I was at the garage table on Thursday with my phone propped against a pot of Abaddon Black, scrolling Aethon Shaan’s datasheet because one of the regulars had finally built his. He’s the only Raven Guard player in our group, and he’d asked me to check a rule for him, which is a bit like asking the man with the Imperial Fists to proofread your camouflage. Halfway down the card there’s a box called Chapter Master of the Raven Guard. If your army includes Shaan and Kayvaan Shrike, Shrike loses Lone Operative and swaps his Chapter Master keyword for Captain.
I read it out loud. He said “yeah, he quit,” like everybody knew.
I didn’t know. I’d seen the Shaan model go up last September, thought “nice hood,” and moved on, because I was busy not painting my Cadians. So I went and read White Dwarf #517’s section on the Raven Guard, and the Kauyon book, and a fair amount of Lexicanum at midnight. It turns out Shrike, the most famous Raven Guard since Corax, looked at the Chapter Master who’d died before him, recognised the same flaw in his own personality, and stood down. WD #517 says it spoke to Shrike’s strength of character that he’d step aside willingly, which is about as close as White Dwarf gets to editorialising.
Severax went after Shadowsun’s head
You need the man before Shrike for any of this to land. Corvin Severax was Chapter Master during the Damocles Gulf campaigns in the 7th edition Kauyon book, and he was, by that book’s account, very good. His search-and-destroy patterns on Prefectia were working. Then Shrike’s veterans voxed in a sighting of Commander Shadowsun standing over a field of dead Guardsmen, and Severax went to get her head personally.
The figure he went for was bait. Kauyon describes her commissioning ten XV22 suits painted up in her own honour markings, flown by volunteers, specifically so Imperial commanders would chase the wrong one. A decoy pilot called Shue’la drew Severax in, and Shadowsun killed him herself from inside a Ghostkeel. Most of the 3rd Company died in the same engagement, and the 3rd was Shrike’s own company.
Shrike’s response that night is the reason he got the job. He and his Command Squad went back onto the battlefield after dark and cut the progenoid glands out of the fallen, at real risk, and got most of the 3rd Company’s gene-seed home. If you know anything about Raven Guard gene-seed, you know why that mattered. Their stock degraded after the Heresy, and the Angels of Death codex supplement is blunt about it: they can’t replace losses quickly, so every battle-brother’s life is worth more to them than to almost any other Chapter. The Shadow Captains voted unanimously, and Shrike became Master of Shadows.
There’s also a speech in the book where he tells the Chapter it’s going to work with every ally it can find from now on, and a good chunk of the room stays quiet, which Kauyon mentions once and never comes back to.
Shrike watched his captains without telling them
Fast forward to the Indomitus Crusade. White Dwarf #517 frames the Raven Guard around something it calls the Trifold Path, Corax’s three tenets of Ambush, Stealth and Vigilance. Most commanders lean toward one of them. Shrike had worked out that both he and Severax leaned hard into Ambush, and that the thing that killed Severax on Prefectia (pride, battle-lust, the urge to take the big head yourself) was sitting in his own two hearts too. The magazine says it plainly: he believed Severax’s death was an avoidable waste, and he knew he carried the same vanity.
So he went looking for a replacement, and he did it the most Raven Guard way imaginable. He scattered his best commanders across the Imperium on separate warfleets, didn’t tell them where the others were, didn’t tell them what he was doing, and watched. None of them were told it was a job interview, and WD #517 doesn’t say how many candidates there were.
I keep going back and forth on how I feel about that. It’s your Chapter Master running an undercover assessment on his own officers in the middle of the worst crisis in ten thousand years, which is roughly the energy of a manager who reads your Slack messages “just to get a feel for the team.”
Shrike himself came up the hard way, for what it’s worth. He was a runner for a Kiavahr gang called the Tarkal Guild, evaded rival gangers for over a week as a teenager, got caught, got tortured, escaped and killed a lot of them. The Chaplains noticed. He chose the name Shrike after the hunting birds in Kiavahr’s mountains that attack prey bigger than them. You can draw a pretty direct line from that teenager to the Chapter Master who saw Shadowsun and went for her, even if Shrike himself didn’t make the call that day.
Aethon Shaan was in a Graham McNeill novel first
This bit genuinely surprised me. Shaan comes from The Chapter’s Due, the sixth of Graham McNeill’s Ultramarines novels, which came out in 2010. That’s sixteen years ago, which is about my entire time in the hobby plus the year I spent insisting my Cadians were “just a side project.”
I read that book. I’m fairly sure I read it on a train. And I have no memory of a Raven Guard captain in it at all, which is embarrassing given that he apparently walks into Marneus Calgar’s chambers in the Fortress of Hera so quietly that Sergeant Telion doesn’t spot him. Telion, of all people, a man with a sniper rifle and a datasheet built around noticing things.
According to Lexicanum’s summary, Shaan’s job in the novel was to collect Ardaric Vaanes, a renegade Raven Guard running with Honsou’s Iron Warriors. His squad infiltrates Axum, blows up the Iron Warriors’ command vehicle on Calth, and at one point he casually beheads a Khorne Berserker who’s clinging to the outside of an evacuating Thunderhawk. Then Vaanes dies fighting on the right side at the end, and Shaan doesn’t know what to tell the Ravenspire. Uriel tells him to tell the truth. Shaan has Vaanes’s gene-seed extracted to take home.
