Of all the septs raised during the First and Second Spheres of Expansion, none is so devoted to the pursuit of knowledge as Bork'an. Its worlds are given over to the great work of the Earth Caste, a sprawling tapestry of academies, arcane laboratories, orbital observatories and the manufactories in which theory is forged into hard reality. Here many of the Empire's proudest innovations were first conceived, from the stasis field to the earliest piloted battlesuits, and the sept guards its reputation as the wellspring of T'au science with a quiet, unshakeable pride.
That devotion shapes the way Bork'an makes war. Its systems hold rich mineral worlds whose yield allows the sept to equip its warriors with weapons of unusually fine manufacture, often the newest experimental patterns the Earth Caste dares to field. Bork'an munitions strike further and truer than the Empire's common issue, and the sept willingly tests unproven armaments in live battle, reasoning that a weapon perfected under fire will one day preserve countless lives.
The temperament of a Bork'an fighting cadre mirrors its homeworlds. Its Fire Warriors are cerebral and restrained, disdaining reckless valour in favour of patient, calculated marksmanship. They hold their fire until the perfect instant, then annihilate the foe from a distance at which the enemy can scarcely reply. It is whispered, too, that Bork'an science teams were spirited away in secret to the abandoned sept of N'dras to birth the deadly Ghostkeel, a rumour the sept neither confirms nor denies.
T'au Empire
Order of battle
The Bork'an Sept field the units of the T'au Empire — a detachment from the roster:
Kindred formations
Other T'au Empire formations
Dal'yth SeptDal'yth is the beating heart of T'au commerce, a First Sphere world whose culture is dominated by the silver-tongued merchants and diplomats of the Water Caste. More cosmopolitan than any other sept, its worlds teem with aliens of a hundred species who trade, treat and dwell alongside the T'au. It was Dal'yth's envoys who bound the Demiurg to the Greater Good, and its markets are counted among the Nineteen Wonders of the Empire.
Farsight EnclavesThe Farsight Enclaves are a cluster of fortress-worlds beyond the Damocles Gulf, ruled by the renegade Fire Caste hero the Imperium names Commander Farsight. Severed from the wider Empire and forbidding all Ethereals within their borders, the Enclaves keep to the old warrior traditions and trust the blade and the battlesuit above the words of any spiritual master. To the T'au they are the Forbidden Zone, a heresy that endures; to their own people they are a free realm guarded by the finest commanders alive.
Sa'cea SeptA sprawling and populous sept whose vast manufactories and shipyards keep the empire's war machine supplied.
T'au SeptThe homeworld sept and spiritual capital of the empire, birthplace of the Ethereal caste's founding vision.
Vior'la SeptA volcanic frontier sept renowned for producing the empire's most aggressive commanders and battlesuit pilots.
