Of all the alien languages, this junkyard civilization’s language and culture was the one most familiar to mankind.
At the time mankind was cornered into a dead-end, they had plenty of the junkyard civilization’s literature but no way to understand them. After pooling the resources of many linguists and historians, mankind finally had a cipher available to translate the junkyard civilization’s language. Over the years, the translation effort hadn’t stopped. There were new corrections and additions made to the cipher. Overall, the Hope’s experts’ familiarity with this space language was similar to how they were familiar with English, French, or German.
