Wasn't quite sure where to put this, but as I couldn't find a single example of a new chapter in any of the other subforums I'll assume this is it.

Asking for a little help and ideas as I walk through making out a chapter that has had a lot of local in game action lately and features heavily in my role playing and table top games. I figured with the rites of battle new chapter creation they could use some fleshing out.

I'll jump straight to task and include a core dump of what I have so far just running the charts later. I'd love anyone with spare time trying to guess what I'm working at, just so I can see how close I'm getting to my core idea set. Beyond that I see things in the other listings I can't find in the books I have, primarch's curse, specialty relics, etc etc. Just how much stuff could I add in here. Be great fun hashing the details out.

Or maybe people have done this too often and it'll fall on deaf ears, whichever.

That core dump.

Why so many colors for the livery? Can you be more specific as to what they are used for?

I think a little assistance from Capt. Mathias would be helpful.

Though he uses an alternate scheme reserved for Captains it should show up. My other images of the chapter units are a touch blurry.

I'm not sure you can quite get the idea from this one, but it may be helpful. I've currently and utterly forgotten the names of certain pieces of armor or I'd just list off what is what color.

The rules presented in Rites of Battle are intended for both GMs and players to create new chapters. As such they leave quite a bit of things unexplored to try and maintain balance. If you want to make a new chapter just for your group, you can essentially use your best judgement on everything. If anything gets out of hand later, you have GM power over every PC and can nerf your previous mistakes on the fly. If you want to publish your own chapter for other GMs to use, make sure it's something you'd be comfortable having it in your run first, and that it's complete. This means psychic powers, solo/squad mode, history, primarch's curse, chapter trappings, chapter advances… etc. Anything beyond those adds great depth to the chapter and can be a lot of fun, but don't start worrying about those until the core concepts are there. If your chapter is a successor that's reasonably close to the original chapter in behavior and organization you have far less work to do. In that case all you need to do is add one or two rules that tweak their original concept without breaking it or making it entirely better than the original chapter, explain their history, and maybe (if you want to emulate Rites of Battle) throw an adventure seed in there. At that point the chapter can be released for other GMs to try, though they will likely be less excited about just one new successor. Still, don't let that discourage you if it makes sense for your chapter. If the chapter is too similar to their origin chapter DO NOT write entirely new rules for them. They will feel forced and uninteresting.

In the end the point is to have fun and add more options to the game either for yourself or others, so go have fun!

Well that's nice Rob and I appreciate it but it's only tangentally helpful.

You mentioned primarch's curse, chapter trappings, chapter advances, I wasn't seeing them fleshed out in rites of battle, or maybe I missed them. Would you tell me where to look for those extras? They certainly aren't in the charts. Since this is a third founding chapter, with… what… 8000 years of history behind them, they've certainly diverged from their parents in the intervening space of time.

One thing I need to check, I read once that the Doom Eagles are a second or third founding chapter of the Ultramarines, but can't confirm it anywhere. Anyone know where to look?

Besides that this chapter started out first in Battlefleet Gothic and it's special rules are based in mass fleet combat, I'm unsure how to even translate that to FFG but I'm up for trying. It just goes with the thread of me needing help to get this done and working things out a step at a time.

Hate to double post, but I just got this done, and it was hell to write. The first couple of paragraphs must be the worst thing I've written in the last decade, but I think I started catching my stride at the end. We'll see, at least my nickname SirRunOn will make more sense.

Causation and Notes on the Marines of Wrath, M32-M36, begin:

First founded in the mid 32nd millennia the Celestial Wrath chapter only found its current form in the wake of the age of apostasy.

As of 897.M32 strategic after action reports found Space Marine fleets, while quite capable of creating beach heads on even well defended planets, a prerequisite of their construction, generally required support from other fleet elements to approach and stay in contact with space borne targets such as hulks, craftworlds, and larger chaos vessels. As the adeptus astartes was considered outside general chains of command in this they inherited a problem with getting needed space bourne support for extended engagements beyond exceptional circumstances. This was often compounded by the need for a chapter to be able to fight on the surface of a world and keep it's skies clear at the same time. During such invasions the requisite number of battle brothers for the marines best space borne offensive punch, namely the boarding attack, were almost always arrayed elsewhere, and though battle barges and strike cruisers were well outfitted for short forays into contested areas without sufficient battle brothers to embark on these boarding actions they were considered to be slightly under gunned in naval battles.

A board of inquiry was convened to react to this report, and while they found that the times when space marine ships were caught alone against space borne foes were infrequent, such occurrences were happening often enough to warrant the creation of at least one chapter with the specific goal of success in naval engagement. In accordance to this another special board was convened, this time mostly of naval personnel under the watchful eye of the astartes and fledgeling inquisition, to design a single purpose built chapter.

What was worked out, and became fact in 918.M32, was not a single chapter, but an unusual pair of brother chapters. These brother chapters, the Ira Caelestis and the Celestial Wrath, one successor to the Ultramarines, the other the Doom Eagles, shared similar ethos, responsibility, livery and most unusually the same fleet. Each chapter was organized by codex norms, though as per their Doom Eagle heritage one possessed an unusual number of available jump packs and could as needed field a large number of assault marines.

Sparing no expense the chapters were outfitted with the newest prototype Battle Barges and Strike Cruisers, fresh off the shipyards of mars and some of the earliest of their kind. Stronger than similar classes of ship these more heavily armored vessels were eventually dispersed to the Inquisition and in a lesser form to all space marine fleets so that most current Battle Barges and Strike Cruisers rely on their boxy, well armored and armed, utilitarian designs.
Operating in tandem, one striking in space while the other conquered the ground, the two chapters saw success early and often, and though detractors pointed out this was likely due to the fact they could throw twice as many astartes at a problem as usual, the prevailing wisdom, in a rare moment of clarity, decided if it worked, why not use it? So valued was this spaceborne attack force that in every successive founding one successor chapter sported their genetic material.

As the millennia passed and the chapters drifted towards each other and away from their respective origins a number of personal quirks began to show up. As the two chapters intermingled it became harder and harder to tell them apart, only a slight difference in the order of pauldron colors separating them. During the 35th millennia an internal decree of rather dubious merit had each chapter's first company adopt the livery of their brother chapter, confusing the matter to almost insurmountable proportions and spurring a number of jokes similar to the old and oft recounted "mork, or maybe gork" humorisms. To further the confusion the Ira Caelestis… or maybe the Celestial Wrath, whichever of them was in space, since no one knew anymore, began to grow into the available space their large craft allowed them, slowly adding five extra companies of marines over the space of two thousand years.

As expected, this all came to a head at the end of the Age of Apostasy.
