Abhumans and Madmen of the Ætern Sector
A downloadable gazetteer
“In an insane age, the madman leads the way!"
Teetering on the edge of the Galaxy, the Ætern Sector is a madhouse swirling around the event horizon of an ancient and unholy Warp anomaly. Populated by no end of mutants, monsters and mystics, it is simultaneously a bastion of Imperial might and an incessant hive of conspiracy, violence and half-fogotten secrets. Some were drawn here by the mysterious Ænigma Damnatio. Others were compelled by the tick-tick-ticking of the Great Clock. The hour of midnight draws near. Time is counting down. Prepare yourself.
ÆTERN IS CALLING.
Abhumans and Madmen of the Ætern Sector is a homebrew expansion and setting gazetteer for the Ætern Sector project, created by the anons of /tg/ more than a decade ago and under continuous refinement and development ever since. We've tried out best to bring the Sector to life with a shocking plethora of new character creation options, monsters, allies, foes, lore, equipment and then some, compatible with Only War and Dark Heresy, 2nd Edition, published by Cubicle 7 games.
By the numbers, Ætern has:
- 43 Homeworld options for Dark Heresy, 2nd Edition, from the Nanoplague-twisted madness of Agharta to the irradiated forge-fortresses of Kronak and the spaceborn monstrosities of the Net of N'Zoagew.
- 23 Regiments for Only War, most with unique gear and abilities. Hunt your prey as a Carstein Dragulman, ride down the foul Eldar as a Cataphract of Aspbed, or take to the hills in defense of your world as a Salonikan Armatole!
- 17 new Elite Advances and Advanced Specialties, from the Frankensteinian Aghartan Half-Eldar to the ghoulish Pale Strain and the utterly alien Sisters of the Abyss.
- 11 new Xenos factions: Pit your wits against the technocratic Vadh'rorc, seek glory against the mighty Zacith, or witness the unbridled anarchy of the Be'enteshaai, and more!
- 57 new NPCs: from alien war machines to war-weary mercenaries and the nightmarish horror-forms of the Black Terror.
- 91 new weapons, upgrades, tools, vehicles and pieces of gear: Equip yourself with the finest of Lionan las-weapons, or wield the Daemon-devouring Shamshirs of Sycorax!
- Spectacular all-original art by Matt Clarke, 101ho, BadConceptArtist, NEY0, MieR, Uncle Krees, Jipowap von Angband, TheTrueGuy, Anonymous, and Konigstein, including an entire sector of heraldic symbols.
- And more!
If you're looking to dive head-first into a new take on the Warhammer 40000 setting full of Gothic intrigue, nightmarish theology, and curiously refreshing mint-based beverages, Ætern is the place for you.

Slowly gathering players for a black crusade game set in Ætern, so many cool worlds for them to do horrible things to.
I shudder to imagine! The next big update is gonna be all Chaos, all the time, so hopefully we'll have some tool and allies for you to work with.
At the rate I prepare games, I'm sure that update will be out with time to spare lmao. Glad to hear about it!
a fascinating setting with great mechanics 👍
