They don’t have souls. Literally. If you walked into a room with one, you’d probably feel a sudden, inexplicable urge to vomit or just run away as fast as possible. That’s the "gift" of the Untouchable, and it's exactly what makes the Sisters of Silence 40k one of the most terrifying, yet misunderstood, factions in the entire Warhammer universe.
People usually group them in with the Adeptus Custodes—the "banana boys" in gold armor—and call it a day. That’s a mistake. While they are technically the "Left Hand of the Emperor," these women aren't just support pieces or "walking null-fields" for the big guys. They are the Imperium's premier internal security force, the jailers of the soul, and the only reason the golden throne hasn't flickered out like a cheap lightbulb.
Why the Sisters of Silence 40k are "Blanks"
In 40k, everything has a reflection in the Warp. Except for them. They possess the Pariah Gene, a rare mutation that makes them a psychic void. Imagine a world where everyone is a radio transmitter, and suddenly you meet someone who is a literal black hole for signal. That’s a Sister of Silence.

This isn't just a "cool power." It’s a social death sentence. Most people in the Imperium hate them instinctively. It’s an evolutionary revulsion; your brain sees something that looks human but has no spiritual footprint, and it screams predator.
The Vow of Tranquility
They don't talk. Honestly, it’s not because they can’t. It’s a choice. Upon being fully inducted, every sister takes the Vow of Tranquility. They communicate through complex sign languages: Thoughtmark for deep philosophy and nuance, and Battlemark for when things are actually exploding.
There's a gritty fan theory—backed up by some of the Horus Heresy novels—that the Emperor demanded their silence because they are the only ones who can see him for what he really is. No glamours. No psychic aura. Just a man on a chair. If they could talk, they might say something the Inquisition wouldn't like.
They Aren't Just "Sisters of Battle" Lite
I see this all the time on Reddit. "Why play Sisters of Silence when I can just play Adepta Sororitas?"
First off, they are completely different organizations. The Sisters of Battle are religious fanatics who worship the Emperor as a god. The Sisters of Silence? They are secular. They remember the Imperial Truth. They don't pray; they hunt.
- Role: Witch-hunters and gaolers.
- The Black Ships: They run the massive fleet that travels the galaxy, "tithening" (kidnapping) psykers to feed the Golden Throne.
- Authority: They answer to basically nobody except the Emperor and maybe Malcador back in the day.
If a Sister of Silence shows up at your door, she isn't there to convert you. She’s there because you, or your neighbor, has started glowing, and she’s going to put a bolt shell in that problem before a daemon crawls out of it.
The Tabletop Struggle: How to Actually Use Them
Let's be real for a second. On the tabletop, the Sisters of Silence 40k have had a rough time. For a while, they didn't even have their own codex. They were just "the other half" of the Adeptus Custodes book.

Currently, in 10th Edition, they usually show up as part of the Null Maiden Vigil or the Talons of the Emperor detachment. If you’re trying to run a pure Sisters of Silence list, you’re basically a masochist. It’s expensive. You’re looking at $60 for five models, and to hit 2,000 points, you’ll need a literal army of them.
Unit Breakdown
- Prosecutors: The basic infantry. They carry bolters. They’re cheap objective holders.
- Vigilators: These are the ones with the massive Executioner Greatblades. They hit like a truck in melee but die to a stiff breeze.
- Witchseekers: Flamers. Lots of flamers. They are great for clearing out "chaff" units and making psykers regret their life choices.
- Knight-Centura: Your generic leader.
- Aleya: The named hero. She’s a beast in combat, especially when paired with Valerian (though he’s a Custode).
The main problem? They are T3 with 1 Wound. They die to a standard bolt pistol. If you aren't hiding them in an Anathema Psykana Rhino, they’re just expensive target practice. But against a Thousand Sons or Grey Knights player? They are a nightmare. They turn off psychic buffs and force "Hazardous" checks just by standing nearby.
Jenetia Krole: The Ghost Commander
You can't talk about the Sisterhood without mentioning Jenetia Krole. During the Siege of Terra, she was a literal ghost. Her "blank" aura was so strong that people—even allies—literally couldn't see her. She’d be standing right next to a soldier, carving through World Eaters, and the guy wouldn't even realize she was there.
She eventually died during the Siege, and the most tragic part? The guy who killed her (Kharn the Betrayer) didn't even know he’d done it. He just felt his axe hit something in the air. That’s the Sisters of Silence in a nutshell: the most important, invisible heroes of the Imperium who get absolutely zero thanks for it.
Actionable Tips for New Collectors
If you're looking to start a Sisters of Silence 40k force or just add them to your Custodes, don't just buy boxes at random.
- Magnetize the arms: The kit for Prosecutors, Vigilators, and Witchseekers is the exact same box. If you magnetize them, you can swap between bolters, swords, and flamers depending on the meta.
- Buy the Combat Patrol: The Adeptus Custodes Combat Patrol usually comes with 10 Sisters. It’s the most cost-effective way to get them.
- Focus on Rhinos: You need transport. Without a Rhino, your Sisters will never make it across the board to use those greatswords.
- Use them as "Screeners": In a Custodes list, use Sisters to stand in front of your expensive golden guards. They eat the smites and psychic powers so your 70-point models don't have to.
The Sisterhood is finally getting some love in the lore again, especially with Guilliman bringing them back into the fold after they spent 10,000 years forgotten in the fringes. They are the ultimate "anti-meta" choice. Plus, the gold and bronze armor looks incredible on a shelf.
Start with a single squad of five. Build them as Prosecutors. Park them on your home objective and watch your opponent realize they can’t teleport anything near them. It's a small start, but in the silent war, that’s often all you need.
