- Chapter was considered lost after a warp accident in 36m, multiple transport barges exiting the warp became superheated and ignited mid jump. Only wreckage of some craft was discovered close to the Raven Guard’s homeworld of Deliverance centuries later. The only surviving companies were the 8th and 10th which, these were disbanded and assimilated into the ranks of the Ultramarines. Leviathan 2 was lost to this accident, 3 and 4 were docked with their orbital facility with the intention of repurposing them at a time however this location has since been lost.

So I've posted a sample list for judgement awhile back which I'm currently painting, reading some of the novels atm and I thought I'd try and jot down in dot points how my marines from 5th edition somehow turn into my new marine army. Below is what I got, any ideas or thoughts or anything that seems contradictory let me know, I'd like opinions For gamer's I've also picked out a few high level rules that the Chapter must follow to keep with the fluff also.

Revolution Marines:
- Established during the 35m,

chapter was designated as a standing force to operate in outlying imperial outposts. Specifically aiding in resource collecting operations to supply loyalist forces forge worlds with much needed fuels.

Due to their need to constantly travel between systems, the chapter developed oversized battle barges to act as flagships, these were named Class 0 Leviathan’s. A total of 4 were created, 1 was destroyed only moments into its first voyage, its superstructure collapsing under its own weight. All following productions incorporated extensive supporting exoskeletons to avoid this issue.

- The chapter was involved in many conflicts, despatching battle companies to aid loyalists in adjacent systems to where they resource collecting activities were occurring. 1st company veterans were rarely despatched in the interests of protecting the mining operations first and foremost.

Re-emergence:
- In 41m, Raven Guard companies in close proximity to Deliverance were called to aid their homeworld after a large warp storm erupted in the same system, fearing it may prelude a incursion of Chaos marines.
- Wreckage matching the description the Vorpal Swords gave is ejected from the warp storm before it closes, Raven guard boarding forces investigate the wreckage and identify it as the Leviathan 2 from its remaining intact interior.
- To their horror, the boarding party find a total of 312 marines in cryo stasis, snap frozen inside their suits

by the ship’s AI

which in response to the igniting transport barges in the warp storm in which they were lost deemed an appropriate response to save the marines lives. By sealing the the innermost chambers and flooding the rooms with liquid hydrogen (usually used as fuel) it had successfully frozen the marines before they were destroyed.

- Apothecaries are called in from multiple chapters to attempt to resurrect the marines, of the original 312, 83 survived and were deemed suitable for combat.

Among the survivors were two members of their 1st companies command squad, Tobias Green,

an experienced assault specialist and Dominic Fox

Several of Raven Guard’s shadow captains take it upon themselves to outfit and re-train the revived marines.

A new name is chosen to show that these marines that came out of the storm are not the same any more.

The Iron Rangers:
- A by product of their ordeal, the Iron Rangers have over sensitive eyesight as a defect in their geneseed.

- Their affinity with the warp has made them respect and admire naturally occurring storms, the shade they provide assists with their sight and concealing their infantries movements.

- The Leviathan 2’s AI

which saved them is retained by Iron Rangers, Inquisitors request to take the AI for study is denied by Tobias, this causes the some outrage by the Inquisition and threatens excommunication of the Rangers however this remains unresolved tension between the two groups to date.

- Retrofitting a light supply cruiser named the Hades, the Iron Rangers are today a fleet based chapter in search of their original home world and lost Forge station. Inspired by the Raven Guard’s actions, the Rangers following in their teachings by responding to lost worlds calls for help against those that oppose the imperium. All the while combing the galaxy for their true home.

Okay, here is some of my thoughts:

There is no gravity in space... How does a spaceship collapse under its own weight? That is only possible I think if you'd land it on a planet or something (which 40k spaceships never do) or if it is so large it has a gravity field of its own (in which case it would be way too large for a Space Marine chapter too have).
