Overview 概述

Led by the revered Commander Shadowsun, the Fifth Sphere was launched into the Startide Nexus, sometime after the Great Rift's creation, when contact was made with Commander Surestrike and the remnants of the Fourth Sphere of Expansion. When Shadowsun and her forces emerged from the Startide Nexus, they were greeted by the survivors of the Fourth Sphere and welcomed to the area of space they had named the Nem'yar Atoll. Shadowsun then integrated the remnants of the Fourth Sphere into her forces and began expanding the size of the Nem'yar Atoll's domain. However this expansion was brought to a halt several months later, when a massive Death Guard armada appeared within the Nem'yar Atoll and began moving towards the Startide Nexus. Though caught by surprise, Shadowsun quickly rallied her forces against the Chaos invaders and engaged in a desperate battle to prevent the Death Guard from reaching the Startide Nexus and gaining a pathway to the heartlands of the T'au Empire.

在备受尊敬的影阳指挥官的领导下，第五界扩张在大裂隙形成后的某个时候被发射到星潮枢纽，当时与确击指挥官和第四界扩张的残余部分取得了联系。当影阳和她的部队从星潮枢纽出来时，他们受到了第四界幸存者的欢迎，并欢迎他们来到他们命名为内姆'亚尔环礁的太空区域。影阳随后将第四界的残余部分整合到她的部队中，并开始扩大内姆'亚尔环礁的范围。然而，几个月后，当一支庞大的死亡守卫舰队出现在内姆'亚尔环礁内并开始向星潮枢纽移动时，这一扩张停止了。尽管感到意外，影阳还是迅速召集她的部队对抗混沌入侵者，并进行了一场绝望的战斗，以阻止死亡守卫到达星潮枢纽，并获得通往钛帝国中心地带的道路。

The Fifth Sphere has continued on, battling the Orks of the Ful'na Nebulae as well as scattered Tyranid Hive Fleet remnants. Due to the calamities consuming the Imperium in the aftermath of the Great Rift's formation, little has been seen of the Imperium. However nearby Imperial worlds were rapidly colonized with a violent eagerness on the part of the former commanders of the Fourth that saw mass purges uncharacteristic of the Tau. Prisoners were massacred and Auxiliaries were intentionally sacrificed in battle. The Massacre of the Dul'un Lakes and the Eight Days of Infamy are the most famous episodes from this controversy. Eventually, Shadowsun and the Ethereal Council disciplined the Fourth Sphere commanders such as Tash'var Shi Kais with a ritual punishment known as the Malk'la before they were returned to the ranks or sent back to the empire for re-assimilation. After a massacre and bloody Kroot uprising upon the colony of Ky'san, all auxiliaries were removed from contingents of Fourth Sphere Tau.

第五界继续推进，与富尔'纳星云的欧克以及分散的泰伦虫巢舰队残余作战。由于大裂隙形成后帝国遭受的灾难，人们对帝国的了解很少。然而，附近的帝国世界迅速被第四界的前指挥官以强烈的渴望殖民化，他们看到了大规模的清洗，这与钛的情况不符。囚犯被屠杀，辅助军在战斗中被故意牺牲。杜'伦湖大屠杀和八日恶名是这场争论中最著名的事件。最终，影阳和以太议会对塔什'瓦尔·希·凯斯等第四界指挥官进行了纪律处分，并对他们进行了被称为玛尔克'拉的仪式惩罚，然后他们被送回军队或送回帝国重新同化。在基'山殖民地发生大屠杀和血腥的克鲁特叛乱后，所有辅助军都被从钛第四界的特遣队中撤职。

Despite the controversy surrounding Fourth Sphere Tau, the Fifth Sphere has continued at a formidable pace. In the span of several months several planets were occupied and transformed into thriving colonies. Most of the expansion is taking place from the Nem'yar Atoll, far to the north of the Tau Empire proper. Ongoing warzones are located at the Chalnath Expanse, Haephos, Astorgius, Riatov, and Vorotheion.

尽管围绕钛第四界存在争议，但第五界仍以惊人的速度继续发展。在几个月的时间里，几个行星被占领，变成了繁荣的殖民地。大部分的扩张都发生在钛帝国北部的内姆'亚尔环礁。正在进行的战区位于查尔纳特扩区、海弗斯、阿斯特吉斯、里亚托夫和沃罗西翁。

Ultimately, the Battle of the Startide Nexus against the Death Guard mauled the Fifth Sphere fleet, slowing its momentum. Though it is still expanding and capturing new territory, a Sixth Sphere is already being planned.

最终，星潮枢纽之战对抗死亡守卫摧毁了第五界舰队，减缓了其势头。尽管它仍在扩张和占领新的领土，但第六界已经在计划中。
