关于bos的codex

vaststars

问下，这个愚蠢的codex是啥时候出现的。123从来没见过
曾经在以前的时候我记得问过npc bos是个啥组织。当时的回答大概是：收集并记录科技，以备人类复兴，同时封存危险科技，防止人类自我毁灭，最后向外逐渐传播技术。
fnv中长老说关于他们codex，不可让外人加入这段还好说
其中还说过一句，跟以前说的完全不一样。大意就是 科技我们拥有，外人无法获得。

那么问题就集中在这个codex上了，啥时候这玩意冒出来的？似乎是fnv新冒出来？ fallout wiki没有找到答案

wiki关于对外关系一项:
The Brotherhood does not like to share their choicest technological bits with others, despite the obvious benefits their technology could bring to the Wasteland. It is a commonly accepted truth within the Brotherhood that the people of the Wasteland are not responsible enough to use (and maintain) all of the technology the BoS has at their disposal. They are known for trading some of their technologies with frontier communities and the states of the New California Republic in exchange for food and other resources, but they keep the more sensitive and advanced technologies to themselves.
