The Soul Binding is a ritual conducted by the Adeptus Astra Telepathica of the Imperium, which is responsible for creating Astropaths.

灵魂结合是由帝国的星语庭主持的仪式，该仪式负责制造星语者。

Normal psykers are unable to transmit telepathic messages across vast distances through the warp. Astropaths undergo special training over many years before taking part in this special rite, where their minds are brought before the great psychic might of the Emperor himself. During this process, a portion of the Emperor's vast essence is transfered into that of the Astropath. The transference process is a traumatic experience, with not all being successful despite many years of training, with some not surviving and many that do lose much of their sanity. The most visible result of the Soul Binding is damage to the sensitive nerves of the eyes, which leaves almost all Astropaths blind. However, the ritual imparts them greater psychic skills which tends to make up for their lost eyesight and they tend to not act as if they are blind.

普通的灵能者无法通过亚空间远距离传输心灵感应信息。星语者在参加这个特殊的仪式之前，会经过多年的特殊训练，在那里他们的精神会被带到帝皇自己的伟大灵能力量面前。在这个过程中，帝皇的一部分巨大的本质被转移到了星语者。传递过程是一种痛苦的经历，尽管经过多年的训练，但并非所有人都能成功，有些人无法幸存，许多人失去了大部分理智。灵魂结合最明显的结果是对眼睛敏感神经的损伤，这几乎让所有的星语者失明。然而，这种仪式赋予了他们更大的灵能技能，这往往可以弥补他们失去的视力，而且他们往往不会表现得像盲人。

Astropath training ultimately ends with this rite which is a techno arcane initiation ritual that greatly opens their minds to the warp. The ritualistic soul binding to the Emperor can protect many psykers from the perils of the Warp. The entities of the warp are a hideous threat to those psykers who have not undergone the Soul Binding ritual. According to legend by M41, the first psyker to take part in the Soul Binding ritual was Malcador the Sigilite who became forever linked to the Master of Mankind.

星语者训练最终以这个仪式结束，这是一个科技神秘启蒙仪式，极大地打开了他们的心灵。与帝皇绑定的仪式灵魂可以保护许多灵能者免受亚空间的危险。亚空间实体对那些没有经历灵魂结合仪式的灵能者来说是一个可怕的威胁。根据M41的传说，第一个参加灵魂结合仪式的灵能者是掌印者马卡多，他永远与人类之主联系在一起。
