Later sources would greatly increase the time frame between the two. The official English Gundam.info Archives website, created by Sunrise, describes Correct Century as, "similar to early 20th Century America, but is actually set tens of thousands of years in the distant future and incorporates every Universal Century and Another Gundam timeline that ever existed." The manual for the Master Grade Turn X gunpla, released in June 2014, would further explain the Dark History as the original "Mobile Suit Gundam" marking the beginning of humanity's space age, and "Turn A" as the final result, with all other "Gundam" series, including those that were produced prior to "Turn A": "G Gundam", "Gundam Wing", and "Gundam X", and those produced after: "Gundam SEED", "Gundam 00", and "Gundam AGE", taking place in the tens of thousands of years in between the two shows.
