Editing Gene-seed (section)

==== Raven Guard (XIX Legion) ====
{{Main|Raven Guard}}
* Malfunctioning Melanchromic Organ (their skin is always pale and their eyes are always dark. Anti-Salamanders, basically.)
* Missing Mucranoid (no super-sweat).
* Missing Betcher's Gland (no acid spit).
* Occasional bouts of suicidal rage (Luckily for them this is not permanent unlike a certain other chapter.)
While their primary gene-seed is decently stable, when under extreme stress a percentage Raven Guard warriors will lapse into bouts of suicidal rage known as Ash Blindness or Sable Brand. This is rarely permanent, but occurred with enough frequency that [[Corax]] would organize these warriors into the [[Moritat]]. Their missing and malfunctioning geneseed organs is a result of [[Corax]], out of desperation following the [[Drop Site Massacre]], delving into use of forbidden lore and archeo-tech from days long past to accelerate gene-seed maturation, and try to boost his Legion's numbers after their losses during the [[Horus Heresy]]. He was successful, until the [[Alpha Legion]] decided to make the whole project go FUBAR. The subsequent 'Marines', if they can be called that, were numerous, but were barely controllable monsters and/or would simply die off as a result of the extreme imbalances in their dispositions. Presumably, a few of them would even have functioning Progenoids, let alone usable gene-seed. Due to the law of averages though, at least a FEW would have had to been stable enough, and is being worked on secretly by the Raven Guard Apothecaries and associated [[Adeptus Mechanicus|Mechanicus]] Biologicans.

Otherwise, despite being pretty fucked up by the [[Drop Site Massacre]], they've mostly recovered (thanks in no small part to having the ''only'' loyalist Primarch to get away from the Massacre in one piece) and do still contribute to successors [[Death Spectres|here]] and [[Raptors (Chapter)|there]].

===== Raptors =====
* Same as the Raven Guard, except they have functional Bletchers Glands (making them more like [[Night Lords|another black-eyed / pale skinned gene-line]]).

===== Death Spectres =====
* Similar Melanchromic Organ as Raven Guard, though a specific shade of albino and their eyes universally glowing red (basically albino Salamanders).
** also gives them a 100% certain chance of alopecia. (They are genetically bald From the day they were born till the day they die)
