The skin-cloak and the Clone Lord
Fabius Bile wears a cloak made from human skins. The skins are from Istvaan V, where the III Legion burned the Iron Hands and the Salamanders and the Raven Guard together in the Dropsite Massacre, and Bile collected what he wanted from the survivors. He has had the cloak ever since. He had it on Arden IX, where he forced the people he’d skinned to carry the train behind him like a wedding dress. He probably still has it in a closet somewhere in his laboratory.
Bile has been around for a very long time. Chief Apothecary of the Emperor’s Children during the Great Crusade, Renegade from his own Legion by the end of the Horus Heresy, ten thousand years of research in the Eye of Terror since then. The Fandom wiki has nine separate subheadings under “History” just to cover the major incidents. He’s killed Blood Angels Successors on Baal, taught torture to Drukhari haemonculi at Commorragh, cloned Horus’s corpse, cloned Ferrus Manus, cloned Fulgrim and then sold the clone to Trazyn the Infinite when he got nervous about how it was turning out. He has more page space in current canon than most Primarchs.
He is not, however, in the new Emperor’s Children army.
Absent from his own Legion’s codex
The Champions of Slaanesh box and the accompanying Emperor’s Children codex gave the III Legion its first proper army book in years. Fulgrim got a new model. Lucius got updated rules. Noise Marines, Lord Kakophonist, Scarabine, the whole Slaanesh-drenched roster. If you were picking favourites in Chaos you’d probably expect the man who ran the Legion’s Apothecarion before the fall to be in there somewhere. He isn’t.
Fabius Bile’s datasheet still lives in the Chaos Space Marines index, where it has lived for the whole of 9th and 10th edition. You can ally him across into Emperor’s Children if the rules that week allow it. His datasheet still belongs to the generic CSM book. He’s not printed in the III Legion codex itself, and he’s not in the roster GW is selling as the definitive Slaanesh Legion army. The detachment named after him, Creations of Bile, also sits in the CSM book.
This is the bit the 40KLore subreddit has been circling around for weeks. Where is Fabius in all of this? Why is the character with the deepest, weirdest connection to the Emperor’s Children absent from their codex?
Why the Legion moved on without him
He’s been a renegade from his Legion for a very long time, and Fulgrim has been glad to be rid of him. Bile left Terra before Horus’s defeat with a handful of his best acolytes, which incensed Fulgrim enough to put a bounty on his former Apothecary’s head. He has spent the millennia since selling his services to Death Guard, Black Legion, Iron Warriors, Night Lords, the Thirteen Scars, occasionally the Emperor’s Children themselves, and refusing to commit to any of them. Canticle City on the Daemon World of Harmony was his base for a while after the Heresy. His permanent home is now a Crone World called Urum, somewhere in the Eye of Terror, where he runs an apothecary network called the Consortium that operates across Legion lines.
Bile does not worship the Dark Gods. He considers them natural phenomena: vast, unpleasant, useful to study. He still holds to a version of the old Imperial Truth, in his own twisted way, and treats his scientific work as the only thing that matters. Every author who has written him keeps this consistent. The Legion that rebranded itself around Slaanesh worship has not had an easy time explaining where Bile fits into that structure.
Then there’s Fulgrim. Bile has cloned his Primarch multiple times. A version of that clone remembered the entire Horus Heresy, repented for it, and was about to try and atone before Bile sold him to Trazyn the Infinite because the clone was turning out too much like the original. Fulgrim knows about this, and has known for a long time.
What he’s actually doing
Current lore keeps Bile in Era Indomitus, working out of Urum, running the Consortium, selling genetic expertise to whichever warband has the most interesting prisoners that week. In the War of the Spider he stole the Ark Cornucontagious from Typhus, spent the subsequent crusade turning the Shriven warband into a private army of Terata, and in the final battle on Dessah he walked away with captured Adeptus Custodes and Sisters of Silence in his hold while Death Guard and the Shriven killed each other. He collects Primaris wherever he can find them, hoping to eventually harvest Guilliman’s gene-sample.
