Firstborn, also known as Principia is the Imperial term for original-template, pre-Primaris Space Marines.
长子，也称为原理，是帝国对原始模板的称呼，即原铸前的星际战士。
History 历史
For ten thousand years from the Great Crusade until the end of the Thirteenth Black Crusade, the Firstborn were simply the Adeptus Astartes. However following the development of Primaris Space Marines by Belisarius Cawl the "Firstborn" as they became known faced the prospect of obsolescence at these larger, physically stronger, and mass produced warriors. Originally, in the early stages of the Indomitus Crusade, most Primaris were produced by Cawl himself and, though developed by the gene-seed of the Primarchs, lacked a distinct identity, instead being gathered in armies known as the Unnumbered Sons; however, as the Crusade progressed, the Unnumbered Sons were distributed to either new Chapters of the Ultima Founding or into existing Space Marine Chapters.
从大远征到第十三次黑色远征结束的一万年里，长子只是阿斯塔特修会。然而，随着贝利撒留·考尔开发了原铸星际战士，他们被称为“长子”的人在这些更大、身体更强壮、大规模生产的战士中面临着被淘汰的前景。最初，在不屈远征的早期阶段，大多数原铸都是由考尔自己制作的，虽然是由原铸的基因种子发展而来的，但缺乏明确的身份，而是聚集在被称为未计之子的军队中；然而，随着远征的推进，未计之子被分发到极限建军的新战团或现有的星际战士战团。
Reaction to Primaris Space Marines 对原铸星际战士的反应
Even though 94% of Chapters have accepted Primaris Marines into their ranks Firstborn-Primaris relations have had issues. To many, the Primaris were new arrivals often recruited away from a Chapter's homeworld and new to the culture, traditions, and ways of the Chapter. Many arrivals from the Unnumbered Sons into existing Chapters felt like strangers. When some Firstborn first saw the Primaris, they regarded them as mutants. This tension was exemplified in the Space Wolves, where many Wolf Lords resisted accepting Primaris Space Marines. While the likes of Krom Dragongaze embraced these new warriors, Logan Grimnar himself was distrustful and say these warriors not of Fenris as means to control the Wolves by Guilliman. However after experiencing the trials of Gaius, Grimnar had a change of heart. In the White Scars, many Firstborn saw that these warriors were not of Chogoris nor knew the ways of their Chapter's culture, but at the same time understood the necessity of Primaris Marines in defending the Imperium.
尽管94%的战团已经接受了原铸星际战士加入他们的行列，但长子和原铸之间的关系仍然存在问题。对许多人来说，原铸是新来的，通常是从战团的家园世界招募来的，对战团的文化、传统和方式都是陌生的。许多从未计之子进入现有战团的人感觉就像陌生人。当一些长子第一次看到原铸时，他们认为他们是变种人。这种紧张关系在太空野狼中得到了体现，许多狼主拒绝接受原铸星际战士。虽然克罗姆·龙瞪等人接受了这些新战士，但罗根·格里姆纳尔本人并不信任他们，并表示这些战士不是芬里斯的战士，而是基里曼控制野狼的手段。然而，在经历了盖乌斯的试炼后，格里姆纳尔改变了主意。在白色伤疤中，许多长子看到这些战士不是巧高里斯人，也不知道他们战团的文化，但同时也明白了原铸星际战士在保卫帝国方面的必要性。
Notable Space Marine officers who have openly expressed distrust of Primaris Space Marines are Flesh Tearers Chapter Master Gabriel Seth and Raven Guard 9th Company Captain Vos Delorn. In the Unforgiven, there was much hesitancy over allowing Primaris Marines into the Inner Circle. In the Black Templars, High Marshal Helbrecht approved of Primaris Space Marines and most of his forces accepted them, but the issue still turned disastrous for the Angevin Crusade.
公开表示对原铸星际战士不信任的著名星际战士军官是撕肉者战团长加百列·赛斯和暗鸦守卫第九连队连长沃斯·德朗。在不可饶恕者中，对于允许原铸星际战士进入内环存在很大的犹豫。在黑色圣堂中，至高元帅赫尔布雷希特批准了原铸星际战士，他的大多数部队都接受了他们，但这个问题对安茹远征来说仍然是灾难性的。
In an attempt and promote unity between Firstborn and Primaris Marines, Roboute Guilliman often used them as political equerries and symbols of his authority. For their part, most Primaris Marines looked to their Firstborn brethren for sage advice, drawing from experiences from their many centuries of conflict. Primaris Marines learned this lesson in the early days of the Indomitus Crusade, where many had fallen in battle due to their lack of experience.
为了促进长子和原铸星际战士之间的团结，罗伯特·基里曼经常将他们用作政治侍从和权威的象征。就他们而言，大多数原铸星际战士从他们几个世纪的冲突中汲取经验，向他们的长子兄弟寻求明智的建议。原铸星际战士在不屈远征的早期就吸取了这一教训，许多人因缺乏经验而在战斗中阵亡。
Originally, Firstborn could not survive being converted into Primaris Marines. However this changed when Ultramarines Chapter Master Marneus Calgar crossed the Rubicon Primaris and became the first Firstborn to survive transitioning into a Primaris Space Marine. Since then, the process has been repeated for Firstborn across multiple Chapters.
起初，长子无法在转变为原铸星际战士后幸存下来。然而，当极限战士战团长马涅乌斯·卡尔加越过原铸界限，成为第一个在过渡到原铸星际战士后幸存下来的长子时，情况发生了变化。从那时起，这一过程在多个战团中对长子进行了重复。