Which is a nice quiet character beat for a supporting cast member in 2010, and it sat there for fifteen years until the design studio needed a new Raven Guard Chapter Master. WD #517 says that over the centuries he’s led the 10th, 8th, 4th and 1st Companies. As 1st Company Captain he held the title Lord of Deliverance, ran the homeworld’s defence and, more interestingly, the Chapter’s information networks. His specialism is a Rite of Shadow called Spraakfys, which deals with truth and falsehood, the idea being that Corax taught that shadow holds both.
The militia on Aescia II never got to tell anyone
Shaan’s audition happened in the Segmentum Solar. He was handed a small mixed force pulled from several companies, and WD #517 lists three results. Infiltrators and Incursors sabotaged the atmospheric scrubbers on Gelvia and poisoned a Genestealer Cult. His frigates crippled an Iron Warriors cruiser in the Strigneth System and used it as bait to lure in more heretics. Then there’s Aescia II.
Aescia II is the one Shrike cared about, because it’s where Shaan showed restraint. He was first on the scene of an enormous Ork invasion, hopelessly outnumbered, so he kept his ships in the outer system and watched. He sent surgical strikes against Ork ships and assassination teams after ambitious bosses. Cells of veterans went down to the surface, found isolated militia companies, trained them, and pointed them at the Orks, which made the Orks divert more and more effort into wiping those militias out. When the Astra Militarum finally arrived, the planet was basically back in Imperial hands. Its leaders believed they’d done it alone.
Right. I read that paragraph three times. The line in the magazine is that the militia the Raven Guard contacted “never survived to spread the word.”
Is that the Orks killing them, or is that the Raven Guard making sure? I honestly don’t know, and I don’t think White Dwarf wants me to. The charitable reading is that Shaan used the militias as a distraction and the Orks did what Orks do. The less charitable reading is the Spraakfys bit from earlier, controlling which truths get out, applied to people who’d seen a Space Marine and might mention it. Shrike watched all of that and decided it was what he wanted. I’d originally written this section as “Shaan won with minimal losses,” because that’s how Lexicanum summarises his three victories, and I’m still not sure whether to put that back, since it’s accurate as far as the Raven Guard headcount goes.
The Blackwing Mantle and the Claws of Severax
There was no ceremony. Shaan got summoned back to the Ravenspire, a handful of officers and the Reclusiarch turned up, and he was invested as Master of Shadows while Shrike carried on a shadow campaign in the Bastior Sub-sector. Shaan took the Blackwing Mantle jump pack and the Claws of Severax, both recovered from Prefectia by Shrike along with Severax’s body. Then he left Deliverance.
So Shaan goes to war with Severax’s own claws, handed over by the man who quit for fear of ending up like Severax. I suspect the writer did that on purpose, though WD #517 never says so.
The model’s lovely, by the way. Three heads (helmet, rebreather, hood), a big rock perch, and a set of little mechanical birds trailing scrolls. Those are the avian servo-automata from WD #517, anything from mostly vat-grown to entirely mechanical, that roost in the Ravenspire’s eaves and follow Shaan around feeding him data. To the Chapter they’re also a comfort, a reminder that Corax is supposedly still watching. My local store had the kit on the shelf next to a Ravenstrike Battleforce for most of the summer, and I picked it up twice and put it back twice, because I’ve got nineteen unbuilt Kasrkin in a drawer and no business buying a Chapter Master for an army I don’t own.
On the table it’s Shrike who has to adjust
The 11th edition Codex: Space Marines gives the Raven Guard a detachment called Shadowmark Talon, and it’s very Shaan-coded. Every Adeptus Astartes unit in the army has Stealth, Phobos and Scout units get -3” detection range, and Shaan makes the Into Darkness stratagem a point cheaper once per battle round. There’s a Suppressed Weapons stratagem that lets an infantry unit shoot and still stay hidden. Combine that with Wednesday’s balance update putting Phobos armour on an 8” move and Raven Guard players have had a very good September. (I’ve got a whole post on why I never warmed to Phobos, and 8” is starting to change my mind.)
The demotion box on Shaan’s card is from the free datasheet GW put out when his model launched in September 2025, and the codex isn’t in my hands yet, so I can’t tell you whether it survives word for word.
If you want more Raven Guard family history, the Ashen Claws are the XIX Legion’s exiled 18th Chapter and the Raptors are the successors who spent thirty years cut off from everyone. Both inherited the same gene-seed problem that made Shrike crawl around Prefectia in the dark collecting progenoids. The Iron Hands came out of Isstvan V in the same state and turned the grief into a religion.
Anyway, he ran both of them in the same list on Thursday: Shaan with a unit of Vanguard Veterans, Shrike demoted to Captain and attached to Assault Intercessors with jump packs, no Lone Operative. Shrike died turn two to a lascannon. Shaan didn’t come down from Strategic Reserves until turn four.