His real project is still the New Men. The enhanced baseline humans he’s been seeding across the galaxy for several millennia, his attempt to do what the Emperor did and do it better. Most of them fail. The successful ones look like people until something in their heads gives way, and then they start killing. The Inquisition cleanses worlds wholesale when they find populations that are too far gone.
The thing keeping him alive is the Chirurgeon. The multi-armed surgical rig bolted to his spine. It pumps him full of serums, swaps his failing organs on the fly, and performs surgery on him while he’s walking. The Chirurgeon is described as having a “darkling sentience” of its own, and the honest reading of the current Bile is that the rig is doing most of the heavy lifting. Bile is a skull and a set of opinions and a brain full of four thousand years of accumulated scientific spite, being wheeled around by a sentient spider-armour that he built himself. I find that more interesting than the cackling-mad-scientist version of him, though both are in the books.
A conversation with Kiran about Clonelord
Kiran got me on the Josh Reynolds trilogy in 2019, in a GW on a Saturday, which is the wrong kind of environment for this conversation but the one we had. He was halfway through Clonelord, the second book, and was using it to argue that Fabius was the most interesting Chaos character in the setting. I was running a Thousand Sons list I’d spent too much money on and had opinions about Tzeentch I was probably too loud about.
Kiran’s argument was that every other major Chaos character has a plan that depends on the Warp staying open or the Emperor dying or some specific god ascending. Fabius does not. Fabius’s endgame is a new species. If the Warp sealed tomorrow and all the Chaos gods were banished, he would keep working. If Slaanesh got eaten by Khorne, he would shrug and keep working. His project is biological. That was the only Chaos character with an actual plan for after the galaxy ends, Kiran said.
I pushed back at the time. I thought the rejection of Chaos was a narrative trick, a way to make Bile sympathetic without actually costing the character anything, and I said so with more confidence than the argument deserved. I don’t actually believe that now. I’ve changed my mind on him slowly in the years since. I’ve also never finished Clonelord. The paperback is on my shelf. I keep meaning to pick it up again and instead I buy more Tyranids, which is its own kind of problem.
The Creations of Bile detachment
Games Workshop named one of the new Chaos Space Marines detachments Creations of Bile. You field enhanced CSM with improved stats, you play into a Bile-coded identity, you can include Fabius himself as the centrepiece character. The detachment is named after him. It honours his long legacy of handing out Stim Implants and surgical enhancements to whoever will pay. It sits in the Chaos Space Marines codex.
This was probably a commercial decision. A new EC codex needs to focus on Slaanesh and Fulgrim, because the pitch is the Legion coming home to its god. Bile spans multiple armies. Keeping his rules in CSM means more people can use him. The side effect is that the Clone Lord whose surgical work made the post-Heresy Slaanesh Marines possible (the altered brain chemistry, the rewired pleasure centres) is absent from the shelf GW is selling those Slaanesh Marines on. Like an ex you split with amicably who isn’t invited to the wedding. Still sent you a card, though.
I don’t think this is permanent. GW has moved Bile around before. He’s been an Emperor’s Children character, a generic CSM character, a rogue warband leader, a Black Library protagonist, all within the same fifteen years. I’d bet the next edition of the EC codex brings him back in some form, maybe with an updated model that finally retires the one from 1998 that looks like a dentist. But that’s a guess.
Where that leaves him
Fabius Bile’s current status is what it usually is. Isolated, running his own faction, refusing to commit, and building towards something no one else in Chaos is building towards. The Consortium still operates. The Vesalius (his stolen Gladius frigate, crewed by mutants and New Men and a mutilated Aeldari webway-opener named Key) still flies. The cloak of Istvaan V skins is presumably still in a closet somewhere. Somewhere on a hundred worlds his New Men are growing up quietly next door to ordinary Imperial citizens, and the Inquisition isn’t finding all of them.
If you want to field him in 40K you run Chaos Space Marines with the Creations of Bile detachment. If you want to read him now it’s still Reynolds’s trilogy, Primogenitor then Clonelord then Manflayer, in that order. He shows up in Siege of Terra and Angel Exterminatus too. He doesn’t appear in the new Champions of Slaanesh box.
