List of Chimeric Chapters

*This article, List of Chimeric Chapters, is a community project. While you are free to edit, please do not edit or delete anything written by another user without their permission. This page was last edited on 8/12/2023 by Algrim Whitefang*.

This article is comprised of a complete list of all the fanon Space Marine Chapters created by our contributors here on the WH40K Homebrew Wiki that possess so-called 'chimeric' gene-seed - indicating that somehow the genetic material of these Chapter were either procured from a prohibited source, mixed with a heretical genetic pool, adulterated or somehow tampered with during its creation. Along with a brief synopsis of each Chapter, this list also serves as a visual reference and archive. Included in this list are Expanded Universe Chapters as well as those Space Marine Chapters that have been declared *Excommunicate Traitoris* by the High Lords of Terra, regardless if they serve the Dark Gods or not. This list does not include Space Marine Chapters that fall into the humour category. This is an ongoing project, and as such, additional Chapters will be added or removed accordingly. For those Chapters that are missing from the list, please feel free to edit this article and add it, or if the Chapter article has been deleted, feel free to remove it.

 Angels Palatine |  | The Angels Palatine are a rather active, and somewhat well-known loyalist chapter of the Adeptus Astartes created during the ill-fated 21st Founding, the so-called 'Cursed' Founding, created from the proud lineage of the Blood Angels. This Chapter is located in a grouping of systems known as the Bright Stars, which are comprised of lush and mineral rich worlds within of the Segmentum Obscurus. Their whole reason for existence is to act as the defense force and arbiters of the Bright Stars, their main objective to defend the Stars from invasion through a semi-stable warp rift in the area known as the '*Malum*', or '*The Evil*', as well as reinforcements, should the Cadian System, and it's Cadian Gate, required aid. Most of their active duty is spent destroying minor Chaos incursions into their system, as the both the Malum and Eye of Terror (a giant warp-rift in realspace that leads to the hellish Realm of Chaos) resides in close proximity.

 Blood of Vulkan |  | The Blood of Vulkan is a loyalist non-*Codex* compliant Space Marine Chapter of the Adeptus Astartes created during an Unknown Founding and of dubious origins. A bellicose and ferocious Chapter, these Astartes have developed unique abilities that enables them to be nigh unstoppable in close melee combat. These abilities include pyrokinetic breath that allows them to breathe fire and the ability to call upon the inherent rage of their Primarch, making them unstoppable berserkers.

 Graven Skulls |  | The Graven Skulls are recognized as a Loyalist Space Marine Chapter of unknown Founding and origin. These frightful and cryptic marines are a more horrifying, nightmarish force of power armour-clad spectres, rather than the mythic figures that the Imperium idolises as the Emperor's Angels of Death. Mystery and suspicion attach themselves to these dour and macabre warriors regardless of their true loyalties or intentions, and while they nominally serve on behalf of the Imperium, they prefer to operate independently, shunning all brotherhood of their fellow Adeptus Astartes Chapters. The reason for such insular tendencies is unknown, though some believe they are attempting to atone for some great sin committed in their past, and therefore, hide their shame until they can redeem themselves in the eyes of the Emperor.

 Star Crusaders |  | The Star Crusaders is a relatively young Loyalist Space Marine Chapter founded in M39 during the 24th Founding as a fleet-based Chapter to conduct space warfare, low/zero-g combat as well as a rapid response against enemy fleets who were able to penetrate deep into the Imperium. The Chapter's most notable battles were against the Tyranid Hive Fleet Leviathan which attacked the galaxy in two directions from below. Such an attack was an example of why the Chapter had been formed and currently is engaged with the remaining part of this hive fleet.

 Umbral Wraiths |  | Created during the mysterious 13th 'Dark' Founding, there is very little extant evidence about this mysterious and highly aloof Chapter. Initially, the Umbral Wraiths were created as a powerful and versatile xenos hunting Astartes Chapter. Their purpose was to lend to aid various wings of the Imperium, and to a lesser extent, be the sword the Imperium so desperately needed. While Deathwatch and the Ordo Xenos were to patrol the borders of Imperial space from xenos incursion, the Umbral Wraiths were to dive into their territory and act as both scout and vanguard. The Chapter was to be made of Dark Angels and Raven Guard gene-seed. However, the Raven Guard's genetic material was too unstable and too precious for such an experiment, especially with the Death Spectres produced within the same Founding. As a result, the Umbral Wraiths were given; --- ##REDACTED – ORDER OF THE INQUISITION## ---
