Here's a place to dump concepts for a chapter that relate to a single "thing" that makes the chapter stand out from the crowd. It's the High Concept "summarise a movie in one sentence" thread, where you can stick in ideas for your own chapter.

This isn't a thread for millitary archetypes, or for discussions of the geneseed differences between chapters. It's more a place where you can suggest different ways for Chapters to operate, recruit etc, and other ways in which they stand out from the "Codex Chapter based on a feral world" norm.

Let me give you a few examples from the canon:

• A chapter that runs its own small empire - (The Ultramarines)
• A chapter that allies itself with Rogue Traders (the Marines Errant)
• A chapter that works for the High Lords policing other chapters (The Minotaurs)
• A renegade chapter who remain loyal despite being cast out by the Imperium (Knights of blood...Relictors, possibly. And Soul drinkers too, arguably.)

...and so on.

So here's a few ideas of my own:

1. A chapter that recruits solely from a prison world
2. A chapter that works closely with the Adeptus Munitorum
3. A chapter that works closely with the Officio Assasinorum
4. A chapter that act as, in effect, prison guards for a deadly and immortal being
5. A chapter formed solely to crew an incredibly powerful ancient weapons platform of some type
6. A chapter that acts as agents for the Adeptus Custodes
7. A chapter that worships a controversial aspect of the Imperial faith
8. A chapter that suddenly appears after three thousand years lost in the warp, not knowing the time has elapsed
9. A chapter that operates totally in secret: an Imperial version of the Alpha Legion
10. A chapter that works closely with the Ordos Xenos
11. A chapter that polices the Black Ships
12. A castellan chapter: a chapter that guards a major point of entry into the Solar System
13. A chapter that was created specifically to counter a specific threat which is now extinct
14. A chapter that is ravaged by internal dissent over a doctrinal point
15. A chapter that extorts resources from surrounding Imperial worlds
16. A chapter that has become inefficient and flawed
17. A chapter who hates its founding Legion and plots to destroy it
18. A chapter which conceals its own secret shame: cowardice, geneseed problems etc
19. A chapter which specialises in the use of a weapon not employed by any other chapter
20. A chapter which plays politics
21. A chapter which operates its own spy service
22. A chapter which specialises in some aspect of the Codex to the detriment of all else
23. A chapter which has a grudge against another chapter
24. A chapter which has a grudge against another Imperial Institution
25. A chapter that had suddenly executed all of its Librarians
26. A chapter created to occupy a certain ancient space station or artefact (like a Blackstone Fortress)
27. A chapter constantly under siege, slowly losing ground, refusing to give up.
28. A chapter suffering a moral or religious crisis
29. A chapter which is attempting to comply with the terms of an ancient secret pact
30. A chapter which is attempting to ensure that an ancient prophecy doesn't come to pass
31. A chapter which is dying, but which wants one last battle
32. A chapter which specialises in exterminatus and ultimate weapons of that ilk
33. A chapter which is so extremely pro-codex that it deliberately starts wars with others who are less hardline
34. A chapter that specialises in major fleet actions/hunting renegade Imperial Fleet officers and policing space lanes
35. A chapter that specialises in urban combat
36. A chapter that specialises in aquatic combat
37. A chapter that is allied to a particular xenos race or faction
38. A chapter that is slowly going totally insane
39. A chapter that promotes jealousy among other chapters
40. An arrogant chapter that is widely hated
41. A chapter that is undergoing a penitent crusade
42. A defeated and shattered chapter
43. A chapter which has been politically outmanouvered, and which now carries out tasks it hates for a master it despises
44. A chapter with limited resources
45. A chapter with more resources than it can handle
46. A chapter with too few marines to continue
47. A chapter that has over 1,000 marines
48. A chapter that has committed a terrible crime
49. A successor chapter to a successor chapter which itself was not of the First Founding: a chapter which fears it has dilute geneseed
50. A chapter which does not know it's gene-ancestry

Well that's 50 to be getting on with...anyone want to add any more? If we can get 50 more, we can do a D100 table!

66. A chapter that recruits from the near dead. Lots of cyberware to be found.

You could combine this with a chart I did earlier for random generation of the chapter's geneseed:-

D1000 (roll a D10 three times)

Roll Result
001-600 Ultra Helix (Ultramarines)
601-750 Pugnus Helix (Imperial Fists)
751-850 Umbra Helix (Dark Angels)
851-930 Fulmen Helix (White Scars)
931-960 The Helix Sanguine (Blood Angels)
961-970 Ferrum Helix (Iron Hands)
971-973 Canis Helix (Space Wolves)
974-984 Nex Helix (Raven Guard)
985-000 Other sources (Chimaeric, unknown, Traitor etc)

So to follow this through as an example of how to generate a chapter using this system, I roll twice on the first table and once on this one.

I'll do it now: 89, 16 and 638.

So this is an Imperial Fists successor chapter from a world devastated by an unknown race or monster, a chapter that has also become inefficient and flawed.

Stannis Ravensight said:

Oddly enough, this may actually be an inherent quality of Space Marines anyway - the Horus Heresy novel Deliverance Lost suggests strongly that individual Primarchs had genetics derived from particular Terran animals as part of their fundamental nature (as well as countless other variations - each was designed differently from a common baseline), which in turn influences the genetics of their Astartes progeny. In short, Leman Russ was already part wolf, and thus the Space Wolves' canine traits are actually the result of canine genetics spliced into their geneseed by the Emperor.

Some more ideas, I guess we could use a D666 list if we get enough (or would an D888 list be more fitting)

101. A chapter that have somehow lost most of its Power armour, making what little they have left something that is only for the use of veterans and heroes, normal marines have to do with scout armour .

102. A chapter style itself after an, for Space Marines, unusual totem animal (spider, baboon, hippopotamus, yak, crocodile, etc.) and follow that animals "teachings", makes modification to their war gear to resemble totem and maybe use members of that species in their warfare.

103. A chapter usually only operate on War Worlds where the empire have been fighting for decades, decapitating the enemies leaders, destroying their main fortifications and/or weapons and then leaving.

104. A chapter where one in ten of its members begin to mutate into a degenerated combat form (maybe physically resembling crypt ghouls, strigoi or wolfen) before they reach Veteran status.
