Saim-Hann is organised not as a single society but as a web of proud kindreds, extended clan-families bound by blood and honour and led by chieftains whose authority rests on prowess and reputation. This clannish structure lends the craftworld a fierce, headstrong character that its more reserved cousins sometimes regard as reckless, though none question the courage of its warriors.
Above all, Saim-Hann is a craftworld of riders. Its people take to the skimming jetbikes and grav-tanks of the Windrider hosts with a passion bordering on obsession, and its armies are built around swift, hard-hitting cavalry that strikes like a thunderbolt and wheels away before the enemy can respond. This love of speed is matched by an elaborate code of honour that governs feuds, challenges, and the settling of debts between kindreds, a ritualised discipline that channels the craftworld's fiery temperament without letting it consume its people. To ride to war with Saim-Hann is to embrace both wild abandon and iron tradition in the same breath.
Aeldari
Order of battle
The Saim-Hann field the units of the Aeldari — a detachment from the roster:
Kindred formations
Other Aeldari formations
Biel-TanThe Swordwind, most militant and idealistic of the great craftworlds, whose people refuse to accept the Aeldari as a spent and dying force. Biel-Tan dreams of rebuilding the shattered empire of old, and its armies are composed of Aspect Warriors in numbers no other craftworld can match, striking with the disciplined ferocity of those who believe their race can still reclaim its lost supremacy.
Craftworld AlaitocAlaitoc is the most remote and inward-looking of the great craftworlds, drifting at the ragged edge of the galaxy far beyond the frontiers of the Imperium. Its people hold to a discipline stricter than that of any other Asuryani, forever watchful against the seductive whispers of She Who Thirsts. From this severity is born a restless tide of wanderers who take up the Path of the Outcast, and Alaitoc sends more Rangers and Pathfinders into the dark between the stars than all its sister worlds combined.
IyandenThe Ghost Craftworld, once among the most populous and splendid of all Aeldari vessels, now a haunted shell that lost the overwhelming majority of its people to catastrophe. To survive at all, Iyanden marches its very dead into battle, animating the spirits of fallen ancestors within wraith constructs so that the honoured departed might still defend the dwindling living.
The YnnariThe Ynnari are the Reborn, a movement that cuts across every division of the Aeldari race in devotion to Ynnead, the long-dormant god of the dead. Craftworlder and Drukhari, Corsair and Harlequin, Exodite and outcast gather beneath the banner of the whispering god, united by the conviction that only his full awakening can deliver their species from oblivion and shatter the tyranny of Slaanesh. Led by the prophet Yvraine and her Triumvirate, they wield the very energy of death as a weapon.
UlthwéThe Damned Craftworld, drifting in the shadow of the Eye of Terror and shielded by the greatest concentration of seers among the Aeldari. Its people live under constant threat from the daemonic horrors that spill from that hellish wound, and this proximity to ruin has forged a somber, disciplined culture that treats prophecy as a weapon and survival as a duty owed to the whole species.
