the size of a golf ball. It is implanted into the chest cavity along with a complicated array of blood vessels. The organ generates and stores special Larraman cells. If the recipient is wounded, these cells are released into the blood stream. They are transported to the site of a wound. Once in contact with air, the Larraman cells form a skin substitute of instant scar tissue, stopping the flow of blood and protecting exposed wound area.

6. Catalepsean Node. This brain implant is usually inserted into the back of the skull via a hole drilled into the occipital bone. The pea-sized organ influences the circadian rhythms of sleep and the bodies response to sleep deprivation. Normally a Marine sleeps like any normal man, but if deprived of sleep, the Catalepsean node cuts in. A man implanted with the node is capable of sleeping and remaining awake at the same time by switching off areas of the brain sequentially. This process cannot replace normal sleep entirely, but increases a Marines survivability by allowing perception of the environment whilst resting.

7.  Preomnor. The Preomnor is a large implant which fits into the chest cavity. It is a pre-digestive stomach which allows the Marine to eat a variety of otherwise poisonous or indigestible materials. No actual digestion takes place in the Preomnor. Individual sensory tubes assess potential poisons and neutralize them or where necessary, isolate the Preomnor from the rest of the digestive tract.

8.  Omophagea. This complicated implant becomes part of the brain, but is actually situated within the spinal cord between the cervical and thoracic vertebrae. Four nerve sheaths called neuroglia are implanted between the spine and the Preomnor wall. The Omophagea is designed to absorb genetic material generated in animal tissue as a function of memory, experience or innate ability. A Marine can actually learn by eating. Incidentally, it is the presence of this organ which has created the various flesh and blood drinking rituals for which the Marines are famous, as well as giving the names to Chapters such as the Blood Drinkers, Flesh Tearers etc.

9.  Multi-lung. This is another large implant. The multi-lung, or third lung, is a tubular grey organ. Blood is pumped through the organ via connecting vessels grafted onto the recipients pulmonary system. Atmosphere is taken in by means of a sphincter located in the trachea. In toxic atmospheres, an associated sphincter muscle closes the trachea and restricts normal breathing, thus protecting the lungs. The multi-lung is able to absorb oxygen from poorly oxygenated or poisonous air. Most importantly it is able to do this without suffering damage thanks to its own efficient toxin dispersal, neutralization and regeneration systems.

10.  Occulobe. This small slug-like organ sits at the base of the brain. It provides the hormonal and genetic stimuli which enable a Marines eyes to respond to optic-therapy. The Occulobe does not itself improve a Marin's eyesight, but it allows technicians to make adjustments to the growth patterns of the eye and the light-receptive retinal cells. An adult Marine has far better eyesight than a normal human, and can see in low light conditions almost as well as in daylight.

11. Lyman's Ear. The organ enables a Marine to consciously enhance and even filter certain types of background noise. Not only is hearing improved, but a Marine cannot become dizzy or nauseous as a result of extreme disorientation.

12.  Sus-an Membrane. This flat, circular organ is implanted over the top of the exposed brain. It then grows into the brain tissue until completely merged. The organ is ineffective without subsequent chemical therapy and training. However, a properly tutored Marine may then enter into a state of suspended animation. This may be a conscious action, or may happen automatically in the event of extreme physical trauma. In this condition a Marine may survive for many years, even if bearing otherwise fatal injuries. Only appropriate chemical therapy and auto-suggestion can revive a Marine from this state - a Marine cannot revive himself.

13.  The Melanochrome, or Melanochromic Organ, is hemispherical and black. It monitors radiation levels and types bombarding the skin, and if necessary, sets off chemical reactions to darken the skin to protect it from ultraviolet exposure. It also provides limited protection from other forms of radiation.  Some

14.  Oolitic Kidney. This red-brown and heart shaped organ improves and modifies the Marines circulatory system enabling other implants to function effectively. The Oolitic Kidney also filters blood extremely efficiently and quickly. The secondary heart and Oolitic Kidney are able to act together, performing an emergency detoxification program in which the Marine is rendered unconscious as his blood is circulated at high speed. This enables a Marine to survive poisons and gases which are otherwise too much for even the multi-lung to cope with.

15.  Neuroglottis. Although the Preomnor protects a Marine from digesting anything too deadly, the Neuroglottis enables him to assess a potential food by taste. The organ is implanted into the back of the mouth. By chewing, or simply by tasting, a Marine can detect a wide variety of natural poisons, some chemicals and even the distinctive odours of some creatures. To some degree a Marine is also able to track a target by taste alone.

16.  Mucranoid. This small organ is implanted in the lower intestine where its hormonal secretions are absorbed by the colon. These secretions initiate a modification of the sweat glands. This modification normally makes no difference to the Marine until activated by appropriate chemical therapy. As a result of this treatment the Marine sweats an oily naturally cleansing substance which coats the skin. This protects the Marine against extremes of temperature and even offers a slight degree of protection in vacuum. Mucranoid chemical therapy is standard procedure on long space voyages and when fighting in vacuum or near vacuum.

17.  Betchers Gland. Two of these identical glands are implanted, either into the lower lip, alongside the salivary glands or into the hard palette. Betchers Gland works in a similar way to the poison gland of venomous reptiles by synthesizing and storing deadly poison. Marines are rendered immune to this poison by the glands presence. The gland allows the Marine to spit a blinding contact poison. The poison is also highly acidic and corrosive. A Marine imprisoned behind iron bars could easily chew his way out given an hour or so.

18.  Progenoid. There are two of these glands, one situated in the neck, the other deep within the chest cavity. These glands are important to the survival of the Marines Chapter. Each organ grows within the Marine, absorbing hormonal stimuli and genetic material from the other implants. After five years the neck gland is mature and ready for removal. After ten years the chest gland becomes mature and is also ready for removal. A gland may be removed anytime after it has matured. These glands represent a Chapters only source of gene-seed. When mature, each gland contains a single gene-seed corresponding to each zygote implanted into the recipient Marine. Once removed by surgery, the Progenoid must be carefully prepared, its individual gene-seeds checked for mutation, and stored.  Since the survival of a chapter depends on these glands, they are universally present in all conteporary chapters.

19.  Black Carapace. This is the last and the most distinctive implant. It looks like a film of black plastic when it is growing in the tanks. This is removed from its culture-solution and cut into sheets which are implanted directly beneath the skin of the Marines torso. Within a few hours the tissue expands, hardens on the outside, and sends invasive neural bundles deep inside the Marine. After several months the carapace will have matured and the recipient is then fitted with neural sensors and transfusion points cut into the hardened carapace. These artificial plug-in points mesh with features integral to the powered armour, such as the monitoring, medicinal and maintenance units. Without the benefit of a black carapace a Space Marines armour is relatively useless, so every functional chapter has Black Carapace implants.
