Biel-Tan is defined by refusal. Where other craftworlds have accepted their diminishment, Biel-Tan burns with the conviction that the Aeldari can and must be restored to mastery of the galaxy, and every facet of its society bends toward that purpose. Its people hold themselves apart with an aloof pride even by Aeldari standards, regarding the younger races as usurpers squatting upon worlds that rightfully belong to the elder kind.
This martial idealism expresses itself in the craftworld's armies, which draw disproportionately upon the Aspect Shrines rather than citizen-Guardians. A Biel-Tan host is an elite instrument, a blade of Aspect Warriors deployed with surgical precision, and its onslaughts are known as the Swordwind for the way they descend swift and lethal upon their foes. In recent times the craftworld has suffered grievous wounds, yet its dream endures, and its warriors still march to war certain that the age of Aeldari greatness can be won back one battle at a time.

Order of battle
The Biel-Tan field the units of the Aeldari — a detachment from the roster:
Kindred formations
Other Aeldari formations
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.
Saim-HannThe Wild Host, a craftworld of proud kindred clans who prize speed, daring, and personal honour above the patient strategies of their kin. Saim-Hann wages war from the saddle of skimming jetbikes and grav-tanks, its warriors striking in headlong charges that reflect a fierce, almost barbaric spirit tempered only by an intricate code of martial etiquette.
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.
