Craftworld Eldar, properly called the Asuryani, are the largest surviving branch of the Eldar race. They live aboard continent-sized world-ships called craftworlds, drifting through space and the Webway to stay one step ahead of the Chaos god Slaanesh.
What a craftworld actually is
A craftworld is a self-sufficient realm the size of a continent, home to tens of millions of Eldar. Each one has its own culture, its own armies, and its own way of surviving.
They started out small. Before the Fall, craftworlds were trading vessels that spent centuries crossing the void and the Webway, carrying hundreds of families at a time. The ships were built in enormous star docks by Bonesingers. Every return home showed the crews a civilisation sinking further into excess, which is why so many of them were ready to run when everything fell apart.
Since then the original hulls have grown massively, often ten or a hundred times their old size. Most carry stretches that lie in ruin, waiting to be reclaimed.
How they survive
Craftworlds aren’t just ships. They’re partly alive. An Infinity Circuit runs through the structure, powered by psychic energy, and the whole vessel responds to the emotions and thoughts of the Eldar aboard in an almost organic way.
Inside there’s an artificial sun, forests, lakes, beaches, and wildlife. Those green zones keep the air breathable and supply renewable resources. There are concert halls lit by incandescent moths, and vast docks holding the fleets that carry Eldar armies into the Webway.
The interiors also sit partly in a fourth spatial dimension, so every level rests beneath another, even the spires that look like they should be the top.
- Propulsion comes from enormous solar sails that soak up starlight.
- Power can be released as light or heat as needed.
- Not every craftworld escaped the birth of Slaanesh. The ones that didn’t were destroyed in the psychic overspill.
Why they matter
The Asuryani are what’s left of a species that once ruled the galaxy. They know it, and it shapes everything they do. Every craftworld follows a Path, a disciplined way of life designed to keep Eldar from sliding back into the behaviour that birthed a god.
That makes them tragic and dangerous in equal measure. They’ll ally with anyone, including the Imperium, if it buys their people another century. They’ll also sacrifice millions of other lives without hesitating if the alternative is extinction.
How they connect to the wider lore
Craftworld Eldar sit alongside the other Eldar factions: the Drukhari of Commorragh, the Harlequins of the Webway, and the Exodites on their maiden worlds. They share a history and a curse, but almost nothing else.
Their most famous craftworlds, like Ulthwé, Biel-Tan, and Saim-Hann, appear throughout the setting’s fiction and tabletop game. Each has a distinct character, from Ulthwé’s seers to Saim-Hann’s wild riders.
| Craftworld | Known for |
|---|---|
| Ulthwé | Powerful seers and a doomed prophecy |
| Biel-Tan | Militant, wants to rebuild the empire |
| Saim-Hann | Wild Rider clans and fast attack |

FAQ
Are Craftworld Eldar the same as Aeldari?
Aeldari is the overall species name. Craftworld Eldar, or Asuryani, are one branch of it, distinct from the Drukhari, Harlequins, and Exodites.
Why do Craftworld Eldar wear soulstones?
A soulstone captures an Eldar’s spirit at death so Slaanesh can’t consume it. The stone is later placed into the craftworld’s Infinity Circuit.
How big is a craftworld?
Continent-sized, with populations in the tens of millions. The original trading hulls at their core are now a small fraction of the whole.
