Craftworld - Biel-Tan: The most martial and aggressive of the craftworlds, Biel-Tan has made the decision to try and reforge the Aeldari Empire, by eliminating the younger races who have "usurped" the galaxy. Each craftworld carries the seeds of Aeldari culture. Not all are identical by any means, as each reflects the cultural heritage of its long dead world of origin.Biel-Tan is renowned for the strong warrior ideals of its people. For the Asuryani of Biel-Tan the Way of the Warrior, the life-stage that encompasses the Aspect Warriors, is considered the first step upon the Asuryani Path. Upon reaching physical maturity a Biel-Tan Asuryani becomes an Aspect Warrior, and only once they have fulfilled this role can they continue along the other roles of the Asuryani Path.The Asuryani of Biel-Tan have a strong honour code and believe that the best way to die is in battle fighting the enemies of Biel-Tan. In the centre of the craftworld there is a special Chamber of Heroes where the Spirit Stones of dead Aspect Warriors are placed.When the Runeseers have to make a particularly difficult decision about the future of their craftworld, they retire to the Chamber of Heroes to consult with the warrior dead. The dead of particular battles are arranged together and are often referred to by the name of the battle in which they fell -- for example, the Dead of Corrus fell fighting Chaos on an ancient Aeldari colony world of the same name.When the Asuryani of Biel-Tan go to war they assemble a warhost known as the Bahzhakhain in the Aeldari Lexicon which means "Swordwind" or "Tempest of Blades." The Swordwind's tactic is a single, swift strike and taking the enemy by surprise. This tactic works considerably well with the elite fighting skills of the many Aspect Warriors eliminating the enemy before they can respond.The Biel-Tan therefore make perfect use of the speed and maneuverability of the Wave Serpents and Falcon grav tanks. The main target of the Biel-Tan are non-Aeldari colonists -- particularly non-Aeldari occupying Aeldari Maiden Worlds. It is especially galling to the Aeldari who created these paradise worlds from dead worlds to find them overrun with "inferior" species.The Asuryani of Biel-Tan believe the success of other alien species is a threat to the expansion of the reborn Aeldari Empire. For this reason the Biel-Tan particularly hate the Orks, greenskins being a completely expansionist species, whose occupation of a world quickly becomes permanent.In many cases Biel-Tan have helped Imperial forces that were under heavy attack by Orks and to hunt down Ork Roks before the tide of Orks can overrun a planet. The Swordwind even possess a vehicle that is unique to Biel-Tan. It is a super-heavy gravity tank called a Void Spinner which is armed solely with a huge monofilament cannon which works just like any other monofilament weapon except that it incorporates a techno virus that sterilizes the ground that it touches.This makes it extremely useful against the Orks due to the Orkoid physiology's spore-based method of reproduction, preventing further re-infestation.The symbol of Biel-Tan is the Aeldari Rune of Rebirth and its name literally translated into Low Gothic means the "Rebirth of Ancient Days." The Swordwind Court's battle colours are green and white, often with flowing vines painted on Biel-tan vehicles. Each thorn of these vines represents the death of a hated enemy.Biel-Tan Guardians wear white or grey armour with trim in green. Biel-Tan vehicles are often coloured entirely green, with large areas broken up using a pattern of twisting vines in a contrasting shade. For every kill an Asuryani pilot makes, a thorn is added to the vine.The name of the craftworld is a variation of the Irish Gaelic word Beltane (also known as Beltaine among the ancient Celtic peoples of Europe or May Day, May 1st).The colour scheme of the Biel-Tan craftworld and its forces is generally green and white. The Biel-Tan craftworld can usually can be found drifting among the stellar winds in the southern reaches of the galaxy, relative to Terra, in the Segmentum Tempestus.
