The Veiled Region is a vast unmapped area of Segmentum Pacificus that consists of dense nebulae and newborn stars that suffer from waves of radiation alongside discarded stellar matter whilst being cloaked in stellar dust. Within its expanse is known to reside a number of greenskin pirates, a race of sluggish primtive creatures on a dying world and a few xenos mercenaries as well as traders. Unknown to many, Necrons are known to populate this region of space.

帷幕地区是太平星域的一个巨大的未测绘区域，由致密的星云和新生群星组成，这些群星在被恒星尘掩盖的同时，与被丢弃的恒星物质一起受到辐射波的影响。在这片广袤的地区中，居住着许多绿皮海盗，一个垂死世界上行动迟缓的原始生物种族，以及一些异型雇佣兵以及商人。很多人都不知道，死灵是居住在这个空间区域的。

Since the beginning of recorded history of the Imperium, this area had been referred to as the Veiled Regions. It is known that Explorator Fleets had barely probed the surface of its nebulae since the age of the Great Crusade thus there was only limited knowledge on this region of space. One Rogue Trader is known to had travelled on the outskirts of the Veiled Region before heading to the western edge of the galaxy with his records indicating his limited encounters with some alien species. The limited levels of navigation conducted of this region had been both dangerous and hazardrous with some such as Khrul believing that the reason it remained unexplored is because of the resources needed to penetrate it. Under Imperial law, it was prohibited for any Human settlements to be established within the Veiled Region. Despite this being the case, Human settlements within the Veiled Regions was a persistent yet unproven rumour. Amongst the greatest dangers of this area was its isolation with Astropathic communication being difficult as any psychic communication being reflected back and echoed with only silence being returned to them. Any exploration of the region was thus rarely attempted and never successful.

自帝国有史以来，该地区一直被称为帷幕地区。众所周知，自大远征时代以来，探索者舰队几乎没有探测过其星云的表面，因此对这一空间区域的了解有限。众所周知，一名行商浪人在前往银河系西部边缘之前，曾在帷幕地区的边缘地带航行，他的记录表明他与一些异型物种的有限接触。该地区有限的导航水平既不安全又危险，赫鲁尔等一些人认为，该地区仍未被探索的原因是渗透所需的资源。根据帝国法律，禁止在帷幕地区建立任何人类定居点。尽管如此，帷幕地区的人类住区仍然是一个持续存在但未经证实的谣言。这个地区最大的危险之一是它与星语交流的隔离，因为任何灵能通信都会被反射回来，只会被沉默所回应。因此，对该地区的任何探索都很少尝试，也从未成功。

Baradrin Thaal is noted to had received Archeotech that he claimed he got from a Rogue Trader by the name of Devian who in turn acquired it from the Veiled Regions. The Adeptus Mechanicus were unable to discern this artefacts origin except that it was from a xenos civilization of advanced technological development. Thus, they decided to dispatch Archmagos Voar to finding its source in the Veiled Region and he in turn assembled an Explorator Fleet for this task of hunting down the alien creators of the mysterious mask. This fleet was headed by the flagship Antithesis that was formed from the Martian fleet and consisted of forces that Voar believed would have little trouble in their expedition into the Veiled Region. The fact that the mask resembled a Human led the Mechanicus to believe that Human settlements resided in the Veiled Region that were either under xenos domination or serving as allies thus Voar was tasked with liberating them whilst bringing them under the Imperium of Man. The expedition was within its second year when the Veil was penetrated as the Mechanicus Explorator fleet passed through light years of thickening nebulae and stellar clouds whereupon they went through the clear void of space.

巴拉德林·塔尔据说得到了考古科技，他声称自己是从一个名叫德维安的行商浪人那里得到的，而德维安又从帷幕地区获得了它。机械神教无法辨别这些造物的来源，除非它来自技术先进的异型文明。因此，他们决定派遣大贤者沃亚尔前往帷幕地区寻找其来源，他又组建了一支探索者舰队，负责追捕神秘面具的异型创造者。这支舰队由火星舰队组成的旗舰对立号率领，由沃亚尔认为在探索帷幕地区时不会遇到什么麻烦的部队组成。面具类似于人类的事实使机械教相信，人类定居点居住在被异型统治或作为盟友的帷幕地区，因此沃亚尔的任务是解放他们，同时将他们置于人类帝国之下。考察队在第二年内，当机械教探索者舰队穿过光年厚的星云和恒星云时，帷幕被穿透，于是他们穿过了清澈的虚空。

During this time, the Soul Drinkers Chapter that had been declared traitors by the Imperium took their Space Hulk, the Brokenback, into the Veiled Region to escape persecution where it was noted that the area had not been explored by the Imperium for thousands of years. This saw them attempt to escape the Adeptus Mechanicus leading them deeper into the Veiled Region to the point that Chapter Master Sarpedon was informed that they were in unexplored space. At this time, the Necrons native to this area of space awakened from their slumber which forced the Adeptus Mechanicus to ally with the Soul Drinkers as well as the Human inhabitants native to the Veiled Region to combat this threat.

在此期间，被帝国宣布为叛徒的饮魂者战团带着他们的太空废船断背号进入了帷幕地区，以逃避迫害，注意到该地区数千年来没有被帝国探索过。这让他们试图逃离机械神教，带领他们深入神秘区域，以至于战团长萨尔佩冬被告知他们处于未探索的空间。此时，居住在这片空间的死灵从沉睡中醒来，这迫使机械神教与饮魂者以及帷幕地区的人类居民结盟，以对抗这一威胁。

It is among the many areas of the Galaxy, that have greatly suffered at the hands of the World Eaters Traitor Legion.

它是银河系许多地区之一，在吞世者叛徒军团手中遭受了巨大的痛苦。
