I'm currently nearly 15,000 words into a story about a scenario in which Abaddon makes it to Terra and while the Blood Angels and many other chapters rush to its defence but no more aid or reinforcements are possible (due to a combination of the Imperium being broken by other conflicts and the Chaos Gods messing with warp travel).
The story is told from the perspective of Barachiel, a powerful telepathic librarian of the Blood Angels. I've taken a slightly 300-esque approach in that my focus is more on describing individual encounters/skirmishes and the big events as opposed to depicting the siege as one titanic battle, as the latter makes the heroism of individual space marines rather inconsequential (one of the things I hate about 30/40k and especially Apocalypse battles is scooping handfuls of marines off the table. Barachiel's telepathy continually spawns plot holes for me to patch, but I think it's worth it as it means I can better explore other characters' emotions while still maintaining a first person perspective.
I was originally looking to combine it with images of my Horus Heresy and 40k Blood Angels (and may one day do so), but the story is so far ahead of my painting backlog (and new painting projects keep springing up), that I'd rather publish it online first.
Because my writing style is pretty sparse (I'm a journalist by trade), it won't take me long to wrap it up. However, I'm curious to know if there's anything you guys would particularly like to see? I'm already featuring the Black Rage, the Sons of Sanguinius' hatred of the Black Legion and the effect the Talon of Horus has on them. Because this story is essentially about the end of the current 40K setting, anyone can die (with one notable exception....).
Also, given that I made the rooky error of suggesting that vegetarianism is a good survival strategy on Baal sometime back, is there anything is a big no-no for you? I should add that I'm a massive fan of ADB's Night Lords and there are some homages to them in the piece. I've also modified it so that Guilliman is leading the defenders (given his recent return thanks to the Gathering Storm series).
